     This application claims priority under Title 35, United States Code 119(e) from Provisional Application Ser. No. 60/116,507, filed Jan. 20, 1999. 
    
    
     FIELD OF THE INVENTION 
     This invention relates to hard surface cleaning products comprising particular types of improved alkylbenzene sulfonate surfactant mixtures adapted for use by controlling compositional parameters, especially a 2/3-phenyl index and a 2-methyl-2-phenyl index. 
     BACKGROUND OF THE INVENTION 
     The developer and formulator of surfactants for hard surface cleaning must consider a wide variety of possibilities with limited (sometimes inconsistent) information, and then strive to provide overall improvements in one or more of a whole array of criteria, including performance in the presence of free calcium in complex mixtures of surfactants and polymers, e.g. cationic polymers, formulation changes, enzymes, various changes in consumer habits and practices, and the need for biodegradability. 
     Further, hard surface cleaning should employ materials that enhance the tolerance of the system to hardness, especially to avoid the precipitation of the calcium salts of anionic surfactants. Precipitation of the calcium salts of anionic surfactants is known to cause unsightly deposits on hard surfaces, especially dark hard surfaces. In addition, precipitation of surfactants can lead to losses in performance as a result of the lower level of available cleaning agent. In the context provided by these preliminary remarks, the development of improved alkylbenzene sulfonates for use in hard surface cleaning compositions is clearly a complex challenge. The present invention relates to improvements in such surfactant compositions. 
     It is an aspect of the present invention to provide mixtures of the modified alkylbenzene sulfonate surfactant mixtures which are formulatable to provide cleaning compositions having one or more advantages, including greater product stability at low temperatures, increased resistance to water hardness, greater efficacy in surfactant systems, filming and streaking, improved removal of greasy or particulate body soils, and the like.

     DETAILED DESCRIPTION OF THE INVENTION 
     The hard surface cleaning compositions of this invention comprise a modified alkylbenzene sulfonate surfactant mixture. The essential and optional components of the modified alkylbenzene sulfonate surfactant mixture and other optional materials of the hard surface cleaning compositions herein, as well as composition form, preparation and use, are described in greater detail as follows: (All concentrations and ratios are on a weight basis unless otherwise specified.) The invention, on the other hand, is not intended to encompass any wholly conventional hard surface cleaning compositions, such as those based exclusively on linear alkylbenzene sulfonates made by any process, or exclusively on known unacceptably branched alkylbenzene sulfonates such as ABS or TPBS. 
     The surfactant system will be present in the hard surface cleaning composition at preferably at least about 0.5%, more preferably, at least about 1%, even more preferably at least about 2%, even more preferably still at least about 5%, even more preferably still at least about 8%, most preferably at least about 10%, by weight. Furthermore, the surfactant system will be present in the hard surface cleaning composition at preferably at less than about 90%, more preferably less than about 75%, even more preferably less than about 50%, even more preferably less than about 35%, even more preferably less than about 20%, most preferably less than about 15%, by weight. 
     The conventional surface cleansing additive will be present in the hard surface cleaning composition at preferably at least about 0.5%, more preferably, at least about 1%, even more preferably at least about 2%, even more preferably still at least about 5%, even more preferably still at least about 8%, most preferably at least about 10%, by weight. Furthermore, the conventional surface cleansing additive will be present in the hard surface cleaning composition at preferably at less than about 90%, more preferably less than about 75%, even more preferably less than about 50%, even more preferably less than about 35%, even more preferably less than about 20%, most preferably less than about 15%, by weight. This conventional surface cleansing additive is selected from the group comprising builders, bleaching compounds, aqueous liquid carrier, co-solvents, polymeric additives, pH adjusting materials, hydrotropes, co-surfactants and mixtures thereof, all of which are hereinafter defined. 
     As used herein, “hard surfaces”, typically refers to floors, walls, windows, kitchen and bathroom furniture, appliances and dishes. 
     It is preferred that when the detergent compositions of the present invention comprise any alkylbenzene sulfonate surfactant other than said modified alkylbenzene sulfonate surfactant mixture (for example as a result of blending into the detergent composition one or more commercial, especially linear, typically linear C 10 -C 14 , alkylbenzene sulfonate surfactants), said composition is further characterized by an overall 2/3-phenyl index of at least about 200, preferably at least about 250, more preferably at least about 350, more preferably still, at least about 500, wherein said overall 2/3-phenyl index is determined by measuring 2/3-phenyl index, as defined herein, on a blend of said modified alkylbenzene sulfonate surfactant mixture and said any other alkylbenzene sulfonate to be added to said composition, said blend, for purposes of measurement, being prepared from aliquots of said modified alkylbenzene sulfonate surfactant mixture and said other alkylbenzene sulfonate not yet exposed to any other of the components of said composition; and further provided that when said composition comprises any alkylbenzene sulfonate surfactant other than said modified alkylbenzene sulfonate surfactant mixture (for example as a result of blending into the composition one or more commercial, especially linear, typically linear C 10 -C 14 , alkylbenzene sulfonate surfactants), said composition is further characterized by an overall 2-methyl-2-phenyl index of less than about 0.3, preferably from 0 to 0.2, more preferably no more than about 0.1, more preferably still, no more than about 0.05, wherein said overall 2-methyl-2-phenyl index is to be determined by measuring 2-methyl-2-phenyl index, as defined herein, on a blend of said modified alkylbenzene sulfonate surfactant mixture and any other alkylbenzene sulfonate to be added to said composition, said blend, for purposes of measurement, being prepared from aliquots of said modified alkylbenzene sulfonate surfactant mixture and said other alkylbenzene sulfonate not yet exposed to any other of the components of said composition. These provisions may appear somewhat unusual, however they are consistent with the spirit and scope of the present invention, which encompasses a number of economical but less preferred approaches in terms of overall cleaning performance, such as blending of the modified alkylbenzene sulfonate surfactants with conventional linear alkylbenzene sulfonate surfactants either during synthesis or during formulation into the composition. Moreover, as is well known to practitioners of hand dishwashing analysis, a number of hand dishwashing adjuncts (paramagnetic materials and sometimes even water) are capable of interfering with methods for determining the parameters of alkylbenzene sulfonate surfactant mixtures as described hereinafter. Hence wherever possible, analysis should be conducted on dry materials before mixing them into the compositions. 
     In one prefered embodiment the modified alkylbenzene sulfonate surfactant mixture in the hand dishwashing composition accoring to the composition according to the first embodiment is prepared by a process comprising a step selected from: 
     blending a mixture of branched and linear alkylbenzene sulfonate surfactants having a 2/3-phenyl index of 500 to 700 with an alkylbenzene sulfonate surfactant mixture having a 2/3-phenyl index of 75 to 160 (typically this alkylbenzene sulfonate surfactant is a commercial C 10 -C 14  linear alkylbenzene sulfonate surfactant, e.g., DETAL® process LAS or HF process LAS though in general any commercial linear (LAS) or branched (ABS, TPBS) type can be used); and 
     blending a mixture of branched and linear alkylbenzenes having a 2/3-phenyl index of 500 to 700 with an alkylbenzene mixture having a 2/3-phenyl index of 75 to 160 and sulfonating said blend. 
     Moreover, the invention encompasses the addition of useful hydrotrope precursors and/or hydrotropes, such as C 1 -C 8  alkylbenzenes, more typically toluenes, cumenes, xylenes, naphthalenes, or the sulfonated derivatives of any such materials, minor amounts of any other materials, such as tribranched alkylbenzene sulfonate surfactants, dialkylbenzenes and their derivatives, dialkyl tetralins, wetting agents, processing aids, and the like. It will be understood that, with the exception of hydrotropes, it will not be usual practice in the present invention to include any such materials. Likewise it will be understood that such materials, if and when they interfere with analytical methods, will not be included in samples of compositions used for analytical purposes. 
     A preferred modified alkylbenzene sulfonate surfactant mixture according to first embodiment of the present invention has M selected from H, Na, K and mixtures thereof, said a=1, said b=1, said q=1, and said modified alkylbenzene sulfonate surfactant mixture has a 2-methyl-2-phenyl index of less than about 0.3, preferably less than about 0.2, more preferably from 0 to about 0.1. 
     Related to the composition are methods of their use, such as a method contacting soiled tableware in need of cleaning with either a neat or an aqueous solution of the composition of the invention. Such methods may optionally include the step of diluting the composition with water. Furthermore, the composition may be applied, either neat or as an aqueous solution, directly to the tableware or surface to be cleaned or directly to a cleaning implement, such as a sponge or a wash cloth. Such methods are part of the present invention. 
     Such a modified alkylbenzene sulfonate surfactant mixture according can be made as the product of a process using as catalyst a zeolite selected from mordenite, offretite and H-ZSM-12 in at least partially acidic form, preferably an acidic mordenite (in general certain forms of zeolite beta can be used as an alternative but are not preferred). Embodiments described in terms of their making, as well as suitable catalysts, are all further detailed hereinafter. 
     Another preferred modified alkylbenzene sulfonate surfactant mixture according to the first embodiment of the invention consists essentially of said mixture of branched alkylbenzene sulfonates and nonbranched alkylbenzene sulfonates, wherein said 2-methyl-2-phenyl index of said modified alkylbenzene sulfonate surfactant mixture is less than about 0.1, and wherein in said mixture of branched and nonbranched alkylbenzene sulfonates, said average aliphatic carbon content is from about 11.5 to about 12.5 carbon atoms; said R 1  is methyl; said R 2  is selected from H and methyl provided that in at least about 0.7 mole fraction of said branched alkylbenzene sulfonates R 2  is H; and wherein said sum of carbon atoms in R 1 , L and R 2  is from 10 to 14; and further wherein in said mixture of nonbranched alkylbenzene sulfonates, said Y has a sum of carbon atoms of from 10 to 14 carbon atoms, said average aliphatic carbon content of said nonbranched alkylbenzene sulfonates is from about 11.5 to about 12.5 carbon atoms, and said M is a monovalent cation or cation mixture selected from H, Na and mixtures thereof. 
     Definitions 
     Methyl Termini 
     The terms “methyl termini” and/or “terminal methyl” mean the carbon atoms which are the terminal carbon atoms in alkyl moieties, that is L, and/or Y of formula (I) and formula (II) respectively are always bonded to three hydrogen atoms. That is, they will form a CH 3 — group. To better explain this, the structure below shows the two terminal methyl groups in an alkylbenzene sulfonate.                    
     The term “AB” herein when used without further qualification is an abbreviation for “alkylbenzene” of the so-called “hard” or nonbiodegradable type which on sulfonation forms “ABS”. The term “LAB” herein is an abbreviation for “linear alkylbenzene” of the current commercial, more biodegradable type, which on sulfonation forms linear alkylbenzene sulfonate, or “LAS”. The term “MLAS” herein is an abbreviation for the modified alkylbenzene sulfonate mixtures of the invention. 
     Impurities 
     The surfactant mixtures herein are preferably substantially free from impurities selected from tribranched impurities, dialkyl tetralin impurities and mixtures thereof. By “substantially free” it is meant that the amounts of such impurities are insufficient to contribute positively or negatively to the cleaning effectiveness of the composition. Typically there is less than about 5%, preferably less than about 1%, more preferably about 0.1% or less of the impurity, that is typically no one of the impurities is practically detectable. 
     Illustrative Structures 
     The better to illustrate the possible complexity of modified alkylbenzene sulfonate surfactant mixtures of the invention and the resulting detergent compositions, structures (a) to (v) below are illustrative of some of the many preferred compounds of formula (I). These are only a few of hundreds of possible preferred structures that make up the bulk of the composition, and should not be taken as limiting of the invention.                  
                 
                 
                   
     Structures (w) and (x) nonlimitingly illustrate less preferred compounds of Formula (I) which can be present, at lower levels than the above-illustrated preferred types of stuctures, in the modified alkylbenzene sulfonate surfactant mixtures of the invention and the resulting detergent compositions.                    
     Structures (y), (z), and (aa) nonlimitingly illustrate compounds broadly within Formula (I) that are not preferred but which can be present in the modified alkylbenzene sulfonate surfactant mixtures of the invention and the resulting detergent compositions.                    
     Structure (bb) is illustrative of a tri-branched structure not within Formula (I), but that can be present as an impurity. 
     Preferably the branched alkylbenzene sulfonate is the product of sulfonating a branched alkylbenzene, wherein the branched alkylbenzene is produced by alkylating benzene with a branched olefin over an zeolite beta catalyst which may be fluoridated or non-fluoridated, more preferably the zeolite beta catalyst is an acidic zeolite beta catalyst. The preferred acidic zeolite beta catalysts are HF-treated calcined zeolite beta catalysts. 
     In outline, modified alkylbenzene sulfonate surfactant mixtures herein can be made by the steps of: 
     (I) alkylating benzene with an alkylating mixture; 
     (II) sulfonating the product of (I); and (optionally but very preferably) 
     (III) neutralizing the product of (II). 
     Provided that suitable alkylation catalysts and process conditions as taught herein are used, the product of step (I) is a modified alkylbenzene mixture in accordance with the invention. Provided that sulfonation is conducted under conditions generally known and reapplicable from LAS manufacture, see for example the literature references cited herein, the product of step (II) is a modified alkylbenzene sulfonic acid mixture in accordance with the invention. Provided that neutralization step (III) is conducted as generally taught herein, the product of step (III) is a modified alkylbenzene sulfonate surfactant mixture in accordance with the invention. Since neutralization can be incomplete, mixtures of the acid and neutralized forms of the present modified alkylbenzene sulfonate systems in all proportions, e.g., from about 1000:1 to 1:1000 by weight, are also part of the present invention. Overall, the greatest criticalities are in step (I). 
     Thus it is further preferred that in step (I) the alkylation is performed at a temperature of from about 125° C. to about 230° C., preferably from about 175° C. to about 215° C. and at a pressure of from about 50 psig to about 1000 psig, preferably from about 100 psig to about 250 psig. Time for this alkylation reaction can vary, however it is further preferred that the time for this alkylation be from about 0.01 hour to about 18 hours, more preferably, as rapidly as possible, more typically from about 0.1 hour to about 5 hours, or from about 0.1 hour to about 3 hours. 
     In general it is found preferable in step (I) to couple together the use of relatively low temperatures (e.g., 175° C. to about 215° C.) with reaction times of medium duration (1 hour to about 8 hours) in the above-indicated ranges. 
     Moreover, it is contemplated that the alkylation “step” (I) herein can be “staged” so that two or more reactors operating under different conditions in the defined ranges may be useful. By operating a plurality of such reactors, it is possible to allow for material with less preferred 2-methyl-2-phenyl index to be initially formed and, surprisingly, to convert such material into material with a more preferred 2-methyl-2-phenyl index. 
     Thus a surprising discovery as part of the present invention is that one can attain low levels of quaternary alkylbenzenes in zeolite beta catalyzed reactions of benzene with branched olefins, as characterized by a 2-methyl-2-phenyl index of less than 0.1. 
     Alkylation Catalyst 
     The present invention uses a particularly defined alkylation catalyst. Such catalyst comprises a moderate acidity, medium-pore zeolite defined in detail hereinafter. A particularly preferred alkylation catalyst comprises at least partially dealuminized acidic nonfluoridated or at least partially dealuminized acidic fluoridated zeolite beta. 
     Numerous alkylation catalysts are readily determined to be unsuitable. Unsuitable alkylation catalysts include the DETAL® process catalysts, aluminum chloride, HF, and many others. Indeed no alkylation catalyst currently used for alkylation in the commercial production of detergent linear alkylbenzenesulfonates is suitable. 
     In contrast, suitable alkylation catalyst herein is selected from shape-selective moderately acidic alkylation catalysts, preferably zeolitic. More particularly, the zeolite in such catalysts for the alkylation step step I is preferably selected from the group consisting of ZSM-4, ZSM-20, and zeolite beta, more preferably zeolite beta, in at least partially acidic form. More preferably, the zeolite in step I (the alkylation step) is substantially in acid form and is contained in a catalyst pellet comprising a conventional binder and further wherein said catalyst pellet comprises at least about 1%, more preferably at least 5%, more typically from 50% to about 90%, of said zeolite, wherein said zeolite is preferably a zeolite beta. More generally, suitable alkylation catalyst is typically at least partially crystalline, more preferably substantially crystalline not including binders or other materials used to form catalyst pellets, aggregates or composites. Moreover the catalyst is typically at least partially acidic zeolite beta. This catalyst is useful for the alkylation step identified as step I in the claims hereinafter. 
     The largest pore diameter characterizing the zeolites useful in the present alkylation process may be in the range of 6Angstrom to 8Angstrom, such as in zeolite beta. It should be understood that, in any case, the zeolitcs used as catalysts in the alkylation step of the present process have a major pore dimension intermediate between that of the large pore zeolites, such as the X and Y zeolites, and the relatively smaller pore size zeolites such as mordenite, offretite, HZSM-12 and HZSM-5. Indeed ZSM-5 has been tried and found inoperable in the present invention. The pore size dimensions and crystal structures of certain zeolites are specified in ATLAS OF ZEOLITE STRUCTURE TYPES by W. M. Meier and D. H. Olson, published by the Structure Commission of the International Zeolite Association (1978 and more recent editions) and distributed by Polycrystal Book Service, Pittsburgh, Pa. 
     The zeolites useful in the alkylation step of the instant process generally have at least 10 percent of the cationic sites thereof occupied by ions other than alkali or alkaline-earth metals. Typical but non-limiting replacing ions include ammonium, hydrogen, rare earth, zinc, copper and aluminum. Of this group, particular preference is accorded ammonium, hydrogen, rare earth or combinations thereof. In a preferred embodiment, the zeolites are converted to the predominantly hydrogen form, generally by replacement of the alkali metal or other ion originally present with hydrogen ion precursors, e.g., ammonium ions, which upon calcination yield the hydrogen form. This exchange is conveniently carried out by contact of the zeolite with an ammonium salt solution, e.g., ammonium chloride, utilizing well known ion exchange techniques. In certain preferred embodiments, the extent of replacement is such as to produce a zeolite material in which at least 50 percent of the cationic sites are occupied by hydrogen ions. 
     The zeolites may be subjected to various chemical treatments, including alumina extraction (dealumination) and combination with one or more metal components, particularly the metals of Groups IIB, III, IV, VI, VII and VIII. It is also contemplated that the zeolites may, in some instances, desirably be subjected to thermal treatment, including steaming or calcination in air, hydrogen or an inert gas, e.g. nitrogen or helium. 
     A suitable modifying treatment entails steaming of the zeolite by contact with an atmosphere containing from about 5 to about 100% steam at a temperature of from about 250° C. to 1000° C. Steaming may last for a period of between about 0.25 and about 100 hours and may be conducted at pressures ranging from sub-atmospheric to several hundred atmospheres. 
     In practicing the desired alkylation step of the instant process, it may be useful to incorporate the above-described intermediate pore size crystalline zeolites in another material, e.g., a binder or matrix resistant to the temperature and other conditions employed in the process. Such matrix materials include synthetic or naturally occurring substances as well as inorganic materials such as clay, silica, and/or metal oxides. Matrix materials can be in the form of gels including mixtures of silica and metal oxides. The latter may be either naturally occurring or in the form of gels or gelatinous precipitates. Naturally occurring clays which can be composited with the zeolite include those of the montmorillonite and kaolin families, which families include the sub-bentonites and the kaolins commonly known as Dixie, McNamee-Georgia and Florida clays or others in which the main mineral constituent is halloysite, kaolinite, dickite, nacrite or anauxite. Such clays can be used in the raw state as originally mined or initially subjected to calcination, acid treatment or chemical modification. 
     In addition to the foregoing materials, the intermediate pore size zeolites employed herein may be compounded with a porous matrix material, such as alumina, silica-alumina, silica-magnesia, silica-zirconia, silica-thoria, silica-beryllia, and silica-titania, as well as ternary combinations, such as silica-alumina-thoria, silica-alumina-zirconia, silica-alumina-magnesia and silica-magnesia-zirconia. The matrix may be in the form of a cogel. The relative proportions of finely divided zeolite and inorganic oxide gel matrix may vary widely, with the zeolite content ranging from between about 1 to about 99% by weight and more usually in the range of about 5 to about 80% by weight of the composite. 
     A group of zeolites which includes some useful for the alkylation step herein have a silica:alumina ratio of at least 10:1, preferably at least 20:1. The silica:alumina ratios referred to in this specification are the structural or framework ratios, that is, the ratio for the SiO 4  to the AlO 4  tetrahedra. This ratio may vary from the silica:alumina ratio determined by various physical and chemical methods. For example, a gross chemical analysis may include aluminum which is present in the form of cations associated with the acidic sites on the zeolite, thereby giving a low silica:alumina ratio. Similarly, if the ratio is determined by thermogravimetric analysis (TGA) of ammonia desorption, a low ammonia titration may be obtained if cationic aluminum prevents exchange of the ammonium ions onto the acidic sites. These disparities are particularly troublesome when certain treatments such as the dealuminization methods described below which result in the presence of ionic aluminum free of the zeolite structure are employed. Due care should therefore be taken to ensure that the framework silica:alumina ratio is correctly determined. 
     When the zeolites have been prepared in the presence of organic cations they are catalytically inactive, possibly because the intracrystalline free space is occupied by organic cations from the forming solution. They may be activated by heating in an inert atmosphere at 540° C. for one hour, for example, followed by base exchange with ammonium salts followed by calcination at 540° C. in air. The presence of organic cations in the forming solution may not be absolutely essential to the formation of the zeolite; but it does appear to favor the formation of this special type of zeolite. Some natural zeolites may sometimes be converted to zeolites of the desired type by various activation procedures and other treatments such as base exchange, steaming, alumina extraction and calcination. The zeolites preferably have a crystal framework density, in the dry hydrogen form, not substantially below about 1.6 g.cm −3. The dry density for known structures may be calculated from the number of silicon plus aluminum atoms per 1000 cubic Angstroms, as given, e.g., on page 19 of the article on Zeolite Structure by W. M. Meier included in “Proceedings of the Conference on Molecular Sieves, London, April 1967”, published by the Society of Chemical Industry, London, 1968. Reference is made to this paper for a discussion of the crystal framework density. A further discussion of crystal framework density, together with values for some typical zeolites, is given in U.S. Pat. No. 4,016,218, to which reference is made. When synthesized in the alkali metal form, the zeolite is conveniently converted to the hydrogen form, generally by intermediate formation of the ammonium form as a result of ammonium ion exchange and calcination of the ammonium form to yield the hydrogen form. It has been found that although the hydrogen form of the zeolite catalyzes the reaction successfully, the zeolite may also be partly in the alkali metal form. 
     Prefered zeolite catalysts include zeolite beta, HZSM-4, HZSM-20 and HZSM-38. Most prefered catalyst is acidic zeolite beta. A zeolite beta suitable for use herein is disclosed in U.S. Pat. No. 3,308,069 to which reference is made for details of this zeolite and its preparation. 
     Zeolite beta catalysts in the acid form are also commercially available as Zeocat PB/H from Zeochem. Other zeolite beta catalysts suitable for use can be provided by UOP Chemical Catalysts and Zeolyst International. 
     Most generally, alkylation catalysts may be used herein provided that the alkylation catalyst 1) can accommodate into the smallest pore diameter of said catalyst said branched olefins described herein and 2) selectively alkylate benzene with said branched olefins and/or mixture with nonbranched olefins with sufficient selectivity to provide the 2/3-Ph index values defined herein. 
     In one preferred mode, a hydrotrope or hydrotrope precursor is added either after step (I), during or after step (II) and prior to step (III) or during or after step (III). The hydrotropes are selected from any suitable hydrotrope, typically a sulfonic acid or sodium sulfonate salt of toluene, cumene, xylene, napthalene or mixtures thereof. The hydrotropes precursors are selected from any suitable, hydrotrope precursor typically toluene, cumene, xylene, napthalene or mixtures thereof. 
     Sulfonation and Workup or Neutralization (Steps II/III) 
     Preferably the sulfonating step (II) is performed using a sulfonating agent, preferably selected from the group consisting of sulfuric acid, sulfur trioxide with or without air, chlorosulfonic acid, oleum, and mixtures thereof. Furthermore, it is preferable in step (II) to remove components other than monoalkylbenzene prior to contacting the product of step (I) with sulfonating agent. 
     In general, sulfonation of the modified alkylbenzenes in the instant process can be accomplished using any of the well-known sulfonation systems, including those described in “Detergent Manufacture Including Zeolite Builders and other New Materials”, Ed. Sittig., Noyes Data Corp., 1979, as well as in Vol. 56 in “Surfactant Science” series, Marcel Dekker, New York, 1996, including in particular Chapter 2 entitled “Alkylarylsulfonates: History, Manufacture, Analysis and Environmental Properties”, pages 39-108 which includes 297 literature references. This work provides access to a great deal of literature describing various processes and process steps, not only sulfonation but also dehydrogenation, alkylation, alkylbenzene distillation and the like. Common sulfonation systems useful herein include sulfuric acid, chlorosulfonic acid, oleum, sulfur trioxide and the like. Sulfur trioxide/air is especially preferred. Details of sulfonation using a suitable air/sulfur trioxide mixture are provided in U.S. Pat. No. 3,427,342, Chemithon. Sulfonation processes are further extensively described in “Sulfonation Technology in the Detergent Industry”, W. H. de Groot, Kluwer Academic Publishers, Boston, 1991. 
     Any convenient workup steps may be used in the present process. Common practice is to neutralize after sulfonation with any suitable alkali. Thus the neutralization step can be conducted using alkali selected from sodium, potassium, ammonium, magnesium and substituted ammonium alkalis and mixtures thereof. Potassium can assist solubility, magnesium can promote soft water performance and substituted ammonium can be helpful for formulating specialty variations of the instant surfactants. The invention encompasses any of these derivative forms of the modified alkylbenzenesulfonate surfactants as produced by the present process and their use in consumer product compositions. 
     Alternately the acid form of the present surfactants can be added directly to acidic cleaning products, or can be mixed with cleaning ingredients and then neutralized. 
     Preferably the neutralisation step (III) is performed using a basic salt. Preferably the basic salt having a cation selected from the group consisting of alkali metal, alkaline earth metal, ammonium, substituted ammonium, and mixtures thereof and an anion selected from hydroxide, oxide, carbonate, silicate, phosphate and mixtures thereof More preferably the basic salt is selected from the group consisting of sodium hydroxide, potassium hydroxide, magnesium hydroxide, calcium hydroxide, ammonium hydroxide, and mixtures thereof. 
     The processes are tolerant of variation, for example conventional steps can be added before, in parallel with, or after the outlined steps (I), (II) and (III). This is especially the case for accomodating the use of hydrotropes or their precursors.

     Substantially Dimethyl Branched Olefin Mixture With Randomized Branching 
     (A Branched Olefin Mixture Which is an Alkylating Agent for Preparing Modified Alkylbenzenes in Accordance With the Invention) 
     To a nitrogen blanketed, 2 L, 3-neck round bottom flask equipped with thermometer, mechanical stirrer and a Dean-Stark trap with reflux condenser is added 225 g of 4,8-dimethyl-2-nonanol (example 11), 450 g of 5,7-dimethyl-2-decanol (example 10), 225 g of 6,10-dimethyl-2-undecanol (example 9) and 180 g of a shape selective zeolite catalyst (acidic mordenite catalyst Zeocat™ FM-8/25H). With mixing, the mixture is heated (135-160° C.) to the point water and some olefin is driven off and collected in Dean-Stark trap at a moderate rate. After a few hours, the rate of water collection slows and the temperature rises to 180-195° C. where the reaction is allowed to mix for an additional 2-4 hours. The dimethyl branched olefin mixture remaining in the flask is filtered to remove the catalyst. The catalyst filter cake is slurried with 500 ml of hexane and vacuum filtered. The catalyst filter cake is washed twice with 100 ml of hexane and the filtrate concentrated by evaporation of the hexane under vacuum. The resulting product is combined with the first filtrate to give 820 g of dimethyl branched olefin mixture with randomized branching. 
     Example 13 
     Substantially Dimethyl Branched Alkylbenzene Mixture With Randomized Branching and 2/3-Phenyl Index of About 200 and a 2-Methyl-2-Phenyl Index of About 0.04 
     (A Modified Alkylbenzene Mixture in Accordance With the Invention) 
     820 g of the dimethyl branched olefin mixture of example 12 and 160 g of a shape selective zeolite catalyst (acidic beta zeolite catalyst Zeocat™ PB/H) are added to a 2 gallon stainless steel, stirred autoclave and the autoclave is sealed. The autoclave is purged twice with 80 psig N 2  and then charged to 60 psig N 2 . From outside the autoclave cell, 3000 g of benzene (contained in a isolated vessel and added by way of an isolated pumping system inside the isolated autoclave cell) is added to the autoclave. The mixture is stirred and heated to about 205° C. for about 8 hours. The autoclave is cooled to about 30° C. overnight. The valve is opened leading from the autoclave to the benzene condenser and collection tank. The autoclave is heated to about 120° C. with continuous collection of benzene. No more benzene is collected by the time the reactor reaches 120° C. and the reactor is then cooled to 40° C. The autoclave is then drained to remove the reaction mixture. The reaction mixture is filtered to remove catalyst and vacuum pulled on the mixture to remove any residual traces of benzene. The product is distilled under vacuum (1-5 mm of Hg). The dimethyl branched alkylbenzene mixture with randomized branching and 2/3-Phenyl Index of about 200 and a 2-methyl-2-phenyl index of about 0.04 is collected from 88° C.-160° C.

     Methods for Determining Compositional Parameters (2/3-phenyl Index, 2-methyl-2-phenyl Index) of Mixed Alkylbenzene/Alkylbenzenesulfonate/Alkylbenzenesulfonic Acid Systems 
     It is well known in the art to determine compositional parameters of conventional linear alkylbenzenes and/or highly branched alkylbenzenesulfonates (TPBS, ABS). See, for example Surfactant Science Series, Volume 40, Chapter 7 and Surfactant Science Series, Volume 73, Chapter 7. Typically this is done by GC and/or GC-mass spectroscopy for the alkylbenzenes and HPLC for the alkylbenzenesulfonates or sulfonic acids;  13 C. nmr is also commonly used. Another common practice is desulfonation. This permits GC and/or GC-mass spectroscopy to be used, since desulfonation converts the sulfonates or sulfonic acids to the alkylbenzenes which are tractable by such methods. 
     In general, the present invention provides unique and relatively complex mixtures of alkylbenzenes, and similarly complex surfactant mixtures of alkylbenzenesulfonates and/or alkylbenzenesulfonic acids. Compositional parameters of such compositions can be determined using variations and combinations of the art-known methods. 
     The sequence of methods to be used depends on the composition to be characterized as follows:

     Standards required for this method are 2-phenyloctane and 2-phenylpentadecane, each freshly distilled to a purity of greater than 98%. Run both standards using the conditions specified above to define the retention time for each standard. This defines a rentention time range which is the retention time range to be used for characterizing any alkylbenzenes or alkylbenzene mixtures in the context of this invention (e.g., test samples). Now run the test samples for which compositional parameters are to be determined. Test samples pass the GC test provided that greater than 90% of the total GC area percent is within the retention time range defined by the two standards. Test samples that pass the GC test can be used directly in the NMR1 and NMR2 test methods. Test samples that do not pass the GC test must be further purified by distillation until the test sample passes the GC test. 
     Desulfonation (DE) 
     The desulfonation method is a standard method described in “The Analysis of Detergents and Detergent Products” by G. F. Longman on pages 197-199. Two other useful descriptions of this standard method are given on page 230-231 of volume 40 of the Surfactant Sience Series edited by T. M. Schmitt: “Analysis of Surfactants” and on page 272 of volume 73 of the Surfactant Science Series: “Anionic Surfactants” edited by John Cross. This is an alternative method to the HPLC method, described herein, for evaluation of the branched and nonbranched alkylbenzenesulfonic acid and/or salt mixtures (Modified Alkylbenzensulfonic acid and or salt Mixtures). The method provides a means of converting the sulfonic acid and/or salt mixture into branched and nonbranched alkylbenzene mixtures which can then be analyzed by means of the GC and NMR methods NMR1 and NMR2 described herein.

     Procedure 
     A. Preparation of HPLC Mobile Phase 
     1. Mobile phase A 
     a) Weigh 11.690 g sodium chloride and transfer to a 2000 mL volumetric flask. Dissolve in 200 mL HPLC grade water. 
     b) Add 800 mL of acetonitrile and mix. Dilute to volume after solution comes to room temperature. This prepares a solution of 100 mM NaCl/40% ACN. 
     c) Filter through an LC eluent membrane filter and degas prior to use. 
     2. Mobile phase B—Prepare 2000 mL of 60% acetonitrile in HPLC grade water. Filter through an LC eluent membrane filter and degas prior to use. 
     B. C8 and C15 Internal Standard Solution 
     1. Weigh 0.050 g of a 2-phenyloctylbenzenesulfonate and 0.050g of 2-Phenylpentadecanesulfonate standards and quantitatively transfer to a 100 mL volumetric flask. 
     2. Dissolve with 30 mL ACN and dilute to volume with HPLC grade water. This prepares ca. 1500 ppm solution of the mixed standard. 
     C. Sample Solutions 
     1. Wash Solutions—Transfer 250 μL of the standard solution to a 1 mL autosampler vial and add 750 μL of the wash solution. Cap and place in the autosampler tray. 
     2. Alkylbenzenesulfonic acid or Alkylbenzenesulfonate—Weigh 0.10 g of the alkylbenzenesulfonic acid or salt and quantitatively transfer to a 100 mL volumetric flask. Dissolve with 30 mL ACN and dilute to volume with HPLC grade water. Transfer 250 μL of the standard solution to a 1 mL autosampler vial and add 750 μL of the sample solution. Cap and place in the autosampler tray. If solution is excessively turbid, filter through 0.45 μm membrane before transferring to auto-sampler vial. Cap and place in the auto-sampler tray. 
     D. HPLC System 
     1. Prime HPLC pump with mobile phase. Install column and column inlet filter and equilibrate with eluent (0.3 mL/min for at least 1 hr.).

     3. The column should be washed with 100% water followed by 100% acetonitrile and stored in 80/20 ACN/water. 
     The HPLC elution time of the 2-phenyloctylbenzenesulfonate defines the lower limit and the elution time of the 2-phenylpentadecanesulfonate standard defines the upper limit of the HPLC analysis relating to the alkylbenzenesulfonic acid/salt mixture of the invention. If 90% of the alkylbenzenesulfonic acid/salt mixture components have retention times within the range of the above standards then the sample can be further defined by methods NMR 3 and NMR 4. 
     If the alkylbenzenesulfonic acid/salt mixture contains 10% or more of components outside the retention limits defined by the standards then the mixture should be further purified by method HPLC-P or by DE, DIS methods. 
     HPLC Preparative (HPLC-P) 
     Alkylbenzenesulfonic acids and/or the salts which contain substantial impurities (10% or greater) are purified by preparative HPLC. See, for example Surfactant Science Series, Volume 40, Chapter 7 and Surfactant Science Series, Volume 73, Chapter 7. This is routine to one skilled in the art. A sufficient quantity should be purified to meet the requirements of the NMR 3 and NMR 4. 
     Preparative LC Method Using Mega Bond Elut Sep Pak® (HPLC-P) 
     Alkylbenzenesulfonic acids and/or the salts which contain substantial impurities (10% or greater) can also be purified by an LC method (also defined herein as HPLC-P). 
     This procedure is actually preferred over HPLC column prep purification. 
     As much as 500 mg of unpurified MLAS salts can be loaded onto a 10 g(60 ml) Mega Bond Elut Sep Pak® and with optimized chromatography the purified MLAS salt can be isolated and ready for freeze drying within 2 hours. A 100 mg sample of Modified alkylbenzenesulfonate salt can be loaded onto a 5 g(20 ml) Bond Elut Sep Pak and ready within the same amount of time.

     Sep Pak Equilibrium (Bond Elut, 5 G) 
     1. Pass 10 ml of a solution containing 25/75 H 2 O/ACN onto the sep pak by applying positive pressure with a 10 cc syringe at a rate of ˜40 drops/min. Do not allow the sep pak to go dry. 
     2. Immediately pass 10 ml (×3) of a solution containing 70/30 H 2 O/ACN in the same manner as #1. Do not allow the sep pak to go dry. Maintain a level of solution (˜1 mm) at the head of the sep pak. 
     3. The sep pak is now ready for sample loading. 
     MLAS Sample Loading/Separation and Isolation 
     4. Weigh &lt;200 mg of sample into a 1 dram vial and add 2 ml of 70/30 H 2 O/ACN. Sonicate and mix well. 
     5. Load sample onto Bond Elut and with positive pressure from a 10 cc syringe begin separation. Rinse vial with 1 ml (×2) portions of the 70/30 solution and load onto sep pak. Maintain ˜1 mm of solution at the head of the sep pak. 
     6. Pass 10 ml of 70/30 onto the Bond Elut with positive pressure from a 10 cc syringe at a rate of ˜40 drops/min. 
     7. 4. Repeat this with 3 ml and 4 ml and collect effluent if interested in impurities. 
     MLAS Isolation and Collection 
     1. Pass 10 ml of solution containing 25/75 H 2 O/ACN with positive pressure from a 10 cc syringe and collect effluent. Repeat this with another 10 ml and again with 5 ml. The isolated MLAS is now ready for freeze drying and subsequent characterization. 
     2. Rotovap until ACN is removed and freeze dry the remaining H 2 O. Sample is now ready for chromatography. 
     Note: When incorporating the Mega Bond Elut Sep Pak (10 g version) up to 500 mg of sample can be loaded onto the sep pak and with solution volume adjustments, the effluent can be ready for freeze drying within 2 hours. 
     Sep Pak Equilibration (Bond Elut, 10 G) 
     1. Pass 20 ml of a solution containing 25/75 H 2 O/ACN onto the sep pak using laboratory air or regulated cylinder air at a rate which will allow ˜40 drops/min. You can not use positive pressure from a syringe because it is not sufficient to move the solution thru the sep pak. Do not allow the sep pak to go dry. 
     2. Immediately pass 20 ml (×2) and an additional 10 ml of a solution containing 70/30 H 2 O/ACN in the same manner as #1. Do not allow the sep pak to go dry. Maintain a level of solution (˜1 mm) at the head of the sep pak. 
     3. The sep pak is now ready for sample loading. 
     MLAS Sample Loading/Separation and Isolation 
     1. Weigh &lt;500 mg of sample into a 2 dram vial and add 5 ml of 70/30 H 2 O/ACN. Sonicate and mix well. 
     2. Load sample onto Bond Elut and with positive pressure from an air source begin separation. Rinse vial with 2 ml (×2) portions of the 70/30 solution and put onto the sep pak. Maintain ˜1 mm of solution at the head of the sep pak. 
     3. Pass 20 ml of 70/30 onto the Bond Elut with positive pressure from an air source at a rate of 40 drops/min. Repeat this with 6 ml and 8 ml and collect effluent if interested in impurities. 
     MLAS Isolation and Collection 
     1. Pass 20 ml of solution containing 25/75 H 2 O/ACN with positive pressure from an air source and collect effluent. 
     2. Repeat this with another 20 ml and again with 10 ml. This isolated fraction contains the pure MLAS. 
     3. The isolated MLAS is now ready for freeze drying and subsequent characterization. 
     4. Rotovap until ACN is removed and freeze dry the remaining H 2 O. Sample is now ready for chromatography. 
     Note: Adjustments in organic modifier concentration may be necessary for optimum separation and isolation. 
     Distillation (dis) 
     A 5 liter, 3-necked round bottom flask with 24/40 joints is equipped with a magnetic stir bar. A few boiling chips (Hengar Granules, catalog #136-C.) are added to the flask. A 9½ inch long vigreux condenser with a 24/40 joint is placed in the center neck of the flask. A water cooled condenser is attached to the top of the vigreux condenser which is fitted with a calibrated thermometer. A vacuum receiving flask is attached to the end of the condenser. A glass stopper is placed in one side arm of the 5 liter flask and a calibrated thermometer in the other. The flask and the vigreux condenser are wrapped with aluminum foil. To the 5 liter flask, is added 2270 g of an alkylbenzene mixture which contains 10% or more impurities as defined by the GC method. A vacuum line leading from a vacuum pump is attached to the receiving flask. The alkylbenzene mixture in the 5 liter flask is stirred and vacuum is applied to the system. Once the maximum vacuum is reached (at least 1 inch of Hg pressure by gauge or less), the alkylbenzene mixture is heated by means of an electric heating mantle. The distillate is collected in two fractions. Fraction A is collected from about 25° C. to about 90° C. as measured by the calibrated thermometer at the top of the vigreux column. Fraction B is collected from about 90° C. to about 155° C. as measured by the calibrated thermometer at the top of the vigreux column. Fraction A and pot residues (high boiling) are discarded. Fraction B (1881 g) contains the alkylbenzene mixture of interest. The method can be sealed according to the practitioner&#39;s needs provided that sufficient quantity of the alkylbenzene mixture remains after distillation for evaluation by NMR methods NMR1 and NMR2. 
     Acidification (AC) 
     Salts of alkylbenzenesulfonic acids are acidified by common means such as reaction in a solvent with HCI or sulfuric acid or by use of an acidic resin such as Amberlyst 15. Acificication is routine to one skilled in the art. After acidifying remove all solvents, especially any moisture, so that the samples are anhydrous and solvent-free. 
     Note: For all of the below NMR test methods, the chemical shifts of the NMR spectrum are either externally or internally referenced to TMS in CDCl 3 , i.e. chloroform.

     In one embodiment of the present invention, the hard surface cleaning compositions are substantially free from alkylbenzene sulfonate surfactants other than the modified alkylbenzene sulfonate surfactant mixture. That is no alkylbenzene sulfonate surfactants other than the modified alkylbenzene sulfonate surfactant mixture are added to the detergent compositions. 
     In another embodiment of the present invention, the hard surface cleaning compositions may contain as an additional surfactant at least about 0.1%, preferably no more than about 10%, more preferably no more than about 5%, more preferably still, no more than about 1%, of a commercial C 10 -C 14  linear alkylbenzene sulfonate surfactant. It is further preferred that the commercial C 10 -C 14  linear alkylbenzene sulfonate surfactant has a 2/3 phenyl index of from 75 to 160. 
     In another embodiment of the present inventions the hard surface cleaning compositions may contain as an additional surfactant at least about 0.1%, preferably no more than about 10%, more preferably no more than about 5%, more preferably still, no more than about 1%, of a commercial highly branched alkylbenzene sulfonate surfactant. For example TPBS or tetrapropylbenzene sulfonate. 
     The present invention encompasses less preferred but sometimes useful embodiments for their normal purposes, such as the addition of useful hydrotrope precursors and/or hydrotropes, such as C 1 -C 8  alkylbenzenes, more typically toluenes, cumenes, xylenes, naphthalenes, or the sulfonated derivatives of any such materials, minor amounts of any other materials, such as tribranched alkylbenzene sulfonate surfactants, dialkylbenzenes and their derivatives, dialkyl tetralins, wetting agents, processing aids, and the like. It will be understood that, with the exception of hydrotropes, it will not be usual practice in the present invention to include any such materials. Likewise it will be understood that such materials, if and when they interfere with analytical methods, will not be included in samples of compositions used for analytical purposes. 
     Numerous variations of the present hard surface cleaning ons are useful. Such variations include: 
     the hard surface cleaning composition which is substantially free from alkylbenzene sulfonate surfactants other than said modified alkylbenzene sulfonate surfactant mixture; 
     the hard surface cleaning composition which comprises, in said component (iii), at least about 0.1%, preferably no more than about 10%, more preferably no more than about 5%, more preferably still, no more than about 1%, of a commercial C 10 -C 14  linear alkylbenzene sulfonate surfactant;

     A wide range of these co-surfactants can be used in the hard surface cleaning compositions of the present invention. A typical listing of anionic, nonionic, ampholytic and zwitterionic classes, and species of these co-surfactants, is given in U.S. Pat. No. 3,664,961 issued to Norris on May 23, 1972. Amphoteric co-surfactants are also described in detail in “Amphoteric Surfactants, Second Edition”, E. G. Lomax, Editor (published 1996, by Marcel Dekker, Inc.) 
     The hard surface cleaning compositions of the present invention will preferably comprise from about 0.001% to about 20%, preferably from about 0.1% to about 10%, by weight of co-surfactants. Selected co-surfactants are further identified as follows. 
     i) Anionic Co-surfactant 
     The optional anionic co-cosurfactant component can comprise as little as 0.001% of the compositions herein when it is present, but typically the compositions will contain from about 0.001% to about 20%, more preferably from about 0.1% to about 10%, even more preferably from about 0.1% to about 5% of anionic cosurfactant, when it is present. Suitable anionic co-surfactants for use herein include alkali metal (e.g., sodium or potassium) fatty acids, or soaps thereof, containing from about 8 to about 24, preferably from about 10 to about 20 carbon atoms. 
     The fatty acids including those used in making the soaps can be obtained from natural sources such as, for instance, plant or animal-derived glycerides (e.g., palm oil, coconut oil, babassu oil, soybean oil, castor oil, tallow, whale oil, fish oil, tallow, grease, lard and mixtures thereof). The fatty acids can also be synthetically prepared (e.g., by oxidation of petroleum stocks or by the Fischer-Tropsch process). 
     Alkali metal soaps can be made by direct saponification of fats and oils or by the neutralization of the free fatty acids which are prepared in a separate manufacturing process. Particularly useful are the sodium and potassium salts of the mixtures of fatty acids derived from coconut oil and tallow, i.e., sodium and potassium tallow and coconut soaps. 
     The term “tallow” is used herein in connection with fatty acid mixtures which typically have an approximate carbon chain length distribution of 2.5% C14, 29% C16, 23% C18, 2% palmitoleic, 41.5% oleic and 3% linoleic (the first three fatty acids listed are saturated). Other mixtures with similar distribution, such as the fatty acids derived from various animal tallows and lard, are also included within the term tallow. The tallow can also be hardened (i.e., hydrogenated) to convert part or all of the unsaturated fatty acid moieties to saturated fatty acid moieties. 
     When the term “coconut” is used herein it refers to fatty acid mixtures which typically have an approximate carbon chain length distribution of about 8% C8, 7% C10, 48% C12, 17% C14, 9% C16, 2% C18, 7% oleic, and 2% linoleic (the first six fatty acids listed being saturated). Other sources having similar carbon chain length distribution such as palm kernel oil and babassu oil are included with the term coconut oil. 
     Other suitable anionic co-surfactants for use herein include water-soluble salts, particularly the alkali metal salts, of organic sulfuric reaction products having in the molecular structure an alkyl radical containing from about 8 to about 22 carbon atoms and a radical selected from the group consisting of sulfonic acid and sulfuric acid ester radicals. Important examples of these synthetic detergents are the sodium, ammonium or potassium alkyl sulfates, especially those obtained by sulfating the higher alcohols produced by reducing the glycerides of tallow or coconut oil; sodium or potassium alkyl benzene sulfonates, in which the alkyl group contains from about 9 to about 15 carbon atoms, especially those of the types described in U.S. Pat. Nos. 2,220,099 and 2,477,383, incorporated herein by reference; sodium alkyl glyceryl ether sulfonates, especially those ethers of the higher alcohols derived from tallow and coconut oil; sodium coconut oil fatty acid monoglyceride sulfates and sulfonates; alkyl benzene sulfates and sulfonates, alkyl ether sulfates, paraffin sulfonates, sulfonates of fatty acids and of fatty acid esters, sulpho succinates, sarcosinates, sodium or potassium salts of sulfuric acid esters of the reaction product of one mole of a higher fatty alcohol (e.g., tallow or coconut oil alcohols) and about three moles of ethylene oxide; sodium or potassium salts of alkyl phenol ethylene oxide ether sulfates with about four units of ethylene oxide per molecule and in which the alkyl radicals contain about 9 carbon atoms; the reaction product of fatty acids esterified with isothionic acid and neutralized with sodium hydroxide where, for example, the fatty acids are derived from coconut oil; sodium or potassium salts of fatty acid amide of a methyl taurine in which the fatty acids, for example, are derived from coconut oil; and others known in the art, a number being specifically set forth in U.S. Pat. Nos. 2,486,921, 2,486,922 and 2,396,278, incorporated herein by reference. 
     The anionic co-surfactants can also be used in the form of their salts, including sodium, potassium, magnesium, ammonium and alkanol/alkyl ammonium salts. 
     The hard surface cleaning compositions of the present invention may additionally contain one of two sulfosuccinamate co-surfactant. The two possible sulfosuccinamates are: 
     i) N-2-ethylhexyl sulfosuccinamate:                    
      wherein R 1  and R 2  are selected from hydrogen or the moiety —SO 3 M 2 , provided however that R 1 and R 2  are not the same, that is when R 1  is hydrogen, R 2  must be —SO 3 M 2  and vice versa. M and M 2  are independently selected from hydrogen or a salt forming cation. Three carbon atoms in the above molecule are chiral centers, that is they individually have the capacity to form optical isomers or enantiomers. In addition, when two or more of these chiral carbons are taken together they may form diasteriomeric pairs or combinations. For the purposes of the present invention the sulfosuccinamates are drawn such that each chiral center is shown in its racemic form. For the purposes of the present invention all isomeric forms of the sulfosuccinamate are suitable for use in the compositions of the present invention. 
     M and M 2  may be hydrogen or a salt forming cation depending upon the method of synthesis chosen and the pH of the final hard surface cleaner. Examples of salt forming cations are lithium, sodium, potassium, calcium, magnesium, quaternary alkyl amines having the formula                    
     wherein R 4 , R 5 , R 6  and R 7  are independently hydrogen, C 1 -C 22  alkylene, C 4 -C 22  branched alkylene, C 1 -C 6  alkanol, C 1 -C 22  alkenylene, C 4 -C 22  branched alkenylene, and mixtures thereof. A different salt forming cation may be chosen for the carboxylate moiety (—CO 2 —) than is chosen for the sulfonate moiety (—SO 3 —). Preferred cations are ammonium (R 4 , R 5 , R 6  and R 7  equal hydrogen), sodium, potassium, mono-, di-, and trialkanol ammonium, and mixtures thereof. The monoalkanol ammonium compounds of the present invention have R 4  equal to C 1 -C 6  alkanol, R 5 , R 6  and R 7  equal to hydrogen; dialkanol ammonium compounds of the present invention have R 4  and R 5  equal to C 1 -C 6  alkanol, R 6  and R 7 equal to hydrogen; trialkanol ammonium compounds of the present invention have R 4 , R 5  and R 6  equal to C 1 -C 6  alkanol, R 7  equal to hydrogen. Preferred alkanol ammonium salts of the present invention are the mono-, di- and tri- quaternary ammonium compounds having the formulas: 
     
       
         H 3 N + CH 2 CH 2 OH, H 2 N + (CH 2 CH 2 OH) 2 , HN + (CH 2 CH 2 OH) 3 . 
       
     
     Preferred M and M 2  are hydrogen, sodium, potassium and the C 2  alkanol ammonium salts listed above; most preferred are hydrogen and sodium. 
     Another group of anionic co-surfactants which can be used in the hard surface cleansing compositions of the present invention have the generic formula: 
     
       
         R 9 —(R 10 ) 0-1 —SO 3   (−) M (+)   
       
     
     wherein R 9  is a C 6 -C 20  alkyl chain, preferably a C 8 -C 16  alkyl chain; R 10 , when present, is a C 6 -C 20  alkylene chain, preferably a C 8 -C 16  alkylene chain, a C 6 H 4  phenylene group, or O; and M is the same as before. 
     Typical of these are the alkyl- and alkylethoxylate-(polyethoxylate) sulfates, paraffin sulfonates, olefin sulfonates, alkoxylated (especially ethoxylated) alcohols and alkyl phenols, alkyl phenol sulfonates, alpha-sulfonates of fatty acids and of fatty acid esters, and the like, which are well-known from the detergency art. When the pH is above about 9.5, co-surfactants that are amphoteric at a lower pH are desirable anionic co-cosurfactants. For example, co-surfactants which are C 12 -C 18  acylamido alkylene amino alkylene sulfonates, e.g., compounds having the formula R—C(O)—NH—(C 2 H 4 )—N(C 2 H 4 OH)—CH 2 CH(OH)CH 2 SO 3 M wherein R is an alkyl group containing from about 9 to about 18 carbon atoms and M is a compatible cation are desirable cosurfactants. These co-surfactants are available as Miranol® CS, OS, JS, etc. The CTFA adopted name for such co-surfactants is cocoamphohydroxypropyl sulfonate. 
     In general, anionic co-surfactants useful herein contain a hydrophobic group, typically containing an alkyl group in the C 9 -C 18  range, and, optionally, one or more linking groups such as ether or amido, preferably amido groups. The anionic detergent surfactants can be used in the form of their sodium, potassium or alkanolammonium, e.g., triethanolammonium salts. C 12 -C 18  paraffin-sulfonates and alkyl sulfates are useful anionic co-surfactants in the compositions of the present type. 
     Some other suitable anionic co-surfactants for use herein in small amounts are one or more of the following: sodium linear C 8 -C 18  alkyl benzene sulfonate (LAS), particularly C 11 -C 12  LAS; the sodium salt of a coconut alkyl ether sulfate containing 3 moles of ethylene oxide; the adduct of a random secondary alcohol having a range of alkyl chain lengths of from 11 to 15 carbon atoms and an average of 2 to 10 ethylene oxide moieties, several commercially available examples of which are Tergitol® 15-S-3, Tergitol 15-S-5, Tergitol 15-S-7, and Tergitol 15-S-9, all available from Union Carbide Corporation; the sodium and potassium salts of coconut fatty acids (coconut soaps); the condensation product of a straight-chain primary alcohol containing from about 8 carbons to about 16 carbon atoms and having an average carbon chain length of from about 10 to about 12 carbon atoms with from about 4 to about 8 moles of ethylene oxide per mole of alcohol; an amide having one of the preferred formulas:                    
     wherein R 7  is a straight-chain alkyl group containing from about 7 to about 15 carbon atoms and having an average carbon chain length of from about 9 to about 13 carbon atoms and wherein each R 8  is a hydroxy alkyl group containing from 1 to about 3 carbon atoms. Another suitable class of surfactants are the fluorocarbon surfactants, examples of which are FC-129®, a potassium fluorinated alkylcarboxylate and FC-170-C®, a mixture of fluorinated alkyl polyoxyethylene ethanols, both available from 3M Corporation, as well as the Zonyl® fluorosurfactants, available from DuPont Corporation. It is understood that mixtures of various anionic co-surfactants can be used. 
     Other typical optional anionic co-surfactants are the alkyl- and alkyl(polyethoxylate) sulfates, paraffin sulfonates, olefin sulfonates, alpha-sulfonates of fatty acids and of fatty acid esters, and the like, which are well known from the detergency art. In general, such detergent surfactants contain an alkyl group in the C 9-22  preferably C 10-18 , more preferably C 12-16 , range. The anionic co-surfactants can be used in the form of their sodium, potassium or alkanolammonium, e.g., triethanolammonium salts. 
     A detailed listing of suitable anionic co-surfactants, of the above types, for the hard surface cleaning compositions herein can be found in U.S. Pat. Nos. 4,557,853, and 3,929,678 incorporated by reference hereinbefore. Commercial sources of such surfactants can be found in McCutcheon&#39;s EMULSIFIERS AND DETERGENTS, North American Edition, 1997, McCutcheon Division, MC Publishing Company, also incorporated hereinbefore by reference. 
     Anionic co-surfactants suitable for use in the hard surface cleaning compositions include alkyl and alkyl ether sulfates. These materials have the respective formulae ROSO 3 M and RO(C 2 H 4 O) x SO 3 M, wherein R is alkyl or alkenyl of from about 8 to about 30 carbon atoms, x is 0.01 to 10, and M is a cation such as ammonium, alkanolamines, such as triethanolamine, monovalent metals, such as sodium and potassium, and polyvalent metal cations, such as magnesium, and calcium. The cation M, of the anionic co-surfactant should be chosen such that the anionic co-surfactant component is water soluble. Solubility will depend upon the particular anionic co-surfactants and cations chosen. 
     Preferably, R has from about 12 to about 18 carbon atoms in both the alkyl and alkyl ether sulfates. The alkyl ether sulfates are typically made as condensation products of ethylene oxide and monohydric alcohols having from about 8 to about 24 carbon atoms. The alcohols can be derived from fats, e.g., coconut oil or tallow, or can be synthetic. Lauryl alcohol and straight chain alcohols derived from coconut oil are preferred herein. Such alcohols are reacted with between about 0 and about 10, and especially about 3, molar proportions of ethylene oxide and the resulting mixture of molecular species having, for example, an average of 3 moles of ethylene oxide per mole of alcohol, is sulfated and neutralized. 
     Specific examples of alkyl ether sulfates which may be used in the hard surface cleaning compositions of the present invention are sodium and ammonium salts of coconut alkyl triethylene glycol ether sulfate; tallow alkyl triethylene glycol ether sulfate, and tallow alkyl hexaoxyethylene sulfate. Highly preferred alkyl ether sulfates are those comprising a mixture of individual compounds, said mixture having an average alkyl chain length of from about 10 to about 16 carbon atoms and an average degree of ethoxylation of from about 1 to about 4 moles of ethylene oxide. 
     Other suitable anionic co-surfactants are the water-soluble salts of organic, sulfuric acid reaction products of the general formula [R 1 —SO 3 —M ] where R 1  is selected from the group consisting of a straight or branched chain, saturated aliphatic hydrocarbon radical having from about 8 to about 24, preferably about 10 to about 18, carbon atoms; and M is a cation, as previously described, subject to the same limitations regarding polyvalent metal cations as previously discussed. Examples of such co-surfactants are the salts of an organic sulfuric acid reaction product of a hydrocarbon of the methane series, including iso-, neo-, and n-paraffins, having about 8 to about 24 carbon atoms, preferably about 12 to about 18 carbon atoms and a sulfonating agent, e.g., SO 3 , H 2 SO 4 , obtained according to known sulfonation methods, including bleaching and hydrolysis. Preferred are alkali metal and ammonium sulfonated C 10-18  n-paraffins.

     Other suitable anionic co-surfactants include olefin sulfonates having about 10 to about 24 carbon atoms. The term “olefin sulfonates” is used herein to mean compounds which can be produced by the sulfonation of alpha-olefins by means of uncomplexed sulfur trioxide, followed by neutralization of the acid reaction mixture in conditions such that any sulfones which have been formed in the reaction are hydrolyzed to give the corresponding hydroxy-alkanesulfonates. The sulfur trioxide can be liquid or gaseous, and is usually, but not necessarily, diluted by inert diluents, for example by liquid SO 2 , chlorinated hydrocarbons, etc., when used in the liquid form, or by air, nitrogen, gaseous SO 2 , etc., when used in the gaseous form. 
     The alpha-olefins from which the olefin sulfonates are derived are mono-olefins having about 12 to about 24 carbon atoms, preferably about 14 to about 16 carbon atoms. Preferably, they are straight chain olefins. 
     In addition to the true alkene sulfonates and a proportion of hydroxy-alkanesulfonates, the olefin sulfonates can contain minor amounts of other materials, such as alkene disulfonates depending upon the reaction conditions, proportion of reactants, the nature of the starting olefins and impurities in the olefin stock and side reactions during the sulfonation process. 
     A specific alpha-olefin sulfonate mixture of the above type is described more fully in the U.S. Pat. No. 3,332,880, which description is incorporated herein by reference.

     ii) Nonionic; 
     The nonionic co-surfactant component can comprise as little as 0.01% of the compositions herein, especially when used with another co-surfactant, but typically the compositions will contain from about 0.5% to about 10%, more preferably from about 1% to about 5%, of nonionic co-surfactant.

     As an optional component, component (b)(ii), the compositions herein may additionally comprise a hydrophilic nonionic co-surfactant, or mixtures thereof. Suitable hydrophilic nonionic co-surfactants for use herein include alkoxylated alcohols, preferably ethoxylated alcohols. Such co-surfactants can be represented by the formula CxEOyH, where C symbolizes the hydrocarbon chain of the alcohol starting material, x represents the length of its hydrocarbon chain. EO represents ethoxy groups and y represents the average degree of ethoxylation, i.e. the average number of moles of ethoxy groups per mole of alcohol. Suitable hydrophilic nonionic co-surfactants for use herein include those where x is of from 9 to 18, preferably 9 to 14, and average y is of from 8 to 30, preferably 10 to 20 Also suitable hydrophilic nonionic co-surfactants are ethoxylated and propoxylated alcohols which can be represented by the formula CxPOyEOy′, where x is as above, and (y+y′) is as y above. 
     As an optional component, the compositions herein may additionally contain a hydrophobic nonionic co-surfactant (b)(ii), or mixtures thereof. Suitable hydrophobic nonionic co-surfactants for use herein include alkoxylated alcohols, preferably ethoxylated alcohols. Such co-surfactants can be represented by the formula CxEOyH, where C symbolizes the hydrocarbon chain of the alcohol starting material, x represents the length of its hydrocarbon chain.

Suitable hydrophobic nonionic co-surfactants for use herein include those where x is of from 9 to 18, preferably 9 to 16, and y is of from 2 to 7, preferably 4 to 7. Suitable hydrophobic nonionic co-surfactants also include ethoxylated and propoxylated alcohols which can be represented by the formula CxPOyEOy′, where x is as above x and where (y+y′) is as y above. The compositions herein can comprise mixtures of such hydrophobic nonionics, and when present, the compositions may comprise from 1% to 20%, preferably from 3% to 15% by weight of the total composition of such hydrophobic nonionic co-surfactants, or mixtures thereof. 
     Another type of suitable nonionic co-surfactants for use herein include a class of compounds which may be broadly defined as compounds produced by the condensation of alkylene oxide groups (hydrophilic in nature) with an organic hydrophobic compound, which may be branched or linear aliphatic (e.g. Guerbet or secondary alcohols) or alkyl aromatic in nature. The length of the hydrophilic or polyoxyalkylene radical which is condensed with any particular hydrophobic group can be readily adjusted to yield a water-soluble compound having the desired degree of balance between hydrophilic and hydrophobic elements. 
     For example, a well-known class of nonionic synthetic is made available on the market under the trade name “Pluronic”. These compounds are formed by condensing ethylene oxide with an hydrophobic base formed by the condensation of propylene oxide with propylene glycol. The hydrophobic portion of the molecule which, of course, exhibits water-insolubility has a molecular weight of from about 1500 to 1800. The addition of polyoxyethylene radicals to this hydrophobic portion tends to increase the water-solubility of the molecule as a whole and the liquid character of the products is retained up to the point where polyoxyethylene content is about 50% of the total weight of the condensation product. 
     Other suitable nonionic synthetic co-surfactants include 
     (i) The polyethylene oxide condensates of alkyl phenols, e.g., the condensation products of alkyl phenols having an alkyl group containing from about 6 to 12 carbon atoms in either a straight chain or branched chain configuration, with ethylene oxide, the said ethylenc oxide being present in amounts equal to 10 to 25 moles of ethylene oxide per mole of alkyl phenol. The alkyl substituent in such compounds may be derived from polymerized propylene, diisobutylene, octane, and nonane; 
     (ii) Those derived from the condensation of ethylene oxide with the product resulting from the reaction of propylene oxide and ethylene diamine products which may be varied in composition depending upon the balance between the hydrophobic and hydrophilic elements which is desired. Examples are compounds containing from about 40% to about 80% polyoxyethylene by weight and having a molecular weight of from about 5000 to about 11000 resulting from the reaction of ethylene oxide groups with a hydrophobic base constituted of the reaction product of ethylene diamine and excess propylene oxide, said base having a molecular weight of the order of 2500 to 3000; 
     (iii) The condensation product of aliphatic alcohols having from 8 to 18 carbon atoms, in either straight chain or branched chain configuration, with ethylene oxide, e.g., a coconut alcohol ethylene oxide condensate having from 10 to 30 moles of ethylene oxide per mole of coconut alcohol, the coconut alcohol fraction having from 10 to 14 carbon atoms; 
     (iv) Trialkyl amine oxides and trialkyl phosphine oxides wherein one alkyl group ranges from 10 to 18 carbon atoms and two alkyl groups range from 1 to 3 carbon atoms; the alkyl groups can contain hydroxy substituents; specific examples are dodecyl di(2-hydroxyethyl)amine oxide and tetradecyl dimethyl phosphine oxide. 
     Also useful as a nonionic co-surfactant are the alkylpolysaccharides disclosed in U.S. Pat. No. 4,565,647, Llenado, issued Jan. 21, 1986, having a hydrophobic group containing from about 6 to about 30 carbon atoms, preferably from about 10 to about 16 carbon atoms and polysaccharide, e.g., a polyglycoside, hydrophilic group containing from about 1.3 to about 10, preferably from about 1.3 to about 3, most preferably from about 1.3 to about 2.7 saccharide units. Any reducing saccharide containing 5 or 6 carbon atoms can be used, e.g., glucose, galactose, and galactosyl moieties can be substituted for the glucosyl moieties. (Optionally the hydrophobic group is attached at the 2-, 3-, 4-, etc. positions thus giving a glucose or galactose as opposed to a glucoside or galactoside.) The intersaccharide bonds can be, e.g., between the one position of the additional saccharide units and the 2-, 3-, 4-, and/or 6-positions of the preceding saccharide units. 
     Optionally there can be a polyalkkyleneoxide chain joining the hydrophobic moiety and the polysaccharide moiety. The preferred alkyleneoxide is ethylene oxide. Typical hydrophobic groups include alkyl groups, either saturated or unsaturated, branched or unbranched containing from about 8 to about 18, preferably from about 10 to about 16, carbon atoms. Preferably, the alkyl group can contain up to about 3 hydroxy groups and/or the polyalkyleneoxide chain can contain up to about 10, preferably less than 5, alkyleneoxide moieties. Suitable alkyl polysaccharides are octyl, nonyldecyl, undecyldodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, and octadecyl, di-, tri-, tetra-, penta-, and hexaglucosides, galactosides, lactosides, glucoses, fructosides, fructoses and/or galactoses. Suitable mixtures include coconut alkyl, di-, tri-, tetra-, and pentaglucosides and tallow alkyl tetra-, penta-, and hexaglucosides. 
     The preferred alkylpolyglycosides have the formula: 
     
       
         R 2 O(C n H 2n O) t (glucosyl) x   
       
     
     wherein R 2  is selected from the group consisting of alkyl, alkylphenyl, hydroxyalkyl, hydroxyalkylphenyl, and mixtures thereof in which the alkyl groups contain from about 10 to about 18, preferably from about 12 to about 14, carbon atoms; n is 2 or 3, preferably 2; t is from 0 to about 10, preferably 0; and x is from about 1.3 to about 10, preferably from about 1.3 to about 3, most preferably from about 1.3 to about 2.7. The glycosyl is preferably derived from glucose. To prepare these compounds, the alcohol or alkylpolyethoxy alcohol is formed first and then reacted with glucose, or a source of glucose, to form the glucoside (attachment at the 1-position). The additional glycosyl units can then be attached between their 1-position and the preceding glycosyl units 2-, 3-, 4- and/or 6-position, preferably predominately the 2-position. 
     The condensation products of ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol are also suitable for use herein. The hydrophobic portion of these compounds will preferably have a molecular weight of from about 1500 to about 1800 and will exhibit water insolubility. The addition of polyoxyethylene moieties to this hydrophobic portion tends to increase the water solubility of the molecule as a whole, and the liquid character of the product is retained up to the point where the polyoxyethylene content is about 50% of the total weight of the condensation product, which corresponds to condensation with up to about 40 moles of ethylene oxide. Examples of compounds of this type include certain of the commercially available Pluronic™ co-surfactants, marketed by BASF. 
     Also suitable for use as nonionic co-surfactants herein are the condensation products of ethylene oxide with the product resulting from the reaction of propylene oxide and ethylenediamine.

This hydrophobic moiety is condensed with ethylene oxide to the extent that the condensation product contains from about 40% to about 80% by weight of polyoxyethylene and has a molecular weight of from about 5000 to about 11000.

     wherein x is from about 6 to about 12, preferably from about 8 to about 10; y is from about 3.5 to about 10, preferably from about 4 to about 7. For the purposes of the present invention the index y refers to the average degree of ethoxylation obtained when contacting a suitable alcohol with a source of ethyleneoxy moieties, and therefore represents all fractional parts within the range 3.5 to 10.

     Examples of suitable cationic co-surfactants are described in following documents, all of which are incorporated by reference herein in their entirety: M.C. Publishing Co., McCutcheon&#39;s, Detergents &amp; Emulsifiers, (North American edition 1997); Schwartz, et al., Surface Active Agents, Their Chemistry and Technology, New York: Interscience Publishers, 1949; U.S. Pat. Nos. 3,155,591; 3,929,678; 3,959,461; 4,387,090 and 4,228,044. 
     Examples of suitable cationic co-surfactants are those corresponding to the general formula:                    
     wherein R 1 , R 2 , R 3 , and R4 are independently selected from an aliphatic group of from 1 to about 22 carbon atoms or an aromatic, alkoxy, polyoxyalkylene, alkylamido, hydroxyalkyl, aryl or alkylaryl group having up to about 22 carbon atoms; and X is a salt-forming anion such as those selected from halogen, (e.g. chloride, bromide), acetate, citrate, lactate, glycolate, phosphate nitrate, sulfate, and alkylsulfate radicals. The aliphatic groups can contain, in addition to carbon and hydrogen atoms, ether linkages, and other groups such as amino groups. The longer chain aliphatic groups, e.g., those of about 12 carbons, or higher, can be saturated or unsaturated. Preferred is when R 1 , R 2 , R 3 , and R 4  are independently selected from C1 to about C22 alkyl. Especially preferred are cationic materials containing two long alkyl chains and two short alkyl chains or those containing one long alkyl chain and three short alkyl chains. The long alkyl chains in the compounds described in the previous sentence have from about 12 to about 22 carbon atoms, preferably from about 16 to about 22 carbon atoms, and the short alkyl chains in the compounds described in the previous sentence have from 1 to about 3 carbon atoms, preferably from 1 to about 2 carbon atoms. 
     iv) Ampohteric;(Non-zwitterionic) 
     The hard surface cleaning compositions of the present invention may also optionally contain a amphoteric co-surfactant. The amount of amphoteric co-surfactant, when present in the composition can be from about 0.001% to about 10%, preferably from about 0.1% to about 5%, more preferably 0.1% to about 2% by weight. These co-surfactants are similar to the zwitterionic co-surfactants, but the surfactant characteristic of the co-surfactant changes with changes with changes in pH. At one pH it is cationic at another it is anionic. 
     Amphoteric and ampholytic co-surfactants which can be either cationic or anionic depending upon the pH of the system are represented by co-surfactants such as dodecylbeta-alanine, N-alkyltaurines such as the one prepared by reacting dodecylamine with sodium isethionate according to the teaching of U.S. Pat. No. 2,658,072, N-higher alkylaspartic acids such as those produced according to the teaching of U.S. Pat. No. 2,438,091, and the products sold under the trade name “Miranol”, and described in U.S. Pat. No. 2,528,378, said patents being incorporated herein by reference. 
     Additional amphoteric co-surfactants and listings of their commercial sources can be found in McCutcheon&#39;s Detergents and Emulsifiers, North American Ed. 1997, incorporated herein by reference. 
     The hard surface cleaning compositions herein may optionally contain from about 0.001% to about 1%, preferably from about 0.01% to about 0.5%, more preferably from about 0.02% to about 0.2%, and even more preferably from about 0.03% to about 0.08%, of C 6-10  short chain amphocarboxylate co-surfactant. It has been found that these amphocarboxylate, and, especially glycinate, co-surfactants provide good cleaning with superior filming/streaking for hard surface cleaning compositions that are used to clean both glass and/or relatively hard-to-remove soils. Despite the short chain, the detergency is good and the short chains provide improved filming/streaking, even as compared to most of the zwitterionic co-surfactants described hereinafter. Depending upon the level of cleaning desired and/or the amount of hydrophobic material in the composition that needs to be solubilized, one can either use only the amphocarboxylate co-surfactant, or can combine it with other co-surfactant, preferably zwitterionic co-surfactants. 
     The “amphocarboxylate” co-surfactants herein preferably have the generic formula: 
     
       
         RN(R 1 )(CH 2 ) n N(R 2 )(CH 2 ) p C(O)OM 
       
     
     wherein R is a C 6-10  hydrophobic moiety, typically a fatty acyl moiety containing from about 6 to about 10 carbon atoms which, in combination with the nitrogen atom forms an amido group, R 1  is hydrogen (preferably) or a C 1-2  alkyl group, R 2  is a C 1-3  alkyl or, substituted C 1-3  alkyl, e.g., hydroxy substituted or carboxy methoxy substituted, preferably, hydroxy ethyl, each n is an integer from 1 to 3, each p is an integer from 1 to 2, preferably 1, and each M is a water-soluble cation, typically an alkali metal, ammonium, and/or alkanolammonium cation. Such co-surfactants are available, for example: from Witco under the trade name Rewoteric AM-V®), having the formula 
     
       
         C 7 H 1 5 C(O)NH(CH 2 ) 2 N(CH 2 CH 2 OH)CH 2 C(O)O (−) Na (+) ; 
       
     
     Mona Industries, under the trade name Monateric 1000®, having the formula 
     
       
         C 7 H 15 C(O)NH(CH 2 ) 2 N(CH 2 CH 2 OH)CH 2 CH 2 C(O)O (−) Na (+) ; 
       
     
     and Lonza under the trade name Amphoterge KJ-2®, having the formula 
     
       
         C 7,9 ,H 15,19 C(O)NH(CH 2 ) 2 N(CH 2 CH 2 OCH 2 C(O)O (−) Na (+) )CH 2 C(O)O (−) Na (+) . 
       
     
     One suitable amphoteric co-surfactant is a C 8-14  amidoalkylene glycinate co-surfactant. These co-surfactants are essentially cationic at the acid pH. 
     The glycinate co-surfactants herein preferably have the generic formula, as an acid, of:                    
     wherein 
     RC(O) is a C 8-14 , preferably C 8-10 , hydrophobic fatty acyl moiety containing from about 8 to about 14, preferably from about 8 to about 10, carbon atoms which, in combination with the nitrogen atom, forms an amido group, each n is from 1 to 3, and each R 1  is hydrogen (preferably) or a C 1-2  alkyl or hydroxy alkyl group. Such co-surfactants are available, e.g., in the salt form, for example, from Sherex under the trade name Rewoteric AM-V, having the formula: 
     
       
         C 7 C(O)NH(CH 2 ) 2 N(CH 2 CH 2 OH)CH 2 C(O)O (−) Na (+) . 
       
     
     Not all amphoteric co-surfactants are preferred. Longer chain glycinates and similar substituted amino propionates provide a much lower level of cleaning. Such propionates are available as, e.g., salts from Mona Industries, under the trade name Monateric 1000, having the formula: 
     
       
         C 7 C(O)NH(CH 2 ) 2 N(CH 2 CH 2 OH)CH 2 CH 2 C(O)O (−) Na (+) . 
       
     
     Cocoyl amido ethyleneamine-N-(hydroxyethyl)-2-hydroxypropyl-1-sulfonate (Miranol CS); C 8-10  fatty acyl amidoethyleneamine-N-(methyl)ethyl sulfonate; and analogs and homologs thereof, as their water-soluble salts, or acids, are amphoterics that provide good cleaning. Optionally, these amphoterics may be combined with short chain nonionic co-surfactants to minimize sudsing. 
     Examples of other suitable amphoteric (non-zwitterionic) co-surfactants include: 
     cocoylamido ethyleneamine-N-(methyl)-acetates; 
     cocoylamido ethyleneamine-N-(hydroxyethyl)-acetates; 
     cocoylamido propyl amine-N-(hydroxyethyl)-acetates; and 
     analogs and homologs thereof, as their water-soluble salts, or acids, are suitable. 
     Amphoteric co-surfactants suitable for use in the hard surface cleaning compositions include the derivatives of aliphatic secondary and tertiary amines in which the aliphatic radical is straight or branched and one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate. 
     v) Zwitterionic 
     The level of zwitterionic co-surfactant, when present in the composition, is typically from about 0.001% to about 10%, preferably from about 0.01% to about 6%, more preferably from about 1% to about 5%. Some suitable zwitterionic co-surfactants which can be used herein comprise the betaine and betaine-like co-surfactants wherein the molecule contains both basic and acidic groups which form an inner salt giving the molecule both cationic and anionic hydrophilic groups over a broad range of pH values. Some common examples of these are described in U.S. Pat. Nos. 2,082,275, 2,702,279 and 2,255,082, incorporated herein by reference. One of the preferred zwitterionic compounds have the formula                    
     wherein R1 is an alkyl radical containing from 8 to 22 carbon atoms, R2 and R3 contain from 1 to 3 carbon atoms, R4 is an alkylene chain containing from 1 to 3 carbon atoms, X is selected from the group consisting of hydrogen and a hydroxyl radical, Y is selected from the group consisting of carboxyl and sulfonyl radicals and wherein the sum of R1, R2 and R3 radicals is from 14 to 24 carbon atoms. 
     Zwitterionic co-surfactants, as mentioned hereinbefore, contain both a cationic group and an anionic group and are in substantial electrical neutrality where the number of anionic charges and cationic charges on the co-surfactant molecule are substantially the same. Zwitterionics, which typically contain both a quaternary ammonium group and an anionic group selected from sulfonate and carboxylate groups are desirable since they maintain their amphoteric character over most of the pH range of interest for cleaning hard surfaces. The sulfonate group is the preferred anionic group. 
     Preferred zwitterionic co-surfactants have the generic formula: 
     
       
         R 3 —[C(O)—N(R 4 )—(CR 5   2 ) n   1 ] m N(R 6 ) 2   (+) —(CR 5   2 ) p 1-Y (−)   
       
     
     wherein each Y is preferably a carboxylate (COO − ) or sulfonate (SO 3   − ) group, more preferably sulfonate; wherein each R 3  is a hydrocarbon, e.g., an alkyl, or alkylene, group containing from about 8 to about 20, preferably from about 10 to about 18, more preferably from about 12 to about 16 carbon atoms; wherein each (R 4 ) is either hydrogen, or a short chain alkyl, or substituted alkyl, containing from one to about four carbon atoms, preferably groups selected from the group consisting of methyl, ethyl, propyl, hydroxy substituted ethyl or propyl and mixtures thereof, preferably methyl; wherein each (R 5 ) is selected from the group consisting of hydrogen and hydroxy groups with no more than one hydroxy group in any (CR 5   2 ) p   1  group; wherein (R 6 ) is like R 4  except preferably not hydrogen; wherein m is 0 or 1; and wherein each n 1  and p 1  are an integer from 1 to about 4, preferably from 2 to about 3, more preferably about 3. The R 3  groups can be branched, unsaturated, or both and such structures can provide filming/streaking benefits, even when used as part of a mixture with straight chain alkyl R 3  groups. The R 4  groups can also be connected to form ring structures such as imidazoline, pyridine, etc. Preferred hydrocarbyl amidoalkylene sulfobetaine (HASB) co-surfactants wherein m=1 and Y is a sulfonate group provide superior grease soil removal and/or filming/streaking and/or “anti-fogging” and/or perfume solubilization properties. Such hydrocarbylamidoalkylene sulfobetaines, and, to a lesser extent hydrocarbylamidoalkylene betaines are excellent for use in hard surface cleaning compositions, especially those formulated for use on both glass and hard-to-remove soils. They are even better when used with monoethanolamine and/or specific beta-amino alkanol as disclosed herein. 
     A specific co-surfactant is a C 10-14  fatty acylamidopropylene(hydroxypropylene)sulfobetaine, e.g., the co-surfactant available from the Witco Company as a 40% active product under the trade name “REWOTERIC AM CAS Sulfobetaine®.” 
     When the zwitterionic co-surfactant is a HASB, it is preferably in the composition from about 0.02% to about 15%, more preferably from about 0.05% to about 10%. The level in the composition is dependent on the eventual level of dilution to make the wash solution. For glass cleaning, the composition, when used full strength, or wash solution containing the composition, should preferably contain from about 0.02% to about 1%, more preferably from about 0.05% to about 0.5%, more preferably from about 0.05% to about 0.25%, of co-surfactant. For removal of difficult to remove soils like grease, the level can, and should be, higher, preferably from about 0.1% to about 10%, more preferably from about 0.25% to about 2%. Concentrated products will preferably contain from about 0.2% to about 10%, more preferably from about 0.3% to about 5%. It is an advantage of the HASB zwitterionic co-surfactants that compositions containing it can be more readily diluted by consumers since it does not interact with hardness cations as readily as conventional anionic co-surfactants. Zwitterionic co-surfactants are also extremely effective at very low levels, e.g., below about 1%. 
     Other zwitterionic co-surfactants are set forth at Col. 4 of U.S. Pat. No. 4,287,080, Siklosi, incorporated herein by reference. Another detailed listing of suitable zwitterionic co-surfactants for the compositions herein can be found in U.S. Pat. No. 4,557,853, Collins, issued Dec. 10, 1985, incorporated by reference herein. Commercial sources of such co-surfactants can be found in McCutcheon&#39;s EMULSIFIERS AND DETERGENTS, North American Edition, 1997, McCutcheon Division, MC Publishing Company, also incorporated herein by reference. 
     Another preferred zwitterionic co-surfactants is: 
     
       
         R—N (+) (R 2 )(R 3 )R 4 X (−)   
       
     
     wherein R is a hydrophobic group; R 2  and R 3  are each C 1-4  alkyl, hydroxy alkyl or other substituted alkyl group which can also be joined to form ring structures with the N; R 4  is a moiety joining the cationic nitrogen atom to the hydrophilic group and is typically an alkylene, hydroxy alkylene, or polyalkoxy group containing from about one to about four carbon atoms; and X is the hydrophilic group which is preferably a carboxylate or sulfonate group. 
     Preferred hydrophobic groups R are alkyl groups containing from about 8 to about 22, preferably less than about 18, more preferably less than about 16, carbon atoms. The hydrophobic group can contain unsaturation and/or substituents and/or linking groups such as aryl groups, amido groups, ester groups, etc. In general, the simple alkyl groups are preferred for cost and stability reasons. 
     A specific “simple” zwitterionic co-surfactant is 3-(N-dodecyl-N,N-dimethyl)-2-hydroxy-propane-1-sulfonate, available from the Sherex Company under the trade name “Varion HC.” 
     Other specific zwitterionic co-surfactants have the generic formula: 
     
       
         R—C(O)—N(R 2 )—(CR 3   2 ) n —N(R 2 ) 2   (+) —(CR 3   2 ) n —SO 2   (−)   
       
     
     wherein each R is a hydrocarbon, e.g., an alkyl group containing from about 8 up to about 20, preferably up to about 18, more preferably up to about 16 carbon atoms, each (R 2 ) is either a hydrogen (when attached to the amido nitrogen), short chain alkyl or substituted alkyl containing from one to about four carbon atoms, preferably groups selected from the group consisting of methyl, ethyl, propyl, hydroxy substituted ethyl or propyl and mixtures thereof, preferably methyl, each (R 3 ) is selected from the group consisting of hydrogen and hydroxy groups, and each n is a number from 1 to about 4, preferably from 2 to about 3; more preferably about 3, with no more than about one hydroxy group in any (CR 3   2 ) moiety. The R groups can be branched and/or unsaturated, and such structures can provide spotting/filming benefits, even when used as part of a mixture with straight chain alkyl R groups. The R 2  groups can also be connected to form ring structures. A co-surfactant of this type is a C 10-14  fatty acylamidopropylene(hydroxypropylene)sulfobetaine that is available from the Sherex Company under the trade name “Varion CAS Sulfobetaine”. 
     Other zwitterionic co-surfactants useful, and, surprisingly, preferred, herein include hydrocarbyl, e.g., fatty, amidoalkylenebetaines (hereinafter also referred to as “HAB”). These co-surfactants, which are more cationic at the pH of the composition, have the generic formula: 
     
       
         R—C(O)—N(R 2 )—(CR 3   2 ) n —N(R 2 ) 2   (+) —(CR 3   2 ) n —C(O)O (−)   
       
     
     wherein each R is a hydrocarbon, e.g., an alkyl group containing from about 8 up to about 20, preferably up to about 18, more preferably up to about 16 carbon atoms, each (R 2 ) is either a hydrogen (when attached to the amido nitrogen), short chain alkyl or substituted alkyl containing from one to about four carbon atoms, preferably groups selected from the group consisting of methyl, ethyl, propyl, hydroxy substituted ethyl or propyl and mixtures thereof, preferably methyl, each (R 3 ) is selected from the group consisting of hydrogen and hydroxy groups, and each n is a number from 1 to about 4, preferably from 2 to about 3; more preferably about 3, with no more than about one hydroxy group in any (CR 3   2 ) moiety. The R groups can be branched and/or unsaturated, and such structures can provide spotting/filming benefits, even when used as part of a mixture with straight chain alkyl R groups. 
     An example of such a co-surfactant is a C 10-14  fatty acylamidopropylenebetaine available from the Miranol Company under the trade name “Mirataine CB.” 
     c) Builders 
     The level of builder can vary widely depending upon the end use of the composition and its desired physical form. When present, the compositions will preferably comprise from about 0.001% to about 10%, more preferably 0.01% to about 7%, even more preferably 0.1% to about 5% by weight of the composition of a builder. 
     Detergent builders that are efficient for hard surface cleaners and have reduced filming/streaking characteristics at the critical levels can also be present in the compositions of the invention. Addition of specific detergent builders at critical levels to the present composition further improves cleaning without the problem of filming/streaking that usually occurs when detergent builders are added to hard surface cleaners. There is no need to make a compromise between improved cleaning and acceptable filming/streaking results, which is especially important for hard surface cleaners which are also directed at cleaning glass. These compositions containing these specific additional detergent builders have exceptionally good cleaning properties. They also have exceptionally good shine properties, i.e., when used to clean glossy surfaces, without rinsing, they have much less tendency than, e.g., carbonate built products to leave a dull finish on the surface and filming/streaking. 
     Builders can optionally be included in the compositions herein to assist in controlling mineral hardness. Preferable are builders that have reduced filming/streaking characteristics at the critical levels of the compositions of the present invention. 
     Suitable builders for use herein include nitrilotriacetates (NTA), polycarboxylates, citrates, water-soluble phosphates such as tri-polyphosphate and sodium ortho-and pyro-phosphates, silicates, ethylene diamine tetraacetate (EDTA), amino-polyphosphonates (DEQUEST), ether carboxylate builders such as in EP-A-286 167, phosphates, iminodiacetic acid derivatives such as described in EP-A-317 542, EP-262 112 and EP-A-399 133, and mixtures thereof. Other suitable optional detergent builders include salts of sodium carboxymethylsuccinic acid, sodium N-(2-hydroxy-propyl)-iminodiacetic acid, and N-diethyleneglycol-N,N-diacetic acid (hereinafter DIDA).

     Suitable and preferred polycarboxylates for use herein are organic polycarboxylates where the highest LogKa, measured at 25° C./0.1M ionic strength is between 3 and 8, wherein the sum of the LogKCa+LogKMg, measured at 25° C./0.1M ionic strength is higher than 4, and wherein LogKCa=LogKMg±2 units, measured at 25° C./0.1M ionic strength. 
     Such suitable and preferred polycarboxylates include citrate and complexes of the formula 
     
       
         CH(A)(COOX)—CH(COOX)—O—CH(COOX)—CH(COOX)(B) 
       
     
     wherein A is H or OH; B is H or —O—CH(COOX)—CH 2 (COOX); and X is H or a salt-forming cation. For example, if in the above general formula A and B are both H, then the compound is oxydissuccinic acid and its water-soluble salts. If A is OH and B is H, then the compound is tartrate monosuccinic acid (TMS) and its water-soluble salts. If A is H and B is —O—CH(COOX)—CH 2 (COOX), then the compound is tartrate disuccinic acid (TDS) and its water-soluble salts. Mixtures of these builders are especially preferred for use herein. Particularly TMS to TDS, these builders are disclosed in U.S. Pat. No. 4,663,071, issued to Bush et al., on May 5, 1987.

     wherein M is hydrogen or a cation wherein the resultant salt is water-soluble, preferably an alkali metal, ammonium or substituted ammonium cation, n is from about 2 to about 15 (preferably n is from about 2 to about 10, more preferably n averages from about 2 to about 4) and each R is the same or different and selected from hydrogen, C 1-4  alkyl or C 1-4  substituted alkyl (preferably R is hydrogen). 
     Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in U.S. Pat. Nos. 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903, all of which are incorporated herein by reference.

     Polycarboxylate detergent builders useful herein, include the builders disclosed in U.S. Pat. No. 4,915,854, Mao et al., issued Apr. 10, 1990, said patent being incorporated herein by reference. 
     Also suitable for use in the hard surface cleaning compositions of the present invention are the 3,3-dicarboxy-4-oxa-1,6-hexanediotes and the related compounds disclosed in U.S. Pat. No. 4,566,984, Bush, issued Jan. 28, 1986, incorporated herein by reference. Useful succinic acid builders include the C5-C20 alkyl succinic acids and salts thereof. A particularly preferred compound of this type is dodecenylsuccinic acid. Alkyl succinic acids typically are of the general formula R—CH(COOH)CH 2 (COOH) i.e., derivatives of succinic acid, wherein R is hydrocarbon, e.g., C 10 -C 20  alkyl or alkenyl, preferably C 12 -C 16  or wherein R may be substituted with hydroxyl, sulfo, sulfoxy or sulfone substituents, all as described in the above-mentioned patents.

Specific examples of succinate builders include: laurylsuccinate, myristylsuccinate, palmitylsuccinate, 2-dodecenylsuccinate (preferred), 2-pentadecenylsuccinate, and the like. Laurylsuccinates are the preferred builders of this group, and are described in European Patent Application 86200690.5/0 200 263, published Nov. 5, 1986. 
     Examples of useful builders also include sodium and potassium carboxymethyloxymalonate, carboxymethyloxysuccinate, cis-cyclo-hexanehexacarboxylate, cis-cyclopentane-tetracarboxylate, water-soluble polyacrylates and the copolymers of maleic anhydride with vinyl methyl ether or ethylene. 
     Other suitable polycarboxylates are the polyacetal carboxylates disclosed in U.S. Pat. No. 4,144,226, Crutchfield et al., issued Mar. 13, 1979, incorporated herein by reference. These polyacetal carboxylates can be prepared by bringing together, under polymerization conditions, an ester of glyoxylic acid and a polymerization initiator. The resulting polyacetal carboxylate ester is then attached to chemically stable end groups to stabilize the polyacetal carboxylate against rapid depolymerization in alkaline solution, converted to the corresponding salt, and added to a surfactant. 
     Polycarboxylate builders are also disclosed in U.S. Pat. No. 3,308,067, Diehl, issued Mar. 7, 1967, incorporated herein by reference. Such materials include the water-soluble salts of homo- and copolymers of aliphatic carboxylic acids such as maleic acid, itaconic acid, mesaconic acid, fumaric acid, aconitic acid, citraconic acid and methylenemalonic acid. 
     Suitable polyphosphonates for use herein are the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the tripolyphosphates, pyrophosphates, and glassy polymeric meta-phosphates), phosphonates. The most preferred builder for use herein is citrate.

Suitable polyphosphates for use herein include compounds of formula X a H b PO4, where a and b are integers such that a+b=3, and a or b can be 0, or X a H b P 3 O 10  where a and b are such that a+b=5, and a or b can be 0, and where X is a suitable counterion, particularly K + , Na +  or NH4 + . 
     One important category of polycarboxylate builders encompasses the ether polycarboxylates, including oxydisuccinate, as disclosed in Berg, U.S. Pat. No. 3,128,287, issued Apr. 7, 1964, and Lamberti et al, U.S. Pat. No. 3,635,830, issued Jan. 18, 1972. See also “TMS/TDS” builders of U.S. Pat. No. 4,663,071, issued to Bush et al, on May 5, 1987. 
     Other useful builders include the ether hydroxypolycarboxylates, copolymers of maleic anhydride with ethylene or vinyl methyl ether, 1,3,5-trihydroxy benzene-2,4,6-trisulphonic acid, and carboxymethyloxysuccinic acid, the various alkali metal, ammonium and substituted ammonium salts of polyacetic acids such as ethylene-diamine tetraacetic acid and nitrilotriacetic acid, as well as polycarboxylates such as mellitic acid, succinic acid, oxydisuccinic acid, polymaleic acid, benzene 1,3,5-tricarboxylic acid, carboxymethyloxysuccinic acid, and soluble salts thereof. 
     Citrate builders, e.g., citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance due to their availability from renewable resources and their biodegradability. Oxydisuccinates are also especially useful in the compositions and combinations of the present invention. 
     A preferred polycarboxylate builder is iminodisuccinate. Other suitable polycarboxylates are disclosed in U.S. Pat. No. 4,144,226, Crutchfield et al, issued Mar. 13, 1979 and in U.S. Pat. No. 3,308,067, Diehl, issued Mar. 7, 1967. See also Diehl U.S. Pat. No. 3,723,322. 
     Other suitable builders include dicarboxylic acids having from about 2 to about 14, preferably from about 2 to about 4, carbon atoms between the carboxyl groups. Specific dicarboxylic detergent builders include succinic, glutaric, and adipic acids, and mixtures thereof. Such acids have a pK 1  of more than about 3 and have relatively high calcium salt solubilities. Substituted acids having similar properties can also be used. 
     These dicarboxylic detergent builders provide faster removal of the hard water soils, especially when the pH is between about 2 and about 4. 
     Other suitable builders that can be used include: citric acid, and, especially, builders having the generic formula: 
     
       
         R 5 —[O—CH(COOH)CH(COOH)] n R 5   
       
     
     wherein each R 5  is selected from the group consisting of H and OH and n is a number from about 2 to about 3 on the average. Other preferred detergent builders include those described in the U.S. Pat. No. 5,051,212, Culshaw and Vos, issued Sep. 24, 1991, for “Hard-Surface Cleaning Compositions,” said patent being incorporated herein by reference. 
     In addition to the above detergent builders, other detergent builders that are relatively efficient for hard surface cleaners and/or, preferably, have relatively reduced filming/streaking characteristics include the acid forms of those disclosed in U.S. Pat. No. 4,769,172, Siklosi, issued Sep. 6, 1988, and incorporated herein by reference. Still others include the chelating agents having the formula: 
     
       
         R—N(CH 2 COOM) 2   
       
     
     wherein R is selected from the group consisting of: 
     CH 2 CH 2 CH 2 OH; —CH 2 CH(OH)CH 2 ; —CH 2 CH(OH)CH 2 OH; —CH(CH 2 OH) 2 ; —CH 3 ; —CH 2 CH 2 OCH 3 ; —C(O)—CH 3 ; —CH 2 —C(O)—NH 3 ; —CH 2 CH 2 CH 2 OCH 3 ; —C(CH 2 OH) 3 ; and mixtures thereof; wherein each M is hydrogen. 
     When it is desired that the hard surface cleaning composition be acidic, i.e. pH&lt;7, and acidic builder can be used to provide the desired pH in use. However, if necessary, the composition can also contain additional buffering materials to give a pH in use of from about 1 to about 5.5, preferably from about 2 to about 4.5, more preferably from about 2 to about 4. pH is usually measured on the product. The buffer is selected from the group consisting of: mineral acids such as HCl, HNO 3 , etc. and organic acids such as acetic, etc., and mixtures thereof. The buffering material in the system is important for spotting/filming. Preferably, the compositions are substantially, or completely free of materials like oxalic acid that are typically used to provide cleaning, but which are not desirable from a safety standpoint in compositions that are to be used in the home, especially when very young children are present. 
     Divalent Metal Ions 
     The hard surface cleaning compositions may additionally contain positive divalent ions in amounts so as to saturate the builder present in the composition. This “saturation” is preferably used in hard surface cleaning compositions when the hard surface to be cleaned is a delicate surface, namely marble or lacquerd wood. See copending application Ser. No. 08/981315, to Procter &amp; Gamble, all of which is incorporated herein by reference. By “saturate”, it is meant herein that there should be enough ions to bind substantially all the builder present in the composition, i.e. at least 75% of the builder, preferably at least 80%, most preferably at least 90% or all of the builder. Thus, for a 100% saturation, the ions should be present most preferably in a molar ratio of builder ions to builder of at least X:2, where X is the maximum potential number of negative charges carried per mole of builder. For instance, if said builder is citrate, then said molar ratio should be at least 3:2, because each mole of citrate can carry 3 negative changes. For the purpose of the present invention and the amount of ions needed therein, the form in which the carboxylate or phosphate groups in the builder are present is not critical. In other words, at certain pH values between 6 to 8 where some of the carboxylate or phosphate groups in the builder are in their protonated form, the preferred X:2 ratio still applies. 
     The ions can be introduced in the compositions in any form. As far as Mg is concerned, MgCl 2  has been found to be commercially attractive. However MgSO 4 , Mg Phosphates and MgNO 3  are also suitable source of Mg ions for the compositions herein. Without wishing to be bound by theory, we speculate that the ions herein somehow prevent the builder from binding with the calcium in the marble, without preventing the builder from performing in the cleaning operation. 
     Suitable positive divalent ions for use herein include Mg 2+ , Ba 2+ , Fe 2+ , Ca 2+ , Zn 2+  and Ni 2+ . Most Preferred are Mg 2+  and Ca 2+ , or mixtures thereof. 
     d) Co-solvents 
     Optionally, the compositions of the present invention further comprise one or more co-solvents. The level of co-solvent, when present in the composition, is typically from about 0.001% to about 30%, preferably from about 0.01% to about 10%, more preferably from about 1% to about 5%. Co-solvents are broadly defined as compounds that are liquid at temperatures of 20° C.-25° C. and which are not considered to be surfactants. One of the distinguishing features is that co-solvents tend to exist as discrete entities rather than as broad mixtures of compounds. Some co-solvents which are useful in the hard surface cleaning compositions of the present invention contain from about 1 carbon atom to about 35 carbon atoms, and contain contiguous linear, branched or cyclic hydrocarbon moieties of no more than about 8 carbon atoms. Examples of suitable co-solvents for the present invention include, methanol, ethanol, propanol, isopropanol, 2-methyl pyrrolidinone, benzyl alcohol and morpholine n-oxide. Preferred among these co-solvents are methanol and isopropanol. 
     The compositions herein may additionally contain an alcohol having a hydrocarbon chain comprising 8 to 18 carbon atoms, preferably 12 to 16. The hydrocarbon chain can be branched or linear, and can be mono, di or polyalcohols. 
     The co-solvents which can be used herein include all those known to the those skilled in the art of hard-surfaces cleaner compositions. Suitable co-solvents for use herein include ethers and diethers having from 4 to 14 carbon atoms, preferably from 6 to 12 carbon atoms, and more preferably from 8 to 10 carbon atoms, glycols or alkoxylated glycols, alkoxylated aromatic alcohols, aromatic alcohols, aliphatic branched alcohols, alkoxylated aliphatic branched alcohols, alkoxylated linear C1-C5 alcohols, linear C1-C5 alcohols, C8-C14 alkyl and cycloalkyl hydrocarbons and halohydrocarbons, C6-C16 glycol ethers and mixtures thereof. 
     Suitable glycols which can be used herein are according to the formula HO—CR1R2—OH wherein R1 and R2 are independently H or a C2-C10 saturated or unsaturated aliphatic hydrocarbon chain and/or cyclic. Suitable glycols to be used herein are dodecaneglycol and/or propanediol. 
     Suitable alkoxylated glycols which can be used herein are according to the formula R—(A)n—R1—OH wherein R is H, OH, a linear saturated or unsaturated alkyl of from 1 to 20 carbon atoms, preferably from 2 to 15 and more preferably from 2 to 10, wherein R1 is H or a linear saturated or unsaturated alkyl of from 1 to 20 carbon atoms, preferably from 2 to 15 and more preferably from 2 to 10, and A is an alkoxy group preferably ethoxy, methoxy, and/or propoxy and n is from 1 to 5, preferably 1 to 2. Suitable alkoxylated glycols to be used herein are methoxy octadecanol and/or ethoxyethoxyethanol. 
     Suitable alkoxylated aromatic alcohols which can be used herein are according to the formula R (A) n —OH wherein R is an alkyl substituted or non-alkyl substituted aryl group of from 1 to 20 carbon atoms, preferably from 2 to 15 and more preferably from 2 to 10, wherein A is an alkoxy group preferably butoxy, propoxy and/or ethoxy, and n is an integer of from 1 to 5, preferably 1 to 2. Suitable alkoxylated aromatic alcohols are benzoxyethanol and/or benzoxypropanol. 
     Suitable aromatic alcohols which can be used herein are according to the formula R—OH wherein R is an alkyl substituted or non-alkyl substituted aryl group of from 1 to 20 carbon atoms, preferably from 1 to 15 and more preferably from 1 to 10. For example a suitable aromatic alcohol to be used herein is benzyl alcohol. 
     Suitable aliphatic branched alcohols which can be used herein are according to the formula R—OH wherein R is a branched saturated or unsaturated alkyl group of from 1 to 20 carbon atoms, preferably from 2 to 15 and more preferably from 5 to 12. Particularly suitable aliphatic branched alcohols to be used herein include 2-ethylbutanol and/or 2-methylbutanol. 
     Suitable alkoxylated aliphatic branched alcohols which can be used herein are according to the formula R (A) n —OH wherein R is a branched saturated or unsaturated alkyl group of from 1 to 20 carbon atoms, preferably from 2 to 15 and more preferably from 5 to 12, wherein A is an alkoxy group preferably butoxy, propoxy and/or ethoxy, and n is an integer of from 1 to 5, preferably 1 to 2. Suitable alkoxylated aliphatic branched alcohols include 1-methylpropoxyethanol and/or 2-methylbutoxyethanol. 
     Hydrophobic Co-solvent 
     Hydrophobic co-solvents are preferably used, when present in the composition, at a level of from about 0.5% to about 30%, more preferably from about 1% to about 15%, even more preferably from about 2% to about 5%. 
     In order to improve cleaning in liquid compositions, one can use a hydrophobic co-solvent that has cleaning activity. The hydrophobic co-solvents which may be employed in the hard surface cleaning compositions herein can be any of the well-known “degreasing” co-solvents commonly used in, for example, the dry cleaning industry, in the hard surface cleaner industry and the metalworking industry. 
     A useful definition of such co-solvents can be derived from the solubility parameters as set forth in “The Hoy,” a publication of Union Carbide, incorporated herein by reference. The most useful parameter appears to be the hydrogen bonding parameter which is calculated by the formula:          γ                 H     =     γ                     T        [       a   -   1     a     ]         1   /   2                         
     wherein γH is the hydrogen bonding parameter, a is the aggregation number,            (       Log                 α     =       3.39066                     T   b     /     T   c         -   0.15848   -     Log        M   d           )     ,   and                                
     γT is the solubility parameter which is obtained from the formula:          γ                 T     =       [         (       Δ                   H   25       -   RT     )        d     M     ]       1   /   2                       
     where ΔH 25  is the heat of vaporization at 25° C., R is the gas constant (1.987 cal/mole/deg), T is the absolute temperature in ° K, T b  is the boiling point in ° K, T c  is the critical temperature in ° K, d is the density in g/ml, and M is the molecular weight. 
     For the compositions herein, hydrogen bonding parameters are preferably less than about 7.7, more preferably from about 2 to about 7, or 7.7, and even more preferably from about 3 to about 6. Co-solvents with lower numbers become increasingly difficult to solubilize in the compositions and have a greater tendency to cause a haze on glass. Higher numbers require more co-solvent to provide good greasy/oily soil cleaning. 
     Many of such co-solvents comprise hydrocarbon or halogenated hydrocarbon moieties of the alkyl or cycloalkyl type, and have a boiling point well above room temperature, i.e., above about 20° C. 
     The formulator of compositions of the present type will be guided in the selection of cosolvent partly by the need to provide good grease-cutting properties, and partly by aesthetic considerations. For example, kerosene hydrocarbons function quite well for grease cutting in the present compositions, but can be malodorous. Kerosene must be exceptionally clean before it can be used, even in commercial situations. For home use, where malodors would not be tolerated, the formulator would be more likely to select co-solvents which have a relatively pleasant odor, or odors which can be reasonably modified by perfuming. 
     The C 6 -C 9  alkyl aromatic co-solvents, especially the C 6 -C 9  alkyl benzenes, preferably octyl benzene, exhibit excellent grease removal properties and have a low, pleasant odor. Likewise, the olefin co-solvents having a boiling point of at least about 100° C., especially alpha-olefins, preferably 1-decene or 1-dodecene, are excellent grease removal co-solvents. 
     Generically, glycol ethers useful herein have the formula R 11  O—(R 12 O—) m 1H wherein each R 11  is an alkyl group which contains from about 3 to about 8 carbon atoms, each R 12  is either ethylene, propylene or butylene, and m 1  is a number from 1 to about 3. The most preferred glycol ethers are selected from the group consisting of monopropyleneglycolmonopropyl ether, dipropyleneglycolmonobutyl ether, monopropyleneglycolmonobutyl ether, ethyleneglycolmonohexyl ether, ethyleneglycolmonobutyl ether, diethyleneglycolmonohexyl ether, monoethyleneglycolmonohexyl ether, monoethyleneglycolmonobutyl ether, and mixtures thereof. Some other suitable examples include, Ethylene glycol and propylene glycol ethers are commercially available from the Dow Chemical Company under the tradename “Dowanol” and from the Arco Chemical Company under the tradename “Arcosolv”. Other suitable co-solvents including mono- and di-ethylene glycol n-hexyl ether are available from the Union Carbide company. 
     A particularly preferred type of co-solvent for these hard surface cleaner compositions comprises diols having from 6 to about 16 carbon atoms in their molecular structure. Preferred diol co-solvents have a solubility in water of from about 0.1 to about 20 g/100 g of water at 20° C. The diol co-solvents in addition to good grease cutting ability, impart to the compositions an enhanced ability to remove calcium soap soils from surfaces such as bathtub and shower stall walls. These soils are particularly difficult to remove, especially for compositions which do not contain an abrasive. Other co-solvents such as benzyl alcohol, n-hexanol, and phthalic acid esters of C 1-4  alcohols can also be used. 
     Co-solvents such as pine oil, orange terpene, benzyl alcohol, n-hexanol, phthalic acid esters of C 1-4  alcohols, butoxy propanol, Butyl Carbitol® and 1-(2-n-butoxy-1-methylethoxy)propane-2-ol (also called butoxy propoxy propanol or dipropylene glycol monobutyl ether), hexyl diglycol (Hexyl Carbitol®), butyl triglycol, diols such as 2,2,4-trimethyl-1,3-pentanediol, and mixtures thereof, can be used. The butoxy-propanol co-solvent should have no more than about 20%, preferably no more than about 10%, more preferably no more than about 7%, of the secondary isomer in which the butoxy group is attached to the secondary atom of the propanol for improved odor. 
     e) Polymeric Additives 
     The hard surface cleaning compositions of the present invention may comprise from about 0.001% to about 20%, preferably from about 0.01% to about 10%, more preferably from about 0.1% to about 5%, and even more preferably from about 0.1% to about 3% of a polymeric additive. Suitable polymeric additives include: 
     1) polyalkoxylene glycol; 
     2) PVP homopolymers or copolymers thereof; 
     3) polycarboxylate; 
     4) sulfonated polystyrene polymer; and 
     5) mixtures thereof. 
     1) Polyalkoxylene Glycol 
     The hard surface cleaning compositions according to the present invention may contain an antiresoiling agent selected from the group consisting of polyalkoxylene glycol, mono- and dicapped polyalkoxylene glycol and a mixture thereof, as defined herein after. The compositions of the present invention may comprise from 0.001% to 20% by weight of the total composition of said antiresoiling agent or a mixture thereof, preferably from 0.01% to 10%, more preferably from 0.1% to 5% and most preferably from 0.2% to 2% by weight, when such an agent is present in the hard surface cleaning composition. 
     Suitable polyalkoxylene glycols which can be used herein have the following formula H—O—(CH 2 —CHR 2 O) n —H. 
     Suitable monocapped polyalkoxylene glycols which can be used herein have the following formula R 1 —O—(CH 2 —CHR 2 O) n —H. 
     Suitable dicapped polyalkoxylene glycols which can be used herein are according to the formula R 1 —O—(CH 2 —CHR 2 O) n —R 3 . 
     In these formulas of polyalkoxylene glycols, mono and dicapped polyalkoxylene glycols, the substituents R 1  and R 3  each independently are substituted or unsubstituted, saturated or unsaturated, linear or branched hydrocarbon chains having from 1 to 30 carbon atoms, or amino bearing linear or branched, substituted or unsubstituted hydrocarbon chains having from 1 to 30 carbon atoms, R 2  is hydrogen or a linear or branched hydrocarbon chain having from 1 to 30 carbon atoms, and n is an integer greater than 0. 
     Preferably R 1  and R 3  each independently are substituted or unsubstituted, saturated or unsaturated, linear or branched alkyl groups, alkenyl groups or aryl groups having from 1 to 30 carbon atoms, preferably from 1 to 16, more preferably from 1 to 8 and most preferably from 1 to 4, or amino bearing linear or branched, substituted or unsubstituted alkyl groups, alkenyl groups or aryl groups having from 1 to 30 carbon atoms, more preferably from 1 to 16, even more preferably from 1 to 8 and most preferably from 1 to 4. Preferably R 2  is hydrogen, or a linear or branched alkyl group, alkenyl group or aryl group having from 1 to 30 carbon atoms, more preferably from 1 to 16, even more preferably from 1 to 8, and most preferably R 2  is methyl, or hydrogen. Preferably n is an integer from 5 to 1000, more preferably from 10 to 100, even more preferably from 20 to 60 and most preferably from 30 to 50. 
     The preferred polyalkoxylene glycols, mono and dicapped polyalkoxylene glycols which can be used in the present hard surface cleaning compositions have a molecular weight of at least 200, more preferably from 400 to 5000 and most preferably from 800 to 3000. 
     Suitable monocapped polyalkoxylene glycols which can be used herein include 2-aminopropyl polyethylene glycol (MW 2000), methyl polyethylene glycol (MW 1800) and the like. Such monocapped polyalkoxylene glycols may be commercially available from Hoescht under the polyglycol series or Hunstman under the tradename XTJ®. Preferred polyalkoxylene glycols are polyethylene glycols like polyethylene glycol (MW 2000). 
     Optionally the antiresoiling agent is a dicapped polyalkoxylene glycol as defined herein or a mixture thereof. Suitable dicapped polyalkoxylene glycols which can be used herein include O,O′-bis(2-aminopropyl)polyethylene glycol (MW 2000), O,O′-bis(2-aminopropyl)polyethylene glycol (MW 400), O,O′-dimethyl polyethylene glycol (MW 2000), dimethyl polyethylene glycol (MW 2000) or mixtures thereof. Preferred dicapped polyalkoxylene glycol for use herein is dimethyl polyethylene glycol (MW 2000). For instance dimethyl polyethylene glycol may be commercially available from Hoescht as the polyglycol series, e.g. PEG DME-2000®, or from Huntsman under the tradename Jeffamine® and XTJ®. 
     In a preferred embodiment of the present invention wherein the dicapped polyalkoxylene glycol is an amino dicapped polyalkoxylene glycol, it is preferred for cleaning performance reasons to formulate the liquid compositions herein at a pH equal or lower than the pKa of said amino dicapped polyalkoxylene glycol. Indeed, it has been found that the next-time cleaning performance is especially improved at those pHs when the compositions according to the present invention comprise such an amino dicapped polyalkoxylene glycol, as the dicapped polyalkoxylene glycol. 
     The non-amino dicapped polyalkoxylene glycols as defined herein are pH independent, i.e., the pH of the composition has no influence on the next-time cleaning performance delivered by a composition comprising such a non-amino dicapped polyalkoxylene glycol, as the dicapped polyalkoxylene glycol. 
     By “amino dicapped polyalkoxylene glycol”, it is meant herein a dicapped polyalkoxylene glycol according to the formula R 1 —O—(CH 2 —CHR 2 O) n —R 3 , wherein substituents R 1 , R 2 , R 3  and n are as defined herein before, and wherein at least substituent R 1  or R 3  is an amino bearing linear or branched, substituted or unsubstituted hydrocarbon chain of from 1 to 30 carbon atoms. 
     By “non-amino dicapped polyalkoxylene glycol” it is meant herein a dicapped polyalkoxylene glycol according to the formula R 1 —O—(CH 2 —CHR 2 O) n  —R 3 , wherein substituents R 1 , R 2 , R 3  and n are as defined herein before, and wherein none of the substituents R 1  or R 3  is an amino bearing linear or branched, substituted or unsubstituted hydrocarbon chain of from 1 to 30 carbon atoms. 
     Although the polyalkoxylene glycols and monocapped polyalkoxylene glycols contribute to the next-time cleaning performance delivered by the compositions herein, the dicapped polyalkoxylene glycols are preferred herein as the next-time cleaning performance associated thereto is further improved. Indeed, it has surprisingly been found that dicapping a polyalkoxylene glycol imparts outstanding improved antiresoiling properties to such a compound, as compared to the corresponding non-capped polyalkoxylene glycol, or non-capped polyalkoxylene glycol of equal molecular weight. 
     2) PVP Homopolymers or Copolymers Thereof 
     The hard surface cleaning compositions according to the present invention may contain a vinylpyrrolidone homopolymer or copolymer or a mixture thereof. The compositions of the present invention comprise from 0.001% to 20% by weight of the total composition of a vinylpyrrolidone homopolymer or copolymer or a mixture thereof, preferably from 0.01% to 10%, more preferably from 0.1% to 5% and most preferably from 0.2% to 2%, when PVP homopolymers or copolymers are present. Suitable vinylpyrrolidone homopolymers which can be used herein is an homopolymer of N-vinylpyrrolidone having the following repeating monomer:                    
     wherein n (degree of polymerization) is an integer of from 10 to 1,000,000, preferably from 20 to 100,000, and more preferably from 20 to 10,000. 
     Accordingly, suitable vinylpyrrolidone homopolymers (“PVP”) which can be used herein have an average molecular weight of from 1,000 to 100,000,000, preferably from 2,000 to 10,000,000, more preferably from 5,000 to 1,000,000, and most preferably from 50,000 to 500,000. 
     Suitable vinylpyrrolidone homopolymers are commercially available from ISP Corporation, New York, N.Y. and Montreal, Canada under the product names PVP K-15® (viscosity molecular weight of 10,000), PVP K-30® (average molecular weight of 40,000), PVP K-60® (average molecular weight of 160,000), and PVP K-90® (average molecular weight of 360,000). Other suitable vinylpyrrolidone homopolymers which are commercially available from BASF Cooperation include Sokalan HP 165® and Sokalan HP 12®; vinylpyrrolidone homopolymers known to persons skilled in the detergent field (see for example EP-A-262,897 and EP-A-256,696). 
     Suitable copolymers of vinylpyrrolidone which can be used herein include copolymers of N-vinylpyrrolidone and alkylenically unsaturated monomers or mixtures thereof. 
     The alkylenically unsaturated monomers of the copolymers herein include unsaturated dicarboxylic acids such as maleic acid, chloromaleic acid, fumaric acid, itaconic acid, citraconic acid, phenylmaleic acid, aconitic acid, acrylic acid, N-vinylimidazole and vinyl acetate. Any of the anhydrides of the unsaturated acids may be employed, for example acrylate, methacrylate. Aromatic monomers like styrene, sulphonated styrene, alpha-methyl styrene, vinyl toluene, t-butyl styrene and similar well known monomers may be used. 
     The molecular weight of the copolymer of vinylpyrrolidone is not especially critical so long as the copolymer is water-soluble, has some surface activity and is adsorbed to the hard-surface from the liquid composition or solution (i.e. under dilute usage conditions) comprising it in such a manner as to increase the hydrophilicity of the surface. However, the preferred copolymers of N-vinylpyrrolidone and alkylenically unsaturated monomers or mixtures thereof, have a molecular weight of between 1,000 and 1,000,000, preferably between 10,000 and 500,000 and more preferably between 10,000 and 200,000. 
     For example particularly suitable N-vinylimidazole N-vinylpyrrolidone polymers for use herein have an average molecular weight range from 5,000-1,000,000, preferably from 5,000 to 500,000, and more preferably from 10,000 to 200,000. The average molecular weight range was determined by light scattering as described in Barth H. G. and Mays J. W. Chemical Analysis Vol. 113,“Modern Methods of Polymer Characterization”. 
     Such copolymers of N-vinylpyrrolidone and alkylenically unsaturated monomers like PVP/vinyl acetate copolymers are commercially available under the trade name Luviskol® series from BASF. 
     Particular preferred copolymers of vinylpyrrolidone for use in the compositions of the present invention are quaternized or unquaternized vinylpyrrolidone/dialkylaminoalkyl acrylate or methacrylate copolymers. 
     The vinylpyrrolidone/dialkylaminoalkyl acrylate or methacrylate copolymers (quaternised or unquaternised) suitable for use in the compositions of the present invention are according to the following formula:                    
     in which n is between 20 and 99 and preferably between 40 and 90 mol % and m is between 1 and 80 and preferably between 5 and 40 mol %; R 1  represents H or CH 3 ; y denotes 0 or 1; R 2  is —CH 2 —CHOH—CH 2 — or C X H 2X , in which x=2 to 18; R 3  represents a lower alkyl group of from 1 to 4 carbon atoms, preferably methyl or ethyl, or benzyl; R 4  denotes a lower alkyl group of from 1 to 4 carbon atoms, preferably methyl or ethyl; X− is chosen from the group consisting of Cl, Br, I, ½SO 4 , HSO 4  and CH 3 SO 3 . The polymers can be prepared by the process described in French Pat. Nos. 2,077,143 and 2,393,573. 
     The preferred quaternized or unquatemized vinylpyrrolidone/dialkylaminoalkyl acrylate or methacrylate copolymers suitable for use herein have a molecular weight of between 1,000 and 1,000,000, preferably between 10,000 and 500,000 and more preferably between 10,000 and 100,000. 
     Such vinylpyrrolidone/dialkylaminoalkyl acrylate or methacrylate copolymers are commercially available under the name copolymer 845®, Gafquat 734®, or Gafquat 755® from ISP Corporation, New York, N.Y. and Montreal, Canada or from BASF under the tradename Luviquat®. 
     Most preferred herein is quaternized copolymers of vinyl pyrrolidone and dimethyl aminoethymethacrylate (polyquaternium-11) available from BASF. 
     3) Polycarboxvlate 
     The hard surface cleaning composition of the present invention may optionally contain a polycarboxylate polymer. When present the polycarboxylate polymer will be preferably from about 0.001% to about 10% , more preferably from about 0.01% to about 5%, even more preferably about 0.1% to 2.5%, by weight of composition. 
     Polycarboxylate polymers can be those formed by polymerization of monomers, at least some of which contain carboxylic functionality. Common monomers include acrylic acid, maleic acid, ethylene, vinyl pyrrollidone, methacrylic acid, methacryloylethylbetaine, etc. In general, the polymers should have molecular weights of more than 10,000, preferably more than about 20,000, more preferably more than about 300,000, and even more preferably more than about 400,000. It has also been found that higher molecular weight polymers, e.g., those having molecular weights of more than about 3,000,000, are extremely difficult to formulate and are less effective in providing anti-spotting benefits than lower molecular weight polymers. Accordingly, the molecular weight should normally be, especially for polyacrylates, from about 20,000 to about 3,000,000; preferably from about 20,000 to about 2,500,000; more preferably from about 300,000 to about 2,000,000; and even more preferably from about 400,000 to about 1,500,000. 
     An advantage for some polycarboxylate polymers is the detergent builder effectiveness of such polymers. Surprisingly, such polymers do not hurt filming/streaking and like other detergent builders, they provide increased cleaning effectiveness on typical, common “hard-to-remove” soils that contain particulate matter. 
     Some polymers, especially polycarboxylate polymers, thicken the compositions that are aqueous liquids. This can be desirable. However, when the compositions are placed in containers with trigger spray devices, the compositions are desirably not so thick as to require excessive trigger pressure. Typically, the viscosity under shear should be less than about 200 cp, preferably less than about 100 cp, more preferably less than about 50 cp. It can be desirable, however, to have thick compositions to inhibit the flow of the composition off the surface, especially vertical surfaces. 
     4) Sulfonated Polystyrene Polymer 
     Another suitable materials which can be included in to the hard surface cleaning composition of the invention are high molecular weight sulfonated polymers such as sulfonated polystyrene. A typical formula is as follows. 
     
       
         —[CH(C 6 H 4 SO 3 Na)—CH 2 ] n —CH(C 6 H 5 )—CH 2 — 
       
     
     wherein n is a number to give the appropriate molecular weight as disclosed below. 
     Typical molecular weights are from about 10,000 to about 1,000,000, preferably from about 200,000 to about 700,00. 
     Examples of suitable materials for use herein include poly(vinyl pyrrolidone/acrylic acid) sold under the name “Acrylidone”® by ISP and poly(acrylic acid) sold under the name “Accumer”® by Rohm &amp; Haas. Other suitable materials include sulfonated polystyrene polymers sold under the name Versaflex® sold by National Starch and Chemical Company, especially Versaflex 7000. 
     The level of polymer should normally be, when polymer is present in the hard surface cleaning composition, from about 0.01% to about 10%, preferably from about 0.05% to about 0.5%, more preferably from about 0.1% to about 0.3%. 
     f) pH Adjusting Material 
     The hard surface cleaning compositions of the present invention can be formulated at any pH. That is, the hard surface cleaning compositions of the present invention can have a pH from 0 to 14. Typically, the pH range is selected depending upon the end use of the composition, that is what surface the composition is intended to be used on. Alternatively, the pH can be dependent upon the components present in the composition. That is, glass cleaners will typically have an alkaline pH, i.e. pH greater than 7, preferably a pH from about 8 to about 12, more preferably from about 9 to about 12. All purpose cleaners also typically have an alkaline pH, preferably a pH from about 8 to about 12, more preferably from about 9 to about 12. Bath cleaners or acidic cleaners will have an acidic pH, i.e. pH less than 7, preferably a pH from about 0.5 to about 5.5, more preferably from about 1 to about 5. In bleach containing cleaners the pH of the composition depends upon the bleaching agent used, for example, if hydrogenperoxide is the bleach then the composition is acidic, but if the bleach is a chlorine bleach then the pH will be alkaline. Compositions for use on delicate surfaces, such as marble and lacqured wood, will have a mildly acidic to mildly alkaline pH, preferably the pH is from about 6 to 9, more preferably from about 6.5 to 8 and even more preferably from about 7 to about 7.5. The pH adjusting material, if required, can be then selected with the end use and components present in the composition, to give the composition a pH in the desired range. 
     The compositions herein may be optionally formulated in a mildly acidic to mildly alkaline range when the composition is designed to clean delicate surfaces. Accordingly, the compositions for use on delicate surfaces preferably have a pH between 6 and 9, more preferably between 6.5 and 8, and most preferably between 7 and 7.5. At lower pH, the composition would damage marble while, at higher pH, it would damage lacquers. Interestingly, even in neutral pH in which the compositions herein can be formulated, damage to marble would be observed in the absence of the saturated citrate. The pH of the compositions herein can be adjusted by any of the means well known to the man skilled in the art, such as addition of NaOH, KOH, MEA,TEA, MDEA, K2CO3, Na2CO3 and the like, or citric acid, sulphuric acid, nitric acid, hydrochloric acid , maleic acid, acetic acid and the like. 
     Particularly preferred compositions herein comprise an effective amount of a carbonate of the formula XHCO 3  or, if the builder used is not a phosphate-type builder, a phosphate of the formula X a H b PO 4 , where a+b=3 and a or b can be 0, X a H b P 2 O 7  where a+b=4 and a or b can be 0, or X a H b P 3 O 10  where a+b=5 and a or b can be 0, and where X is an alkali metal, particularly K + , Na + , or NH 4   + . Indeed, apart from the pH adjusting effect just described, we have found that the presence of those compounds further improves the safety of the compositions herein to delicate surfaces. Without wishing to be bound by theory, it is believed that the compounds react with the calcium on the surface of marble, to form an insoluble calcium carbonate salt at the marble/solution interface, creating a protective layer. Using these compounds in addition to the saturation technology described hereinabove provides a synergetic effect on delicate surface safety. The amount of these compounds needed in the compositions for use on delicate surfaces can be determined by trial and error, but appears to lie in the range of from 0.05% to 0.4% by weight of the total composition, preferably from 0.05% to 0.1%. Caution needs to be exercised however in that we have observed that too high an amount of XHCO 3  may raise be detrimental to surface safety on lacquered wood. 
     The liquid compositions herein may be formulated in the full pH range of 0 to 14, preferably 1 to 13. Some of the compositions herein are formulated in a neutral to highly alkaline pH range from 7 to 13, preferably from 9 to 11 and more preferably from 9.5 to 11, dependent upon their use and the components present in the composition. The pH of the compositions herein can be adjusted by any of the means well-known to those skilled in the art such as acidifying agents like organic or inorganic acids, or alkalinizing agents like NaOH, KOH, K2CO3, Na2CO3 and the like. Preferred organic acids for use herein have a pK of less than 6. Suitable organic acids are selected from the group consisting of citric acid, lactic acid, glycolic acid, succinic acid, glutaric acid and adipic acid and mixtures thereof. A mixture of said acids may be commercially available from BASF under the trade name Sokalan® DCS. 
     The compositions according to the present invention may further comprise an alkanolamine, or mixtures thereof, in amounts ranging from 0.1% to 10% by weight of the composition, preferably from 0.1% to 7%, most preferably from 0.1% to 5%. At such levels, the alkanolamine has a buffering effect for alkaline products in the undiluted product, as well as an unexpected boosting effect on the cleaning performance of the diluted compositions. Suitable alkanolamines for use in the compositions according to the present include monoalkanolamines, dialkanolamines, trialkanolamines, alkylalkanolamines, dialkylalkanolamines and alkoxyalkanolamines. Preferred alkanolamines to be used according to the present invention include monoethanolamine, triethanolamine, aminoethylpropanediol, 2-aminomethyl propanol, and ethoxyethanolamine. Particularly preferred are monoethanolamine, triethanolamine and ethoxyethanolamine. 
     Monoethanolamine and/or beta-alkanolamine, when present in the composition are used at a level of from about 0.05% to about 10%, preferably from about 0.2% to about 5%. 
     Preferred beta-aminoalkanols have a primary hydroxy group. Suitable beta-aminoalkanols have the formula:                    
     wherein each R 13  is selected from the group consisting of hydrogen and alkyl groups containing from one to four carbon atoms and the total of carbon atoms in the compound is from three to six, preferably four. The amine group is preferably not attached to a primary carbon atom. More preferably the amine group is attached to a tertiary carbon atom to minimize the reactivity of the amine group. Specific preferred beta-aminoalkanols are 2-amino, 1-butanol; 2-amino,2-methylpropanol; and mixtures thereof. The most preferred beta-aminoalkanol is 2-amino,2-methylpropanol since it has the lowest molecular weight of any beta-aminoalkanol which has the amine group attached to a tertiary carbon atom. The beta-aminoalkanols preferably have boiling points below about 175° C. Preferably, the boiling point is within about 5° C. of 165° C. 
     Such beta-aminoalkanols are excellent materials for hard surface cleaning in general and, in the present application, have certain desirable characteristics. 
     Beta-aminoalkanols, and especially the preferred 2-amino-2-methylpropanol, are surprisingly volatile from cleaned surfaces considering their relatively high molecular weights. 
     The compositions can optionally contain, either alone or in addition to the preferred alkanolamines, more conventional alkaline buffers such as ammonia; other C 2-4  alkanolamines; alkali metal hydroxides; silicates; borates; carbonates; and/or bicarbonates. Thus, the buffers that are present usually comprise the preferred monoethanolamine and/or beta-aminoalkanol and additional conventional alkaline material. 
     g) Hydrotropes 
     Hydrotropes are highly preferred optional ingredients. In addition to providing the normal benefits associated with hydrotropes, e.g., phase stability and/or viscosity reduction, hydrotropes can also provide improved suds characteristics. Specifically, when the zwitterionic and/or amphoteric co-surfactants contain a carboxy group as the anionic group, the hydrotrope can improve both the quantity of suds generated, especially when the product is dispensed from a sprayer or foamer, and, at the same time, reduce the amount of time required for the foam to “break”, i.e., the time until the foam has disappeared. Both of these characteristics are valued by consumers, but they are usually considered to be mutually incompatible. The hydrotropes that provide the optimum suds improvements are anionic, especially the benzene and/or alkyl benzene sulfonates. The usual examples of such hydrotropes are the benzene, toluene, xylene, and cumene sulfonates. Typically, these hydrotopes are available as their salts, most commonly the sodium salts. Preferably, the hydrotrope is present in at least about molar equivalency to the zwitterionic and/or amphoteric co-surfactants, when these are present. Preferable levels of hydrotropes, when present, are from about 0.1% to about 5%, more preferably from about 1% to about 3% by weight of composition. 
     Bleach 
     The compositions herein may also comprise a bleaching component. Any bleach known to those skilled in the art may be suitable to be used herein including any peroxygen bleach as well as a chlorine releasing component. 
     Suitable peroxygen bleaches for use herein include hydrogen peroxide or sources thereof. As used herein a source of hydrogen peroxide refers to any compound which produces active oxygen when said compound is in contact with water. Suitable water-soluble sources of hydrogen peroxide for use herein include percarbonates, preformed percarboxylic acids, persilicates, persulphates, perborates, organic and inorganic peroxides and/or hydroperoxides. 
     Suitable chlorine releasing component for use herein is an alkali metal hypochlorite. Advantageously, the composition of the invention are stable in presence of this bleaching component. Although alkali metal hypochlorites are preferred, other hypochlorite compounds may also be used herein and can be selected from calcium and magnesium hypochlorite. A preferred alkali metal hypochlorite for use herein is sodium hypochlorite. 
     The compositions of the present invention that comprise a peroxygen bleach may further comprise a bleach activator or mixtures thereof. By “bleach activator”, it is meant herein a compound which reacts with peroxygen bleach like hydrogen peroxide to form a peracid. The peracid thus formed constitutes the activated bleach. Suitable bleach activators to be used herein include those belonging to the class of esters, amides, imides, or anhydrides. Examples of suitable compounds of this type are disclosed in British Patent GB 1 586 769 and GB 2 143 231 and a method for their formation into a prilled form is described in European Published Patent Application EP-A-62 523. Suitable examples of such compounds to be used herein are tetracetyl ethylene diamine (TAED), sodium 3,5,5 trimethyl hexanoyloxybenzene sulphonate, diperoxy dodecanoic acid as described for instance in U.S. Pat. No. 4,818,425 and nonylamide of peroxyadipic acid as described for instance in U.S. Pat. No. 4,259,201 and n-nonanoyloxybenzenesulphonate (NOBS). Also suitable are N-acyl caprolactams selected from the group consisting of substituted or unsubstituted benzoyl caprolactam, octanoyl caprolactam, nonanoyl caprolactam, hexanoyl caprolactam, decanoyl caprolactam, undecenoyl caprolactam, formyl caprolactam, acetyl caprolactam, propanoyl caprolactam, butanoyl caprolactam pentanoyl caprolactam or mixtures thereof. A particular family of bleach activators of interest was disclosed in EP 624 154, and particularly preferred in that family is acetyl triethyl citrate (ATC). Acetyl triethyl citrate has the advantage that it is environmental-friendly as it eventually degrades into citric acid and alcohol. Furthermore, acetyl triethyl citrate has a good hydrolytical stability in the product upon storage and it is an efficient bleach activator. Finally, it provides good building capacity to the composition. 
     The source of active oxygen according to the present invention acts as an oxidizing agent, it increases the ability of the compositions to remove colored stains and organic stains in general, to destroy malodorous molecules and to kill germs. Suitable sources of active oxygen are hydrogen peroxide or sources thereof. As used herein a hydrogen peroxide source refers to any compound which produces hydrogen peroxide when said compound is in contact with water. Suitable water-soluble inorganic sources of hydrogen peroxide for use herein include persulfate salts (i.e., dipersulfate and monopersulfate salts), persulfuric acid, percarbonates, metal peroxides, perborates and persilicate salts. 
     In addition, other classes of peroxides can be used as an alternative to hydrogen peroxide and sources thereof or in combination with hydrogen peroxide and sources thereof. Suitable classes include dialkylperoxides, diacylperoxide, performed percarboxylic acids, organic and inorganic peroxides and/or hydroperoxides. Suitable organic peroxides/hydroperoxides include diacyl and dialkyl peroxides/hydroperoxides such as dibenzoyl peroxide, t-butyl hydroperoxide, dilauroyl peroxide, dicumyl peroxide, and mixtures thereof. Suitable preformed peroxyacids for use in the compositions according to the present invention include diperoxydodecandioic acid DPDA, magnesium perphthalic acid, perlauric acid, perbenzoic acid, diperoxyazelaic acid and mixtures thereof. 
     Persulfate salts, or mixtures thereof, are the preferred sources of active oxygen to be used in the compositions according to the present invention. Preferred persulfate salt to be used herein is the monopersulfate triple salt. One example of monopersulfate salt commercially available is potassium monopersulfate commercialized by Peroxide Chemie GMBH under the trade name Curox®, by Degussa under the trade name Caroat and from Du Pont under the trade name Oxone. Other persulfate salts such as dipersulfate salts commercially available from Peroxide Chemie GMBH can be used in the compositions according to the present invention. 
     The compositions according to the present invention may optionally comprise up to 30% by weight of the total composition of said bleach, or mixtures thereof, preferably from 0.1% to 20%, more preferably from 0.1% to 10%, and most preferably from 0.1% to 5%. 
     Chelating Agents 
     The hard surface cleaning compositions herein may also optionally contain one or more transition metal chelating agents. Such chelating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures therein, all as hereinafter defined. Without intending to be bound by theory, it is believed that the benefit of these materials is due in part to their exceptional ability to remove iron and manganese ions from washing solutions by formation of soluble chelates. 
     Amino carboxylates useful as optional chelating agents include ethylenediaminetetracetates, N-hydroxyethylethylenediaminetriacetates, nitrilotriacetates, ethylenediamine tetraproprionates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates, and ethanoldiglycines, alkali metal, ammonium, and substituted ammonium salts therein and mixtures therein. 
     A preferred biodegradable chelator for use herein is ethylenediamine disuccinate (“EDDS”), especially the [S,S] isomer as described in U.S. Pat. No. 4,704,233, Nov. 3, 1987, to Hartman and Perkins. 
     If utilized, these chelating agents will generally comprise from about 0.1% to about 10% by weight of the detergent compositions herein. More preferably, if utilized, the chelating agents will comprise from about 0.01% to about 3.0% by weight of such compositions. 
     Optional Components 
     The hard surface cleaning compositions of the present invention may further comprise one or more optional components known for use in hard surface cleaning compositions provided that the optional components are physically and chemically compatible with the essential component described herein, or do not otherwise unduly impair product stability, aesthetics or performance. Concentrations of such optional components typically range from about 0.001% to about 30% by weight of the hard surface cleaning compositions, when present. 
     Optional components include dyes, diluents, antimicrobial agents, antifungal agents, anti mould agents, antimildue agents, inscet repellent, suds suppressors, enzymes, thickeners, thinners, reheology agents (i.e. agents which change or stabilize the rehology of a composition), thixotropic agents, foam boosters, perfumes, preservatives, antioxidants; and aesthetic components such as fragrances, colorings, and the like. This list of optional components is not meant to be exclusive, and other optional components can be used. 
     Packaging Form of the Compositions 
     The compositions herein may be packaged in a variety of suitable detergent packaging known to those skilled in the art. The liquid compositions are preferably packaged in conventional detergent plastic bottles. 
     In one embodiment the compositions herein may be packaged in manually operated spray dispensing containers, which are usually made of synthetic organic polymeric plastic materials. Accordingly, the present invention also encompasses liquid cleaning compositions of the invention packaged in a spray dispenser, preferably in a trigger spray dispenser or pump spray dispenser. 
     Indeed, said spray-type dispensers allow to uniformly apply to a relatively large area of a surface to be cleaned the liquid cleaning compositions suitable for use according to the present invention. Such spray-type dispensers are particularly suitable to clean vertical surfaces. 
     Suitable spray-type dispensers to be used according to the present invention include manually operated foam trigger-type dispensers sold for example by Specialty Packaging Products, Inc. or Continental Sprayers, Inc. These types of dispensers are disclosed, for instance, in U.S. Pat. No. 4,701,311 to Dunnining et al. and U.S. Pat. Nos. 4,646,973 and 4,538,745 both to Focarracci. Particularly preferred to be used herein are spray-type dispensers such as T 8500® commercially available from Continental Spray International or T 8100® commercially available from Canyon, Northern Ireland. In such a dispenser the liquid composition is divided in fine liquid droplets resulting in a spray that is directed onto the surface to be treated. Indeed, in such a spray-type dispenser the composition contained in the body of said dispenser is directed through the spray-type dispenser head via energy communicated to a pumping mechanism by the user as said user activates said pumping mechanism. More particularly, in said spray-type dispenser head the composition is forced against an obstacle, e.g. a grid or a cone or the like, thereby providing shocks to help atomize the liquid composition, i.e. to help the formation of liquid droplets. 
     The present invention also comprises a detergent composition containing the modified alkylbenzene sulfonate surfactant mixture disclosed herein, in a container in association with instructions to use it with an absorbent structure comprising an effective amount of a superabsorbent material, and, optionally, in a container in a kit comprising the implement, or, at least, a disposable cleaning pad comprising a superabsorbent material. 
     The container is based on providing the convenience of a cleaning pad, preferably removable and/or disposable, that contains a superabsorbent material and which preferably also provides significant cleaning benefits. The preferred cleaning performance benefits are related to the preferred structural characteristics described below, combined with the ability of the pad to remove solubilized soils. The cleaning pad, as described herein requires the use of the detergent composition containing the modified alkylbenzene sulfonate surfactant mixture to provide optimum performance. 
     The cleaning pads will preferably have an absorbent capacity when measured under a confining pressure of 0.09 psi after 20 minutes (1200 seconds) (hereafter refered to as “t 1200  absorbent capacity”) of at least about 10 g deionized water per g of the cleaning pad. The cleaning pads will also preferably, but not necessarily, have a total fluid capacity (of deionized water) of at least about 100 g. Each of the components of the absorbent pad are described in detail. 
     The absorbent layer is the essential component which serves to retain any fluid and soil absorbed by the cleaning pad during use. While the preferred scrubbing layer, described hereinafter, has some affect on the pad&#39;s ability to absorb fluid, the absorbent layer plays the major role in achieving the desired overall absorbency. 
     From the essential fluid absorbency perspective, the absorbent layer will be capable of removing fluid and soil from any “scrubbing layer” so that the scrubbing layer will have capacity to continually remove soil from the surface. 
     The absorbent layer will comprise any material that is capable of absorbing and retaining fluid during use. To achieve desired total fluid capacities, it will be preferred to include in the absorbent layer a material having a relatively high capacity (in terms of grams of fluid per gram of absorbent material). As used herein, the term “superabsorbent material” means any absorbent material having a g/g capacity for water of at least about 15 g/g, when measured under a confining pressure of 0.3 psi. 
     Representative superabsorbent materials include water insoluble, water-swellable superabsorbent gelling polymers (referred to herein as “superabsorbent gelling polymers”) which are well known in the literature. These materials demonstrate very high absorbent capacities for water. The superabsorbent gelling polymers useful in the present invention can have a size, shape and/or morphology varying over a wide range. These polymers can be in the form of particles that do not have a large ratio of greatest dimension to smallest dimension (e.g., granules, flakes, pulverulents, interparticle aggregates, interparticle crosslinked aggregates, and the like) or they can be in the form of fibers, sheets, films, foams, laminates, and the like. The use of superabsorbent gelling polymers in fibrous form provides the benefit of providing enhanced retention of the superabsorbent material, relative to particles, during the cleaning process. While their capacity is generally lower for aqueous-based mixtures, these materials still demonstrate significant absorbent capacity for such mixtures. The patent literature is replete with disclosures of water-swellable materials. See, for example, U.S. Pat. No. 3,699,103 (Harper et al.), issued Jun. 13, 1972; U.S. Pat. No. 3,770,731 (Harmon), issued Jun. 20, 1972; U.S. Reissue Pat. No. 32,649 (Brandt et al.), reissued Apr. 19, 1989; U.S. Pat. No. 4,834,735 (Alemany et al.), issued May 30, 1989. 
     Most preferred polymer materials for use in making the superabsorbent gelling polymers are slightly network crosslinked polymers of partially neutralized polyacrylic acids and starch derivatives thereof. Most preferably, the hydrogel- forming absorbent polymers comprise from about 50 to about 95%, preferably about 75%, neutralized, slightly network crosslinked, polyacrylic acid (i.e. poly (sodium acrylate/acrylic acid)). Network crosslinking renders the polymer substantially water-insoluble and, in part, determines the absorptive capacity and extractable polymer content characteristics of the superabsorbent gelling polymers. Processes for network crosslinking these polymers and typical network crosslinking agents are described in greater detail in U.S. Pat. No. 4,076,663. 
     Other useful superbsorbent materials include hydrophilic polymeric foams, such as those described in commonly assigned copending U.S. patent application Ser. No. 08/563,866 (DesMarais et al.), filed Nov. 29, 1995 and U.S. Pat. No. 5,387,207 (Dyer et al.), issued Feb. 7, 1995. 
     The absorbent layer may also consist of or comprise fibrous material. Fibers useful in the present invention include those that are naturally occurring (modified or unmodified), as well as synthetically made fibers. 
     The fibers useful herein can be hydrophilic, hydrophobic or can be a combination of both hydrophilic and hydrophobic fibers. 
     Suitable wood pulp fibers can be obtained from well-known chemical processes such as the Kraft and sulfite processes. 
     Another type of hydrophilic fiber for use in the present invention is chemically stiffened cellulosic fibers. As used herein, the term “chemically stiffened cellulosic fibers” means cellulosic fibers that have been stiffened by chemical means to increase the stiffness of the fibers under both dry and aqueous conditions. 
     Optional, but Preferred, Scrubbing Layer 
     The scrubbing layer is the portion of the cleaning pad that contacts the soiled surface during cleaning. As such, materials useful as the scrubbing layer must be sufficiently durable that the layer will retain its integrity during the cleaning process. In addition, when the cleaning pad is used in combination with a solution, the scrubbing layer must be capable of absorbing liquids and soils, and relinquishing those liquids and soils to the absorbent layer. This will ensure that the scrubbing layer will continually be able to remove additional material from the surface being cleaned. 
     In order to provide desired integrity, materials particularly suitable for the scrubbing layer include synthetics such as polyolefins (e.g., polyethylene and polypropylene), polyesters, polyamides, synthetic cellulosics (e.g., Rayon®), and blends thereof. Such synthetic materials may be manufactured using known process such as carded, spunbond, meltblown, airlaid, needlepunched and the like. 
     Optional Attachment Layer 
     The cleaning pads of the present invention can optionally have an attachment layer that allows the pad to be connected to an implement&#39;s handle or the support head in preferred implements. The attachment layer will be necessary in those embodiments where the absorbent layer is not suitable for attaching the pad to the support head of the handle. The attachment layer may also function as a means to prevent fluid flow through the top surface (i.e., the handle-contacting surface) of the cleaning pad, and may further provide enhanced integrity of the pad. As with the scrubbing and absorbent layers, the attachment layer may consist of a mono-layer or a multi-layer structure, so long as it meets the above requirements. 
     In a preferred embodiment of the present invention, the attachment layer will comprise a surface which is capable of being mechanically attached to the handle&#39;s support head by use of known hook and loop technology. In such an embodiment, the attachment layer will comprise at least one surface which is mechanically attachable to hooks that are permanently affixed to the bottom surface of the handle&#39;s support head. 
     Detergent Composition 
     Detergent compositions containing the modified alkylbenzene sulfonate surfactant mixture which are to be used with an implement containing a superabsorbent material require sufficient detergent to enable the solution to provide cleaning without overloading the superabsorbent material with solution, but cannot have more than about 0.5% detergent surfactant without the performance suffering. Therefore, the level of detergent surfactant should be from about 0.01% to about 0.5%, preferably from about 0.1% to about 0.45%, more preferably from about 0.2% to about 0.45%; the level of hydrophobic materials, including solvent, should be less than about 0.5%, preferably less than about 0.2%, more preferably less than about 0/1%; and the pH should be more than about 9.3. 
     Preferably the compositions containing the modified alkylbenzene sulfonate surfactant mixture which are to be used in combination with the cleaning implement contain a solvent. Suitable solvents include short chain (e.g., C1-C6) derivatives of oxyethylene glygol and oxypropylene glycol, such as mono- and di-ethylene glycol n-hexyl ether, mono-, di- and tri-propylene glycol n-butyl ether, and the like. The level of hydrophobic solvents, e.g., those having solubilities in water of less than about 3%, more preferably less than about 2%. 
     Preferably the compositions containing the modified alkylbenzene sulfonate surfactant mixture which are to be used in combination with the cleaning implement contain a builder. Suitable builders include those derived from phosphorous sources, such as orthophosphate and pyrophosphate, and non-phosphorous sources, such as nitrilotriacetic acid, S,S-ethylene diamine disuccinic acid, and the like. Suitable chelants include ethylenediaminetetraacetic acid and citric acid, and the like. Suitable suds suppressors include silicone polymers and linear or branched C10-C18 fatty acids or alcohols. Suitable enzymes include lipases, proteases, amylases and other enzymes known to be useful for catalysis of soil degradation. The total level of such ingredients is low, preferably less than about 0.1%, more preferably less than about 0.05%, to avoid causing filming streaking problems. Preferably, the compositions should be essentially free of materials that cause filming streaking problems. Accordingly, it is desirable to use alkaline materials that do not cause filming and/or streaking for the majority of the buffering. Suitable alkaline buffers are carbonate, bicarbonate, citrate, etc. The preferred alkaline buffers are alkanol amines having the formula: 
     
       
         CR 2 (NH 2 )CR 2 OH 
       
     
     wherein each R is selected from the group consisting of hydrogen and alkyl groups containing from one to four carbon atoms and the total of carbon atoms in the compound is from three to six, preferably, 2-amino,2-methylpropanol. 
     The compositions containing the modified alkylbenzene sulfonate surfactant mixture which are to be used in combination with the cleaning implement preferably contain a polymer. The level of polymer should be low, e.g., that is from about 0.0001% to about 0.2%, preferably from about 0.0001% to about 0.1% more preferably from about 0.0005% to about 0.08%, by weight of the composition. This very low level is all that is required to produce a better end result cleaning and higher levels can cause streaking/filming, build up, and/or stickiness. 
     While not wishing to be limited by theory, two physical properties are considered critical for the polymer: 1) Hydrophilic nature and 2) Shear-thinning ability. The polymer hydrophilicity is important to ensure strippability in-between cleanings to avoid build-up. The shear-thinning characteristic is important in aiding to spread solution out evenly during use and combined with hydrophilic characterstic helps provide leveling effect. By leveling effect we mean minimizing solution de-wetting and molecular aggregation which typically occurs during dry down. Molecular aggregation leads to visual streaking/filming which is a signal of poor end result cleaning. 
     Suitable examples of polymers include cellulose materials, e.g., carboxymethylcellulose, hydroxymethylcellulose, etc., and synthetic hydrophilic polymers such as polystyrene sulfonate. More preferred are naturally occurring polymers like gum arabic, pectin, guar gum and xanthan gum. Xanthan gum is pariticularly preferred. Xanthan gum is disclosed in U.S. Pat. No. 4,788,006, Bolich, issued Nov. 29, 1986, at Col. 5, line 55 through Col. 6, line 2, said patent being incorporated herein by reference. Many synthetic polymers can provide this benefit, especially polymers that contain hydrophilic groups, e.g., carboxylate groups. Other polymers that can provide shear-thinning and hydrophilicity include cationic materials that also contain hydrophilic groups and polymers that contain multiple ether linkages. Cationic materials include cationic sugar and/or starch derivatives. 
     Preferred polymers are those having higher molecular weights, although molecular weights down to about 5,000 can provide some results. In general, the polymers should have molecular weights of more than about 10,000, preferably more than about 100,000, more preferably more than about 250,000, and even more preferably more than about 500,000. The molecular weight should normally be, from about 10,000 to about 100,000; preferably from about 100,000 to about 1,000,000; more preferably from about 1,000,000 to about 4,000,000; and even more preferably greater than 4,000,000 million. 
     Examples of suitable materials for use herein include polymers preferably selected from the group consisting of xanthan gums, guar gums, gum arabic, pectin poly(styrene sulfonate), and mixtures thereof of monomers and/or polymers. These polymers can also be used in combination with polymers that do not provide the benefit or provide the benefit to lesser extent to achieve an improved end result cleaning. The most preferred is xanthan gum. 
     Cleaning Implements 
     The detergent compositions containing the modified alkylbenzene sulfonate surfactant mixture can be used with an implement for cleaning a surface, the implement preferably comprising: 
     a. a handle; and 
     b. a removable cleaning pad containing an effective amount of a superabsorbent material, and having a plurality of substantially planar surfaces, wherein each of the substantially planar surfaces contacts the surface being cleaned, more preferably said pad is a removable cleaning pad having a length and a width, the pad comprising 
     i. a scrubbing layer; and 
     ii. an absorbent layer comprising a first layer and a second layer, where the first layer is located between the scrubbing layer and the second layer (i.e., the first layer is below the second layer) and has a smaller width than the second layer. 
     The Handle 
     The handle of the above cleaning implement can be any material that will facilitate gripping of the cleaning implement. The handle of the cleaning implement will preferably comprise any elongated, durable material that will provide practical cleaning. The length of the handle will be dictated by the end-use of the implement. 
     The handle will preferably comprise at one end a support head to which the cleaning pad can be releasably attached. To facilitate ease of use, the support head can be pivotably attached to the handle using known joint assemblies. Any suitable means for attaching the cleaning pad to the support head may be utilized, so long as the cleaning pad remains afixed during the cleaning process. Examples of suitable fastening means include clamps, hooks &amp; loops (e.g., Velcro®), and the like. In a preferred embodiment, the support head will comprise hooks on its lower surface that will mechanically attach to the upper layer (preferably a distinct attachment layer) of the absorbent cleaning pad. 
     A preferred handle, comprising a fluid dispensing means, is depicted in FIG. 1 and is fully described in co-pending U.S. patent application Ser. No. 08/756,774, filed Nov. 15, 1996 by V. S. Ping, et al. (Case 6383), which is incorporated by reference herein. Another preferred handle, which does not contain a fluid dispensing means, is depicted in FIGS. 1 a  and 1 b , and is fully described in co-pending U.S. patent application Ser. No. 08/716,775, filed Sep. 23, 1996 by A. J. Irwin (P&amp;G Case 6262), which is incorporated by reference herein. 
     The Cleaning Pad 
     The cleaning pads described hereinbefore can be used without attachment to a handle, or as part of the above cleaning implement. They may therefore be constructed without the need to be attachable to a handle, i.e., such that they may be used either in combination with the handle or as a stand-alone product. As such, it may be preferred to prepare the pads with an optional attachment layer as described hereinbefore. With the exception of an attachment layer, the pads themselves are as described above. 
     More information on these cleaning implements including other possible embodiments can be found in U.S. Patent Application Ser. No. 09/381,550, filed Mar. 20, 1998 by R. A. Masters, et al. (Case 6555).

     The suds suppressor at an effective level, typically from about 0.0005 to about 0.02, preferably from about 0.001 to about 0.01, more preferably from about 0.002 to about 0.003, provides a technical improvement in spotting and filming, particularly on ceramic surfaces. The reason for this is the grout lines on ceramic create low spots as the mop moves across, generating suds. If too high a level of suds is generated, it can dry down into streaks. Furthermore, consumer research shows that suds seen on floor during mopping is perceived by some consumers as leading to film/streaking. 
     Lowering suds on floor during mopping can provide varying degrees of technical and perceptual benefits for not leaving film/streaks. The degree of benefit depends on the level of suds created and to what degree the level of suds is controlled. particularly during mopping. 
     Known suds suppressors can be used, but it is highly desirable to use a silicone suds suppressor since they are effective at very low levels and therefore can minimize the total water insoluble material needed while having at least an effective amount of suds suppressor present.

     Example 38 
     Linear and Branched Alkylbenzene Mixture With a 2/3-Phenyl Index of About 200 and a 2-Methyl-2-Phenyl Index of About 0.02 
     (Alkylbenzene Mixture According to the Invention) 
     110.25 g of the substantially mono methyl branched olefin mixture of example 2, 36.75 g of a nonbranched olefin mixture (decene:undecene:dodecene:tridecene ratio of 2:9:20:18) and 36 g of a shape selective zeolite catalyst (acidic beta zeolite catalyst; Zeocat™ PB/H) are added to a 2 gallon stainless steel, stirred autoclave. Residual olefin and catalyst in the container are washed into the autoclave with 300 mL of n-hexane and the autoclave is sealed. From outside the autoclave cell, 2000 g of benzene (contained in a isolated vessel and added by way of an isolated pumping system inside the isolated autoclave cell) is added to the autoclave. The autoclave is purged twice with 250 psig N 2 , and then charged to 60 psig N 2 . The mixture is stirred and heated to about 200° C. for about 4-5 hours. The autoclave is cooled to about 20° C. overnight. The valve is opened leading from the autoclave to the benzene condenser and collection tank. The autoclave is heated to about 120° C. with continuous collection of benzene. No more benzene is collected by the time the reactor reaches 120° C. The reactor is then cooled to 40° C. and 750 g of n-hexane is pumped into the autoclave with mixing. The autoclave is then drained to remove the reaction mixture. The reaction mixture is filtered to remove catalyst and the n-hexane is removed under vacuum. The product is distilled under vacuum (1-5 mm of Hg). A modified alkylbenzene mixture with a 2/3-Phenyl index of about 200 and a 2-methyl-2-phenyl index of about 0.02 is collected from 76° C.-130° C. (167 g). 
     Example 39 
     Modified Alkylbenzenesulfonic Acid Mixture According to the Invention (Branched and Nonbranched Alkylbenzenesulfonic Acid Mixture) With a 2/3-Phenyl Index of About 200 and a 2-Methyl-2-Phenyl Index of About 0.02 
     The modified alkylbenzene mixture of example 38 is sulfonated with a molar equivalent of chlorosulfonic acid using methylene chloride as solvent. The methylene chloride is removed to give 210 g of a modified alkylbenzenesulfonic acid mixture with a 2/3-Phenyl index of about 200 and a 2-methyl-2-phenyl index of about 0.02. 
     Example 40 
     Modified Alkylbenzenesulfonate, Sodium Salt Mixture According to the Invention (Branched and Nonbranched Alkylbenzenesulfonate, Sodium Salt Mixture) With a 2/3-Phenyl Index of About 200 and a 2-Methyl-2-Phenyl Index of About 0.02 
     The modified alkylbenzenesulfonic acid of example 39 is neutralized with a molar equivalent of sodium methoxide in methanol and the methanol is evaporated to give 225 g of a modified alkylbenzenesulfonate, sodium salt mixture with a 2/3-Phenyl index of about 200 and a 2-methyl-2-phenyl index of about 0.02.
