Title: Dishwashing detergent compositions containing organic polyamines

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is the National Stage of International Application No. PCT/US00/10391, filed on Apr. 18, 2000, which claims the benefit of U.S. Provisional Application No. 60/129,951, filed on Apr. 19, 1999. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to hand dishwashing detergent compositions containing polyamines. More particularly, the invention is directed to detergent compositions for hand dishwashing which have improved grease removal performance and benefits in sudsing. The detergents of this invention also have improved low temperature stability properties and superior dissolution, as well as improved tough food stain removal. 
     BACKGROUND OF THE INVENTION 
     Typical commercial hand dishwashing compositions incorporate divalent ions (Mg, Ca) to ensure adequate grease performance in soft water. However, the presence of divalent ions in formulas containing anionic, nonionic, or additional surfactants (e.g., amine oxide, alkyl ethoxylate, alkanoyl glucose amide, alkyl betaines) leads to slower rates of product mixing with water (and hence poor flash foam), poor rinsing, and poor low temperature stability properties. Moreover, preparation of stable dishwashing detergents containing Ca/Mg is very difficult due to the precipitation issues associated with Ca and Mg as pH increases. Additionally, hand dishwashing formulations which contain magnesium as well as amine oxide and an anionic surfactant have the added stability problem that at low temperatures, typically about 5° C. or less, the product solidifies. This eliminates a potentially useful surfactant system from any possible combinations with magnesium. 
     However, the alternatives to a conventional Ca/Mg system while solving the stability problem associated with a conventional Ca/Mg system do not typically provide comparable soft water cleaning. 
     Consequently, there remains the need for a detergent composition suitable for hand dishwashing, which is stable at low temperatures, and additionally can provide grease removal and tough food cleaning benefits, in hard water and at pH&#39;s, typically pH 9 or lower, where a conventional Ca/Mg system would be unstable and not provide grease removal and tough food cleaning benefits, while comparable cleaning to a conventional Ca/Mg system in soft water. 
     SUMMARY OF THE INVENTION 
     It has now been determined that the use of polyamines leads to improved cleaning of tough food stains and removal of grease/oil when compared to the use of diamine alone in soft water in conventional detergent compositions. It has also been surprisingly found that the combination of these polyamines with low molecular weight diamines, detailed hereafter, leads to improved cleaning of tough food stains and removal of grease/oil when compared to the use of diamine alone in soft water in conventional detergent compositions. Unexpectedly, these organic diamines also improve suds stability in the presence of soils, esp. soils containing fatty acids and proteins. This combination provides cleaning in soft water which is comparable or better than a conventional Ca/Mg system. 
     In accordance with a first aspect of the present invention a hand dishwashing detergent composition is provided for, the composition comprises: 
     (a) surfactant; 
     (b) polyamine, wherein said polyamine contains at least 3 protonatable nitrogen atoms and at least one pKa above the wash pH (as measured as a 0.2% aqueous solution) and at least two pKa&#39;s greater than about 6 and below wash pH (as measured as a 0.2% aqueous solution); 
     wherein the pH (as measured as 10% aqueous solution) is from about 6.0 to about 12. 
     In accordance with a second aspect of the present invention a hand dishwashing detergent composition is provided for, the composition comprises: 
     (a) surfactant; 
     (b) a low molecular weight organic diamine having a pK1 and a pK2, wherein the pK1 and the pK2 of said diamine are both in the range of from about 8.0 to about 11.5; 
     (c) a polyamine, wherein said polyamine contains at least 3 protonatable nitrogen atoms and has a molecular weight of from about 140 daltons to about 3000 daltons; 
     wherein the pH (as measured as 10% aqueous solution) is from about 6.0 to about 11; and the mole ratio of said protonatable nitrogen to moles of anionic surfactant is from about 10:1 to about 1:15, preferably about 6:1 to about 1:10, more preferably about 3:1 to about 1:5. 
     Accordingly, it is an aspect of the present invention to provide novel cleaning compositions as well as methods of using these novel compositions. These, and other, aspects, features and advantages will be clear from the following detailed description and the appended claims. In the description of the invention various embodiments and/or individual features are disclosed. As will be apparent for the skilled practitioner all combinations of such embodiments and features are possible and can result in preferred executions of the invention. All parts, percentages and ratios used herein are expressed as percent weight unless otherwise specified. All documents cited are, in relevant part, incorporated herein by reference. 
     DETAILED DESCRIPTION OF THE INVENTION 
     Definitions—The present detergent compositions comprise an “effective amount” or a “grease removal-improving amount” of individual components defined herein. By an “effective amount” of the diamines herein and adjunct ingredients herein is meant an amount which is sufficient to improve, either directionally or significantly at the 90% confidence level, the performance of the cleaning composition against at least some of the target soils and stains. Thus, in a composition whose targets include certain grease stains, the formulator will use sufficient diamine to at least directionally improve cleaning performance against such stains. Importantly, in a fully-formulated detergent the diamine can be used at levels which provide at least a directional improvement in cleaning performance over a wide variety of soils and stains, as will be seen from the examples presented hereinafter. 
     As noted, the diamines are used herein in detergent compositions in combination with detersive surfactants at levels which are effective for achieving at least a directional improvement in cleaning performance. In the context of a hand dishwashing composition, such “usage levels” can vary depending not only on the type and severity of the soils and stains, but also on the wash water temperature, the volume of wash water and the length of time the dishware is contacted with the wash water. 
     Since the habits and practices of the users of detergent compositions show considerable variation, the composition will preferably contain at least about 0.1%, more preferably at least about 0.2%, even more preferably, at least about 0.25%, even more preferably still, at least about 0.5% by weight of said composition of diamine. The composition will also preferably contain no more than about 15%, more preferably no more than about 10%, even more preferably, no more than about 6%, even more preferably, no more than about 5%, even more preferably still, no more than about 1.5% by weight of said composition of diamine. 
     In one of its several aspects, this invention provides a means for enhancing the removal of greasy/oily soils by combining the specific diamines of this invention with surfactants. Greasy/oily “everyday” soils are a mixture of triglycerides, lipids, complex polysaccharides, fatty acids, inorganic salts and proteinaceous matter. 
     Depending on consumer preferences, the compositions herein may be formulated at viscosities of over about 50, preferably over about 100 centipoise, and more preferably from about 100 to about 400 centipoise. For European formulations, the compositions may be formulated at viscosites of up to about 1000 centipoise. 
     Moreover, the superior rate of dissolution achieved by divalent ion elimination even allows the formulator to make hand dishwashing detergents, especially compact formulations, at even significantly higher viscosities (e.g., 1,000 centipoise or higher) than conventional formulations while maintaining excellent dissolution and cleaning performance. This has significant potential advantages for making compact products with a higher viscosity while maintaining acceptable dissolution. By “compact” or “Ultra” is meant detergent formulations with reduced levels of water compared to conventional liquid detergents. The level of water is less than 50%, preferably less than 30% by weight of the detergent compositions. Said concentrated products provide advantages to the consumer, who has a product which can be used in lower amounts and to the producer who has lower shipping costs. 
     Soft water: is defined herein as water which has a hardness of less than about 15 gpg, preferably less than about 10 gpg, more preferably, less than about 7 gpg, more preferably less than about 2 gpg, even more preferably about 0 gpg (“gpg” is a measure of water hardness that is well known to those skilled in the art, and it stands for “grains per gallon”). 
     Diamines—It is preferred that the diamines used in the present invention are substantially free from impurities. That is, by “substantially free” it is meant that the diamines are over 95% pure, i.e., preferably 97%, more preferably 99%, still more preferably 99.5%, free of impurities. Examples of impurities which may be present in commercially supplied diamines include 2-Methyl-1,3-diaminobutane and alkylhydropyrimidine. Further, it is believed that the diamines should be free of oxidation reactants to avoid diamine degradation and ammonia formation. Additionally, if amine oxide and/or other surfactants are present, the amine oxide or surfactant should be hydrogen peroxide-free, especially when the compositions contain enzymes. The preferred level of hydrogen peroxide in the amine oxide or surfactant paste of amine oxide is 0-40 ppm, more preferably 0-15 ppm. Amine impurities in amine oxide and betaines, if present, should be minimized to the levels referred above for hydrogen peroxide. However, conventional amine oxides, namely those which are not free of hydrogen peroxide, can be used in the compositions of the present invention. 
     Making the compositions free of hydrogen peroxide is important when the compositions contain an enzyme. The peroxide can react with the enzyme and destroy any performance benefits the enzyme adds to the composition. Even small amounts of hydrogen peroxide can cause problems with enzyme containing formulations. However, the diamine can react with any peroxide present and act as an enzyme stabilizer and prevent the hydrogen peroxide from reacting with the enzyme. The only draw back of this stabilization of the enzymes by the diamine is that the nitrogen compounds produced are believed to cause the malodors which can be present in diamine containing compositions. Having the diamine act as an enzyme stabilizer also prevents the diamine from providing the benefits to the composition for which it was originally put in to perform, namely, grease cleaning, sudsing, dissolution and low temperature stability. Therefore, it is preferred to minimize the amount of hydrogen peroxide present as an impurity in the inventive compositions either by using components which are substantially free of hydrogen peroxide and/or by using non-diamine antioxidants even though the diamine can act as an enzyme stabilizer, because of the possible generation of malodorous compounds and the reduction in the amount of diamine available present to perform its primary role. 
     It is further preferred that the compositions of the present invention be “malodor” free. That is, that the odor of the headspace does not generate a negative olfactory response from the consumer. This can be achieved in many ways, including the use of perfumes to mask any undesirable odors, the use of stabilizers, such as antioxidants, chelants etc., and/or the use of diamines which are substantially free of impurities. It is believed, without wanting to being limited by theory, that it is the impurities present in the diamines that are the cause of most of the malodors in the compositions of the present invention. These impurities can form during the preparation and storage of the diamines. They can also form during the preparation and storage of the inventive composition. The use of stabilizers such as antioxidants and chelants inhibit and/or prevent the formation of these impurities in the composition from the time of preparation to ultimate use by the consumer and beyond. Hence, it is most preferred to remove, suppress and/or prevent the formation of these malodors by the addition of perfumes, stabilizers and/or the use of diamines which are substantially free from impurities. 
     One type of preferred organic diamines are those in which pK1 and pK2 are in the range of about 8.0 to about 11.5, preferably in the range of about 8.4 to about 11, even more preferably from about 8.6 to about 10.75. Preferred materials for performance and supply considerations are 1,3-bis(methylamine)-cyclohexane, 1,3 propane diamine (pK1=10.5; pK2=8.8), 1,6 hexane diamine (pK1=11; pK2=10), 1,3 pentane diamine (Dytek EP) (pK1=10.5; pK2=8.9), 2-methyl 1,5 pentane diamine (Dytek A) (pK1=11.2; pK2=10.0). Other preferred materials are the primary/primary diamines with alkylene spacers ranging from C4 to C8. In general, it is believed that primary diamines are preferred over secondary and tertiary diamines. 
     Definition of pK1 and pK2—As used herein, “pKa1” and “pKa2” are quantities of a type collectively known to those skilled in the art as “pKa” pKa is used herein in the same manner as is commonly known to people skilled in the art of chemistry. Values referenced herein can be obtained from literature, such as from “Critical Stability Constants: Volume 2, Amines” by Smith and Martel, Plenum Press, NY and London, 1975. Additional information on pKa&#39;s can be obtained from relevant company literature, such as information supplied by Dupont, a supplier of diamines. 
     As a working definition herein, the pKa of the diamines is specified in an all-aqueous solution at 25° C. and for an ionic strength between 0.1 to 0.5 M. The pKa is an equilibrium constant which can change with temperature and ionic strength; thus, values reported in the literature are sometimes not in agreement depending on the measurement method and conditions. To eliminate ambiguity, the relevant conditions and/or references used for pKa&#39;s of this invention are as defined herein or in “Critical Stability Constants: Volume 2, Amines”. One typical method of measurement is the potentiometric titration of the acid with sodium hydroxide and determination of the pKa by suitable methods as described and referenced in “The Chemist&#39;s Ready Reference Handbook” by Shugar and Dean, McGraw Hill, NY, 1990. 
     It has been determined that substituents and structural modifications that lower pK1 and pK2 to below about 8.0 are undesirable and cause losses in performance. This can include substitutions that lead to ethoxylated diamines, hydroxy ethyl substituted diamines, diamines with oxygen in the beta (and less so gamma) position to the nitrogen in the spacer group (e.g., Jeffamine EDR 148). In addition, materials based on ethylene diamine are unsuitable. 
     Some of the diamines useful herein can be defined by the following structure:                    
     wherein R 2-5  are independently selected from H, methyl, —CH 3 CH 2 , and ethylene oxides; C x  and C y  are independently selected from methylene groups or branched alkyl groups where x+y is from about 3 to about 6; and A is optionally present and is selected from electron donating or withdrawing moieties chosen to adjust the diamine pKa&#39;s to the desired range. If A is present, then x and y must both be 1 or greater. 
     Alternatively the diamines can be those organic diamines with a molecular weight less than or equal to 400 g/mol. It is preferred that these diamines have the formula:                    
     wherein each R 6  is independently selected from the group consisting of hydrogen, C 1 -C 4  linear or branched alkyl, alkyleneoxy having the formula: 
     
       
         —(R 7 O) m R 8   
       
     
     wherein R 7  is C 2 -C 4  linear or branched alkylene, and mixtures thereof; R 8  is hydrogen, C 1 -C 4  alkyl, and mixtures thereof; m is from 1 to about 10; X is a unit selected from: 
     i) C 3 -C 10  linear alkylene, C 3 -C 10  branched alkylene, C 3 -C 10  cyclic alkylene, C 3 -C 10  branched cyclic alkylene, an alkyleneoxyalkylene having the formula: 
     
       
         —(R 7 O) m R 7 — 
       
     
     wherein R 7  and m are the same as defined herein above; 
     ii) C 3 -C 10  linear, C 3 -C 10  branched linear, C 3 -C 10  cyclic, C 3 -C 10  branched cyclic alkylene, C 6 -C 10  arylene, wherein said unit comprises one or more electron donating or electron withdrawing moieties which provide said diamine with a pK a  greater than about 8; and 
     iii) mixtures of (i) and (ii) 
     provided said diamine has a pK a  of at least about 8. 
     Examples of preferred diamines include the following: dimethyl aminopropyl amine, 1,6-hexane diamine, 1,3 propane diamine, 2-methyl 1,5 pentane diamine, 1,3-Pentanediamine (available under the tradename Dytek EP), 1,3-diaminobutane, 1,2-bis(2-aminoethoxy)ethane, (available under the tradename Jeffamine EDR 148), Isophorone diamine, 1,3-bis(methylamine)-cyclohexane, and mixtures thereof. 
     Polyamine 
     The compositions of the present invention include a polyamine. Preferably the polyamine is a polyalkylamines. The term polyamine used herein does not include alkoxylated polyalkylamines, such as ethoxylated and/or propoxylated polyalkylamine. These compounds are unsuitable for use in the compositions of the present invention because such substituient and structural modifications lower pKa below about 7.0 and cause losses in performance. Furthermore, while not wanting to be limited to theory, it is believed that alkoxylated polyalkylamines can interact with any anionic surfactant in a negative fashion as well as unwanted steric effects from the alkoxylated polyalkylamines. 
     Preferred polyamine polymers are the C 2 -C 3  polyalkyleneamines and polyalkyleneimines. Particularly preferred polyalkyleneamines and polyalkyleneimines are the polyethyleneamines (PEAs) and polyethyleneimines (PEIs). Preferred have a molecular weight of from about 140 to about 310, preferably from about 140 to about 200. These PEAs can be obtained by reactions involving ammonia and ethylene dichloride, followed by fractional distillation. The common PEAs obtained are triethylenetetramine (TETA) and tetraethylenepentamine (TEPA). Above the pentamines, i.e., the hexamines, heptamines, octamines and possibly nonamines, the cogenerically derived mixture does not appear to separate by distillation and can include other materials such as cyclic amines and particularly piperazines. There can also be present cyclic amines with side chains in which nitrogen atoms appear. See U.S. Pat. No. 2,792,372 to Dickson, issued May 14, 1957, which describes the preparation of PEAs. 
     Preferred PEIs used herein have an average molecular weight of from about 600 to about 2600. Although linear polymer backbones are possible, branched chains can also occur. The relative proportions of primary, secondary and tertiary amine groups present in the polymer can vary, depending on the manner of preparation. These PEIs can be prepared, for example, by polymerizing ethyleneimine in the presence of a catalyst such as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc. Specific methods for preparing PEIs are disclosed in U.S. Pat. No. 2,182,306 to Ulrich et al., issued Dec. 5, 1939; U.S. Pat. No. 3,033,746 to Mayle et al., issued May 8, 1962; U.S. Pat. No. 2,208,095 to Esselmann et al., issued Jul. 16, 1940; U.S. Pat. No. 2,806,839 to Crowther, issued Sep. 17, 1957; and U.S. Pat. No. 2,553,696 to Wilson, issued May 21, 1951 (all incorporated herein by reference). 
     Generally, the polyamines can be included in an amount of from about 0.001% to about 5% by weight of the composition, with the preferred range being from about 0.005% to about 3% by weight, and a more preferred range of about 0.01% to 2%. 
     An example of suitable polyalkylamine has the general formula:                    
     wherein B is a continuation by branching of the polyethyleneimine backbone and E is hydrogen, lower alkyl (that is C 1  to C 6  alkyl), or mixtures thereof. 
     The units which make up the polyalkyleneimine backbones are derived from primary amine units having the formula: 
     
       
         [H 2 N—CH 2 CH 2 ]— and —NH 2   
       
     
     which terminate the main backbone and any branching chains, secondary amine units having the formula:                    
     and tertiary amine units having the formula:                    
     which are the branching points of the main and secondary backbone chains, B representing a continuation of the chain structure by branching. During the formation of the polyamine backbones cyclization may occur, therefore, an amount of cyclic polyamine can be present in the parent polyalkyleneimine backbone mixture. 
     In one embodiment of the present invention, the indices w, x, and y have the following values: w+x+y is from 3 to 9. The polyamines of the present invention comprise at least 3 protonatable nitrogen atoms. 
     Most preferred polyamines are selected from the group consisting of triethylenetetramine (TETA) tetraethylenepentamine (TEPA), hexaethylhexamine, heptaethylheptamines, octaethyloctamines, nonethylnonamines, and mixtures thereof, more preferably triethylenetetramine (TETA) tetraethylenepentamine (TEPA), and mixtures therof. 
     Surfactant 
     The compositions according to the present invention contain a surfactant, preferably selected from: anionic surfactants, nonionic surfactants; amphoteric surfactants; zwiterionic surfactants and mixtures thereof. 
     A wide range of these surfactants can be used in the compositions used in the methods of the present invention. A typical listing of anionic, nonionic, amphoteric and zwitterionic classes, and species of these surfactants, is given in U.S. Pat. No. 3,664,961 issued to Norris on May 23, 1972 and in “Surface Active Agents and Detergents” (Vol. I and II by Schwartz, Perry and Berch). Amphoteric surfactants are also described in detail in “Amphoteric Surfactants, Second Edition”, E. G. Lomax, Editor (published 1996, by Marcel Dekker, Inc.) 
     The composition will preferably contain at least about 0.01%, more preferably at least about 0.1%, even more preferably still, at least about 0.2%, even more preferably still, at least about 0.5% by weight of said composition of surfactant. The composition will also preferably contain no more than about 90%, more preferably no more than about 70%, even more preferably, no more than about 60%, even more preferably, no more than about 35% by weight of said composition of surfactant. 
     Anionic Surfactants—The anionic surfactants useful in the present invention are preferably selected from the group consisting of, linear alkylbenzene sulfonate, alpha olefin sulfonate, paraffin sulfonates, alkyl ester sulfonates, alkyl sulfates, alkyl alkoxy sulfate, alkyl sulfonates, alkyl alkoxy carboxylate, alkyl alkoxylated sulfates, sarcosinates, taurinates, and mixtures thereof. 
     When present, anionic surfactant will be present typically in an effective amount. More preferably, the composition may contain at least about 0.5%, more preferably at least about 5%, even more preferably still, at least about 10% by weight of said composition of anionic surfactant. The composition will also preferably contain no more than about 90%, more preferably no more than about 50%, even more preferably, no more than about 30% by weight of said composition of anionic surfactant. 
     Alkyl sulfate surfactants are another type of anionic surfactant of importance for use herein. In addition to providing excellent overall cleaning ability when used in combination with polyhydroxy fatty acid amides (see below), including good grease/oil cleaning over a wide range of temperatures, wash concentrations, and wash times, dissolution of alkyl sulfates can be obtained, as well as improved formulability in liquid detergent formulations are water soluble salts or acids of the formula ROSO 3 M wherein R preferably is a C 10 -C 24  hydrocarbyl, preferably an alkyl or hydroxyalkyl having a C 10 -C 20  alkyl component, more preferably a C 12 -C 18  alkyl or hydroxyalkyl, and M is H or a cation, e.g., an alkali (Group IA) metal cation (e.g., sodium, potassium, lithium), substituted or unsubstituted ammonium cations such as methyl-, dimethyl-, and trimethyl ammonium and quaternary ammonium cations, e.g., tetramethyl-ammonium and dimethyl piperdinium and cations derived from alkanolamines such as ethanolamine. diethanolamine, triethanolamine, and mixtures thereof, and the like. Typically, alkyl chains of C 12-16  are preferred for lower wash temperatures (e.g., below about 50° C.) and C 16-18  alkyl chains are preferred for higher wash temperatures (e.g., above about 50° C.). 
     Alkyl alkoxylated sulfate surfactants are another category of useful anionic surfactant. These surfactants are water soluble salts or acids typically of the formula RO(A) m SO 3 M wherein R is an unsubstituted C 10 -C 24  alkyl or hydroxyalkyl group having a C 10 -C 24  alkyl component, preferably a C 12 -C 20  alkyl or hydroxyalkyl, more preferably C 12 -C 18  alkyl or hydroxyalkyl, A is an ethoxy or propoxy unit, m is greater than zero, typically between about 0.5 and about 6, more preferably between about 0.5 and about 3, and M is H or a cation which can be, for example, a metal cation (e.g., sodium, potassium, lithium, etc.), ammonium or substituted-ammonium cation. Alkyl ethoxylated sulfates as well as alkyl propoxylated sulfates are contemplated herein. Specific examples of substituted ammonium cations include methyl-, dimethyl-, trimethyl-ammonium and quaternary ammonium cations, such as tetramethyl-ammonium, dimethyl piperidinium and cations derived from alkanolamines, e.g. monoethanolamine, diethanolamine, and triethanolamine, and mixtures thereof. Exemplary surfactants are C 12 -C 18  alkyl polyethoxylate (1.0) sulfate, C 12 -C 18  alkyl polyethoxylate (2.25) sulfate, C 12 -C 18  alkyl polyethoxylate (3.0) sulfate, and C 12 -C 18  alkyl polyethoxylate (4.0) sulfate wherein M is conveniently selected from sodium and potassium. Surfactants for use herein can be made from natural or synthetic alcohol feedstocks. Chain lengths represent average hydrocarbon distributions, including branching. The anionic surfactant component may comprise alkyl sulfates and alkyl ether sulfates derived from conventional alcohol sources, e.g., natural alcohols, synthetic alcohols such as those sold under the trade name of NEODOL™, ALFOL™, LIAL™, LUTENSOL™ and the like. Alkyl ether sulfates are also known as alkyl polyethoxylate sulfates. 
     Examples of suitable anionic surfactants are given in “Surface Active Agents and Detergents” (Vol. I and II by Schwartz, Perry and Berch). A variety of such surfactants are also generally disclosed in U.S. Pat. No. 3,929,678, issued Dec. 30, 1975 to Laughlin, et al. at Column 23, line 58 through Column 29, line 23. 
     One type of anionic surfactant which can be utilized encompasses alkyl ester sulfonates. These are desirable because they can be made with renewable, non-petroleum resources. Preparation of the alkyl ester sulfonate surfactant component can be effected according to known methods disclosed in the technical literature. For instance, linear esters of C 8 -C 20  carboxylic acids can be sulfonated with gaseous SO 3  according to “The Journal of the American Oil Chemists Society,” 52 (1975), pp. 323-329. Suitable starting materials would include natural fatty substances as derived from tallow, palm, and coconut oils, etc. 
     The preferred alkyl ester sulfonate surfactant, especially for laundry applications, comprises alkyl ester sulfonate surfactants of the structural formula:                    
     wherein R 3  is a C 8 -C 20  hydrocarbyl, preferably an alkyl, or combination thereof, R 4  is a C 1 -C 6  hydrocarbyl, preferably an alkyl, or combination thereof, and M is a soluble salt-forming cation. Suitable salts include metal salts such as sodium, potassium, and lithium salts, and substituted or unsubstituted ammonium salts, such as methyl-, dimethyl-, trimethyl, and quaternary ammonium cations, e.g. tetramethyl-ammonium and dimethyl piperdinium, and cations derived from alkanolamines, e.g. monoethanol-amine, diethanolamine, and triethanolamine. Preferably, R 3  is C 10 -C 16  alkyl, and R 4  is methyl, ethyl or isopropyl. Especially preferred are the methyl ester sulfonates wherein R 3  is C 14 -C 16  alkyl. 
     Other anionic surfactants useful for detersive purposes can also be included in the compositions hereof. These can include salts (including, for example, sodium, potassium, ammonium, and substituted ammonium salts such as mono-, di- and triethanolamine salts) of soap, C 9 -C 20  linear alkylbenzenesulphonates, C 8 -C 22  primary or secondary alkanesulphonates, C 8 -C 24  olefinsulphonates, sulphonated polycarboxylic acids prepared by sulphonation of the pyrolyzed product of alkaline earth metal citrates, e.g., as described in British patent specification No. 1,082,179, alkyl glycerol sulfonates, fatty acyl glycerol sulfonates, fatty oleyl glycerol sulfates, alkyl phenol ethylene oxide ether sulfates, paraffin sulfonates, alkyl phosphates, isothionates such as the acyl isothionates, N-acyl taurates, fatty acid amides of methyl tauride, alkyl succinamates and sulfosuccinates, monoesters of sulfosuccinate (especially saturated and unsaturated C 12 -C 18  monoesters) diesters of sulfosuccinate (especially saturated and unsaturated C 6 -C 14  diesters), N-acyl sarcosinates, sulfates of alkylpolysaccharides such as the sulfates of alkylpolyglucoside (the nonionic nonsulfated compounds being described below), branched primary alkyl sulfates, alkyl polyethoxy carboxylates such as those of the formula RO(CH 2 CH 2 O) k CH 2 COO—M +  wherein R is a C 8 -C 22  alkyl, k is an integer from 0 to 10, and M is a soluble salt-forming cation, and fatty acids esterified with isethionic acid and neutralized with sodium hydroxide. Resin acids and hydrogenated resin acids are also suitable, such as rosin, hydrogenated rosin, and resin acids and hydrogenated resin acids present in or derived from tall oil.

Suitable reducing sugars include glucose, fructose, maltose, lactose, galactose, mannose, and xylose. As raw materials, high dextrose corn syrup, high fructose corn syrup, and high maltose corn syrup can be utilized as well as the individual sugars listed above. These corn syrups may yield a mix of sugar components for Z. It should be understood that it is by no means intended to exclude other suitable raw materials.

     Methods for making polyhydroxy fatty acid amides are known in the art. In general, they can be made by reacting an alkyl amine with a reducing sugar in a reductive amination reaction to form a corresponding N-alkyl polyhydroxyamine, and then reacting the N-alkyl polyhydroxyamine with a fatty aliphatic ester or triglyceride in a condensation/amidation step to form the N-alkyl, N-polyhydroxy fatty acid amide product. Processes for making compositions containing polyhydroxy fatty acid amides are disclosed, for example, in G.B. Patent Specification 809,060, published Feb. 18, 1959, by Thomas Hedley &amp; Co., Ltd., U.S. Pat. No. 2,965,576, issued Dec. 20, 1960 to E. R. Wilson, and U.S. Pat. No. 2,703,798, Anthony M. Schwartz, issued Mar. 8, 1955, and U.S. Pat. No. 1,985,424, issued Dec. 25, 1934 to Piggott, each of which is incorporated herein by reference. 
     Examples of such surfactants include the C 10 -C 18  N-methyl, or N-hydroxypropyl, glucamides. The N-propyl through N-hexyl C 12 -C 16  glucamides can be used for lower sudsing performance.

Specific examples of such amides are monoethanol amine coconut fatty acid amide and diethanolamine dodecyl fatty acid amide. These acyl moieties may be derived from naturally occurring glycerides, e.g., coconut oil, palm oil, soybean oil, and tallow, but can be derived synthetically, e.g., by the oxidation of petroleum or by hydrogenation of carbon monoxide by the Fischer-Tropsch process. The monoethanolamides and diethanolamides of C 12-14  fatty acids are preferred. 
     Amphoteric Surfactants—Amphoteric surfactants may optionally be incorporated into the detergent compositions hereof. These surfactants can be broadly described as aliphatic derivatives of secondary or tertiary amines, or aliphatic derivatives of heterocyclic secondary and tertiary amines in which the aliphatic radical can be straight chain or branched. One of the aliphatic substituents contains at least about 8 carbon atoms, typically from about 8 to about 18 carbon atoms, and at least one contains an anionic water-solubilizing group, e.g., carboxy, sulfonate, sulfate. See U.S. Pat. No. 3,929,678 to Laughlin et al., issued Dec. 30, 1975 at column 19, lines 18-35 for examples of ampholytic surfactants. Preferred amphoteric include C 12 -C 18  betaines and sulfobetaines (“sultaines”), C 10 -C 18  amine oxides, and mixtures thereof.

     These amine oxide surfactants in particular include C 10 -C 18  alkyl dimethyl amine oxides and C 8 -C 12  alkoxy ethyl dihydroxy ethyl amine oxides. 
     When present, amine oxide surfactant will be present typically in an effective amount.

     Examples of suitable amine oxide surfactants are given in “Surface Active Agents and Detergents” (Vol. I and II by Schwartz, Perry and Berch). 
     Suitable betaine surfactants include those of the general formula:

     Zwitterionic Surfactants—Zwitterionic surfactants can also be incorporated into the detergent compositions hereof. These surfactants can be broadly described as derivatives of secondary and tertiary amines, derivatives of heterocyclic secondary and tertiary amines, or derivatives of quaternary ammonium, quaternary phosphonium or tertiary sulfonium compounds. See U.S. Pat. No. 3,929,678 to Laughlin et al., issued Dec. 30, 1975 at column 19, line 38 through column 22, line 48 for examples of zwitterionic surfactants. Ampholytic and zwitterionic surfactants are generally used in combination with one or more anionic and/or nonionic surfactants. 
     In the compositions of the present invention it is possible for the surfactant to be a combination of different surfactants, Such as, different surfactants of the same type, i.e. LAS with PAS, surfactants of different type, an anionic with an nonionic, i.e an alkyl sulfate and an alkyl ethoxylate. One preferred combination is when the surfactant is a mixture of at least one amine oxide and at least one anionic surfactant. Other surfactants may be present along with this combination. It is also preferred that when the surfactant is a mixture of at least one amine oxide and at least one anionic surfactant then the mole ratio of the anionic surfactant:amine oxide:diamine is from about 100:40:1 to about 9:0.5:1, preferably from about 27:8:1 to about 11:3:1. It has been found that detergent compositions containing anionic surfactant, amine oxide and diamine in this specific mole ratio range provide improved low temperature stability, deliver better grease removal and tough food cleaning benefits at pH less than 12.5, and improved hard water cleaning. 
     Magnesium Ions 
     The presence of magnesium (divalent) ions improves the cleaning of greasy soils for various compositions, i.e., compositions containing alkyl ethoxy sulfates and/or polyhydroxy fatty acid amides. This is especially true when the compositions are used in softened water that contains few divalent ions. It is believed, while not wanting to be limited by theory, that, magnesium ions increase the packing of the surfactants at the oil/water interface, thereby reducing interfacial tension and improving grease cleaning. Compositions of the invention herein containing magnesium ions exhibit good grease removal, manifest mildness to the skin, and provide good storage stability. 
     The composition will preferably contain at least about 0.01%, more preferably at least about 0.015%, more preferably at least about 0.02%, even more preferably still, at least about 0.025% by weight of said composition of magnesium ions. The cleaning composition will also preferably contain no more than about 5%, more preferably no more than about 2.5%, more preferably no more than about 1%, even more preferably, no more than about 0.05% by weight of said composition of magnesium ions. In any event the amount of magnesium ions present will always be equimolar or less than the amount of diamine present in the composition. However, the composition may also be free of magnesium ions, as they are not essential to the invention. 
     Preferably, the magnesium ions are added as a hydroxide, chloride, acetate, formate, oxide or nitrate salt to the compositions of the present invention. 
     Formulating such divalent ion-containing compositions in alkaline pH matrices may be difficult due to the incompatibility of the divalent ions, particularly magnesium, with hydroxide ions. When both divalent ions and alkaline pH are combined with the surfactant mixture of this invention, grease cleaning is achieved that is superior to that obtained by either alkaline pH or divalent ions alone. Yet, during storage, the stability of these compositions becomes poor due to the formation of hydroxide precipitates. Therefore, chelating agents discussed hereinafter may also be necessary. 
     It has been surprisingly found that when magnesium ions are used in the present inventive hand dishwashing compositions at equimolar or less than equimolar amount of diamine the soft water cleaning of the composition improves. Furthemore, this combination of magnesium and diamine surprisingly does not suffer from the stability problems when in combination with amine oxide and an anionic surfactant. The compositions of the present invention are stable at 0° C., where as compositions with greater than equimolar amounts of magnesium than diamine (and outside the scope of the present invention) show no such stability, and fail after a few days at 0° C.

     Amylase enzymes also include those described in WO95/26397 and in co-pending application by Novo Nordisk PCT/DK96/00056. Other specific amylase enzymes for use in the detergent compositions of the present invention therefore include: 
     (a) α-amylases characterised by having a specific activity at least 25% higher than the specific activity of Termamyl® at a temperature range of 25° C. to 55° C. and at a pH value in the range of 8 to 10, measured by the Phadebas® α-amylase activity assay. Such Phadebas® α-amylase activity assay is described at pages 9-10, WO95/26397. 
     (b) α-amylases according (a) comprising the amino sequence shown in the SEQ ID listings in the above cited reference or an α-amylase being at least 80% homologous with the amino acid sequence shown in the SEQ ID listing. 
     (c) α-amylases according (a) obtained from an alkalophilic Bacillus species, comprising the following amino sequence in the N-terminal: His-His-Asn-Gly-Thr-Asn-Gly-Thr-Met-Met-Gln-Tyr-Phe-Glu-Trp-Tyr-Leu-Pro-Asn-Asp. 
     A polypeptide is considered to be X% homologous to the parent amylase if a comparison of the respective amino acid sequences, performed via algorithms, such as the one described by Lipman and Pearson in Science 227, 1985, p. 1435, reveals an identity of X%. 
     (d) α-amylases according (a-c) wherein the α-amylase is obtainable from an alkalophilic Bacillus species; and in particular, from any of the strains NCIB 12289, NCIB 12512, NCIB 12513 and DSM 935. 
     In the context of the present invention, the term “obtainable from” is intended not only to indicate an amylase produced by a Bacillus strain but also an amylase encoded by a DNA sequence isolated from such a Bacillus strain and produced in an host organism transformed with said DNA sequence. 
     (e) α-amylase showing positive immunological cross-reactivity with antibodies raised against an α-amylase having an amino acid sequence corresponding respectively to those α-amylases in (a-d). 
     (f) Variants of the following parent α-amylases which (i) have one of the amino acid sequences shown in corresponding respectively to those α-amylases in (a-e), or (ii) displays at least 80% homology with one or more of said amino acid sequences, and/or displays immunological cross-reactivity with an antibody raised against an α-amylase having one of said amino acid sequences, and/or is encoded by a DNA sequence which hybridizes with the same probe as a DNA sequence encoding an α-amylase having one of said amino acid sequence; in which variants: 
     1. at least one amino acid residue of said parent α-amylase has been deleted; and/or 
     2. at least one amino acid residue of said parent α-amylase has been replaced by a different amino acid residue; and/or 
     3. at least one amino acid residue has been inserted relative to said parent α-amylase; 
     said variant having an α-amylase activity and exhibiting at least one of the following properties relative to said parent α-amylase: increased thermostability, increased stability towards oxidation, reduced Ca ion dependency, increased stability and/or α-amylolytic activity at neutral to relatively high pH values, increased α-amylolytic activity at relatively high temperature and increase or decrease of the isoelectric point (pI) so as to better match the pI value for α-amylase variant to the pH of the medium. 
     Said variants are described in the patent application PCT/DK96/00056. 
     Other amylases suitable herein include, for example, α-amylases described in GB 1,296,839 to Novo; RAPIDASE®, International Bio-Synthetics, Inc. and TERMAMYL®. Novo. FUNGAMYL® from Novo is especially useful. Engineering of enzymes for improved stability, e.g., oxidative stability, is known. See, for example J. Biological Chem., Vol. 260, No. 11, June 1985, pp. 6518-6521. Certain preferred embodiments of the present compositions can make use of amylases having improved stability in detergents such as automatic dishwashing types, especially improved oxidative stability as measured against a reference-point of TERMAMYL® in commercial use in 1993. These preferred amylases herein share the characteristic of being “stability-enhanced” amylases, characterized, at a minimum, by a measurable improvement in one or more of: oxidative stability, e.g., to hydrogen peroxide/tetraacetylethylenediamine in buffered solution at pH 9-10; thermal stability, e.g., at common wash temperatures such as about 60° C.; or alkaline stability, e.g., at a pH from about 8 to about 11, measured versus the above-identified reference-point amylase. Stability can be measured using any of the art-disclosed technical tests. See, for example, references disclosed in WO 9402597. Stability-enhanced amylases can be obtained from Novo or from Genencor International. One class of highly preferred amylases herein have the commonality of being derived using site-directed mutagenesis from one or more of the Bacillus amylases, especially the Bacillus α-amylases, regardless of whether one, two or multiple amylase strains are the immediate precursors. Oxidative stability-enhanced amylases vs. the above-identified reference amylase are preferred for use, especially in bleaching, more preferably oxygen bleaching, as distinct from chlorine bleaching, detergent compositions herein. Such preferred amylases include (a) an amylase according to the hereinbefore incorporated WO 9402597, Novo, Feb. 3, 1994, as further illustrated by a mutant in which substitution is made, using alanine or threonine, preferably threonine, of the methionine residue located in position 197 of the  B. licheniformis  alpha-amylase, known as TERMAMYL®, or the homologous position variation of a similar parent amylase, such as  B. amyloliquefaciens, B. subtilis , or  B. stearothermophilus ; (b) stability-enhanced amylases as described by Genencor International in a paper entitled “Oxidatively Resistant alpha-Amylases” presented at the 207th American Chemical Society National Meeting, Mar. 13-17, 1994, by C. Mitchinson. Therein it was noted that bleaches in automatic dishwashing detergents inactivate alpha-amylases but that improved oxidative stability amylases have been made by Genencor from  B. licheniformis  NCIB38061. Methionine (Met) was identified as the most likely residue to be modified. Met was substituted, one at a time, in positions 8, 15, 197, 256, 304, 366 and 438 leading to specific mutants, particularly important being M197L and M197T with the M197T variant being the most stable expressed variant. Stability was measured in CASCADE® and SUNLIGHT®; (c) particularly preferred amylases herein include amylase variants having additional modification in the immediate parent as described in WO 9510603 A and are available from the assignee, Novo, as DURAMYL®. Other particularly preferred oxidative stability enhanced amylase include those described in WO 9418314 to Genencor International and WO 9402597 to Novo. Any other oxidative stability-enhanced amylase can be used, for example as derived by site-directed mutagenesis from known chimeric, hybrid or simple mutant parent forms of available amylases. Other preferred enzyme modifications are accessible. See WO 9509909 A to Novo. 
     Various carbohydrase enzymes which impart antimicrobial activity may also be included in the present invention. Such enzymes include endoglycosidase, Type II endoglycosidase and glucosidase as disclosed in U.S. Pat. Nos. 5,041,236, 5,395,541, 5,238,843 and 5,356,803 the disclosures of which are herein incorporated by reference. Of course, other enzymes having antimicrobial activity may be employed as well including peroxidases, oxidases and various other enzymes.

     Cellulases—the cellulases usable in the present invention include both bacterial or fungal cellulase. Suitable cellulases are disclosed in U.S. Pat. No. 4,435,307, Barbesgoard et al, which discloses fungal cellulase produced from Humicola insolens. Suitable cellulases are also disclosed in GB-A-2.075.028; GB-A-2.095.275 and DE-OS-2.247.832. 
     Examples of such cellulases are cellulases produced by a strain of Humicola insolens ( Humicola grisea  var.  thermoidea ), particularly the Humicola strain DSM 1800. Other suitable cellulases are cellulases originated from Humicola insolens having a molecular weight of about 50 KDa, an isoelectric point of 5.5 and containing 415 amino acids. Especially suitable cellulases are the cellulases having color care benefits. Examples of such cellulases are cellulases described in European patent application No. 91202879.2, filed Nov. 6, 1991 (Novo). 
     Peroxidase enzymes are used in combination with oxygen sources, e.g. percarbonate, perborate, persulfate, hydrogen peroxide, etc. They are used for “solution bleaching”, i.e. to prevent transfer of dyes or pigments removed from substrates during wash operations to other substrates in the wash solution. Peroxidase enzymes are known in the art, and include, for example, horseradish peroxidase, ligninase, and haloperoxidase such as chloro- and bromo-peroxidase. Peroxidase-containing detergent compositions are disclosed, for example, in PCT International Application WO 89/099813 and in European Patent application EP No. 91202882.6, filed on Nov. 6, 1991. 
     Said cellulases and/or peroxidases are normally incorporated in the detergent composition at levels from 0.0001% to 2% of active enzyme by weight of the detergent composition. 
     The composition will preferably contain at least about 0.0001%, more preferably at least about 0.0002%, more preferably at least about 0.0005%, even more preferably still, at least about 0.001% of active enzyme by weight of the composition of cellulases and/or peroxidases enzyme.

     Lipase 
     Suitable lipase enzymes include those produced by microorganisms of the Pseudomonas group, such as  Pseudomonas stutzeri  ATCC 19.154, as disclosed in British Patent 1,372,034. Suitable lipases include those which show a positive immunological cross-reaction with the antibody of the lipase, produced by the microorganism  Pseudomonas fluorescens  LAM 1057. This lipase is available from Amano Pharmaceutical Co. Ltd., Nagoya, Japan, under the trade name Lipase P “Amano,” hereinafter referred to as “Amano-P”. Further suitable lipases are lipases such as M1 Lipase® and Lipomax® (Gist-Brocades). Other suitable commercial lipases include Amano-CES, lipases ex  Chromobacter viscosum , e.g.  Chromobacter viscosum  var.  lipolyticum  NRRLB 3673 from Toyo Jozo Co., Tagata, Japan;  Chromobacter viscosum  lipases from U.S. Biochemical Corp., U.S.A. and Disoynth Co., The Netherlands, and lipases ex  Pseudomonas gladioli . LIPOLASE® enzyme derived from  Humicola lanuginosa  and commercially available from Novo, see also EP 341,947, is a preferred lipase for use herein. Lipase and amylase variants stabilized against peroxidase enzymes are described in WO 9414951 A to Novo. See also WO 9205249 and RD 94359044. 
     Highly preferred lipases are the D96L lipolytic enzyme variant of the native lipase derived from  Humicola lanuginosa  as described in U.S. Ser. No. 08/341,826. (See also patent application WO 92/05249 viz. wherein the native lipase ex  Humicola lanuginosa  aspartic acid (D) residue at position 96 is changed to Leucine (L). According to this nomenclature said substitution of aspartic acid to Leucine in position 96 is shown as: D96L.) Preferably the  Humicola lanuginosa  strain DSM 4106 is used. 
     In spite of the large number of publications on lipase enzymes, only the lipase derived from  Humicola lanuginosa  and produced in  Aspergillus oryzae  as host has so far found widespread application as additive for washing products. It is available from Novo Nordisk under the tradename Lipolase® and Lipolase Ultra®, as noted above. In order to optimize the stain removal performance of Lipolase, Novo Nordisk have made a number of variants. As described in WO 92/05249, the D96L variant of the native  Humicola lanuginosa  lipase improves the lard stain removal efficiency by a factor 4.4 over the wild-type lipase (enzymes compared in an amount ranging from 0.075 to 2.5 mg protein per liter). Research Disclosure No. 35944 published on Mar. 10, 1994, by Novo Nordisk discloses that the lipase variant (D96L) may be added in an amount corresponding to 0.001-100-mg (5-500,000 LU/liter) lipase variant per liter of wash liquor. 
     Also suitable are cutinases [EC 3.1.1.50] which can be considered as a special kind of lipase, namely lipases which do not require interfacial activation. Addition of cutinases to detergent compositions have been described in e.g. WO-A-88/09367 (Genencor). 
     The composition will preferably contain at least about 0.0001%, more preferably at least about 0.0002%, more preferably at least about 0.0005%, even more preferably still, at least about 0.001% of active enzyme by weight of the composition of lipase enzyme. The composition will also preferably contain no more than about 2%, more preferably no more than about 0.5%, more preferably no more than about 0.1%, even more preferably, no more than about 0.05% of active enzyme by weight of the composition of lipase enzyme. 
     Mannanase 
     The compositions of the present invention may also comprise a mannanase enzyme. Preferably, the mannanase is selected from the group consisting of: three mannans-degrading enzymes: EC 3.2.1.25: β-mannosidase, EC 3.2.1.78: Endo-1,4-β-mannosidase, referred therein after as “mannanase” and EC 3.2.1.100: 1,4-β-mannobiosidase and mixtures thereof. (IUPAC Classification-Enzyme nomenclature, 1992 ISBN 0-12-227165-3 Academic Press). 
     More preferably, the treating compositions of the present invention, when a mannanase is present, comprise a β-1,4-Mannosidase (E.C. 3.2.1.78) referred to as Mannanase. The term “mannanase” or “galactomannanase” denotes a mannanase enzyme defined according to the art as officially being named mannan endo-1,4-beta-mannosidase and having the alternative names beta-mannanase and endo-1,4-mannanase and catalysing the reaction: random hydrolysis of 1,4-beta-D-mannosidic linkages in mannans, galactomannans, glucomannans, and galactoglucomannans. 
     In particular, Mannanases (EC 3.2.1.78) constitute a group of polysaccharases which degrade mannans and denote enzymes which are capable of cleaving polyose chains contaning mannose units, i.e. are capable of cleaving glycosidic bonds in mannans, glucomannans, galactomannans and galactogluco-mannans. Mannans are polysaccharides having a backbone composed of β-1,4-linked mannose; glucomannans are polysaccharides having a backbone or more or less regularly alternating β-1,4 linked mannose and glucose; galactomannans and galactoglucomannans are mannans and glucomannans with α-1,6 linked galactose sidebranches. These compounds may be acetylated. 
     The degradation of galactomannans and galactoglucomannans is facilitated by full or partial removal of the galactose sidebranches. Further the degradation of the acetylated mannans, glucomannans, galactomannans and galactogluco-mannans is facilitated by full or partial deacetylation. Acetyl groups can be removed by alkali or by mannan acetylesterases. The oligomers which are released from the mannanases or by a combination of mannanases and α-galactosidase and/or mannan acetyl esterases can be further degraded to release free maltose by β-mannosidase and/or β-glucosidase. 
     Mannanases have been identified in several Bacillus organisms. For example, Talbot et al., Appl. Environ. Microbiol., Vol.56, No. 11, pp. 3505-3510 (1990) describes a beta-mannanase derived from  Bacillus stearothermophilus  in dimer form having molecular weight of 162 kDa and an optimum pH of 5.5-7.5. Mendoza et al., World J. Microbiol. Biotech., Vol. 10, No. 5, pp. 551-555 (1994) describes a beta-mannanase derived from  Bacillus subtilis  having a molecular weight of 38 kDa, an optimum activity at pH 5.0 and 55 C and a pI of 4.8. JP-03047076 discloses a beta-mannanase derived from Bacillus sp., having a molecular weight of 373 kDa measured by gel filtration, an optimum pH of 8-10 and a pI of 5.3-5.4. JP-63056289 describes the production of an alkaline, thermostable beta-mannanase which hydrolyses beta-1,4-D-mannopyranoside bonds of e.g. mannans and produces manno-oligosaccharides. JP-63036774 relates to the Bacillus microorganism FERM P-8856 which produces beta-mannanase and beta-mannosidase at an alkaline pH. JP-08051975 discloses alkaline beta-mannanases from alkalophilic Bacillus sp. AM-001. A purified mannanase from  Bacillus amyloliquefaciens  useful in the bleaching of pulp and paper and a method of preparation thereof is disclosed in WO 97/11164. WO 91/18974 describes a hemicellulase such as a glucanase, xylanase or mannanase active at an extreme pH and temperature. WO 94/25576 discloses an enzyme from  Aspergillus aculeatus , CBS 101.43, exhibiting mannanase activity which may be useful for degradation or modification of plant or algae cell wall material. WO 93/24622 discloses a mannanase isolated from  Trichoderma reseei  useful for bleaching lignocellulosic pulps. An hemicellulase capable of degrading mannan-containing hemicellulose is described in WO91/18974 and a purified mannanase from  Bacillus amyloliquefaciens  is described in WO97/11164.

     Preferably, the specificity of an endoglucanase towards xyloglucan is further defined as a relative activity determined as the release of reducing sugars at optimal conditions obtained by incubation of the enzyme with xyloglucan and the other substrate to be tested, respectively. For instance, the specificity may be defined as the xyloglucan to β-glucan activity (XGU/BGU), xyloglucan to carboxy methyl cellulose activity (XGU/CMCU), or xyloglucan to acid swollen Avicell activity (XGU/AVIU), which is preferably greater than about 50, such as 75, 90 or 100. 
     The term “derived from” as used herein refers not only to an endoglucanase produced by strain CBS 101.43, but also an endoglucanase encoded by a DNA sequence isolated from strain CBS 101.43 and produced in a host organism transformed with said DNA sequence. The term “homologue” as used herein indicates a polypeptide encoded by DNA which hybridizes to the same probe as the DNA coding for an endoglucanase enzyme specific for xyloglucan under certain specified conditions (such as presoaking in 5×SSC and prehybridizing for 1 h at −40° C. in a solution of 5×SSC, 5×Denhardt&#39;s solution, and 50 μg of denatured sonicated calf thymus DNA, followed by hybridization in the same solution supplemented with 50 μCi 32-P-dCTP labelled probe for 18 h at −40° C. and washing three times in 2×SSC, 0.2% SDS at 40° C. for 30 minutes). More specifically, the term is intended to refer to a DNA sequence which is at least 70% homologous to any of the sequences shown above encoding an endoglucanase specific for xyloglucan, including at least 75%, at least 80%, at least 85%, at least 90% or even at least 95% with any of the sequences shown above. The term is intended to include modifications of any of the DNA sequences shown above, such as nucleotide substitutions which do not give rise to another amino acid sequence of the polypeptide encoded by the sequence, but which correspond to the codon usage of the host organism into which a DNA construct comprising any of the DNA sequences is introduced or nucleotide substitutions which do give rise to a different amino acid sequence and therefore, possibly, a different amino acid sequence and therefore, possibly, a different protein structure which might give rise to an endoglucanase mutant with different properties than the native enzyme. Other examples of possible modifications are insertion of one or more nucleotides into the sequence, addition of one or more nucleotides at either end of the sequence, or deletion of one or more nucleotides at either end or within the sequence. 
     Endoglucanase specific for xyloglucan useful in the present invention preferably is one which has a XGU/BGU, XGU/CMU and/or XGU/AVIU ratio (as defined above) of more than 50, such as 75, 90 or 100. 
     Furthermore, the endoglucanase specific for xyloglucan is preferably substantially devoid of activity towards β-glucan and/or exhibits at the most 25% such as at the most 10% or about 5%, activity towards carboxymethyl cellulose and/or Avicell when the activity towards xyloglucan is 100%. In addition, endoglucanase specific for xyloglucan of the invention is preferably substantially devoid of transferase activity, an activity which has been observed for most endoglucanases specific for xyloglucan of plant origin. 
     Endoglucanase specific for xyloglucan may be obtained from the fungal species  A. aculeatus , as described in WO 94/14953. Microbial endoglucanases specific for xyloglucan has also been described in WO 94/14953. Endoglucanases specific for xyloglucan from plants have been described, but these enzymes have transferase activity and therefore must be considered inferior to microbial endoglucanses specific for xyloglucan whenever extensive degradation of xyloglucan is desirable. An additional advantage of a microbial enzyme is that it, in general, may be produced in higher amounts in a microbial host, than enzymes of other origins. 
     The xyloglucanase, when present, is incorporated into the treating compositions of the invention preferably at a level of from 0.0001% to 2%, more preferably from 0.0005% to 0.1%, most preferred from 0.001% to 0.02% pure enzyme by weight of the composition. 
     Enzyme Stabilizing System 
     The preferred compositions herein may additionally comprise from about 0.001% to about 10%, preferably from about 0.005% to about 8%, most preferably from about 0.01% to about 6%, by weight of an enzyme stabilizing system. The enzyme stabilizing system can be any stabilizing system which is compatible with the protease or other enzymes used in the compositions herein. Such stabilizing systems can comprise calcium ion, boric acid, propylene glycol, short chain carboxylic acid, boronic acid, polyhydroxyl compounds and mixtures thereof such as are described in U.S. Pat. No. 4,261,868, Hora et al, issued Apr. 14, 1981; U.S. Pat. No. 4,404,115, Tai, issued Sep. 13, 1983; U.S. Pat. No. 4,318,818, Letton et al; U.S. Pat. No. 4,243,543, Guildert et al issued Jan. 6, 1981; U.S. Pat. No. 4,462,922, Boskamp, issued Jul. 31, 1984; U.S. Pat. No. 4,532,064, Boskamp, issued Jul. 30, 1985; and U.S. Pat. No. 4,537,707, Severson Jr., issued Aug. 27, 1985, all of which are incorporated herein by reference. 
     The composition will preferably contain at least about 0.001%, more preferably at least about 0.005%, even more preferably still, at least about 0.01% by weight of the composition of enzyme stabilizing system. The composition will also preferably contain no more than about 10%, more preferably no more than about 8%, no more than about 6% of active enzyme by weight of the composition of enzyme stabilizing system. 
     One stabilizing approach is the use of water-soluble sources of calcium and/or magnesium ions in the finished compositions which provide such ions to the enzymes. Calcium ions are generally more effective than magnesium ions and are preferred herein if only one type of cation is being used. Typical detergent compositions, especially liquids, will comprise from about 1 to about 30, preferably from about 2 to about 20, more preferably from about 8 to about 12 millimoles of calcium ion per liter of finished detergent composition, though variation is possible depending on factors including the multiplicity, type and levels of enzymes incorporated. Preferably water-soluble calcium or magnesium salts are employed, including for example calcium chloride, calcium hydroxide, calcium formate, calcium malate, calcium maleate, calcium hydroxide and calcium acetate; more generally, calcium sulfate or magnesium salts corresponding to the exemplified calcium salts may be used. Further increased levels of Calcium and/or Magnesium may of course be useful, for example for promoting the grease-cutting action of certain types of surfactant. However, it is especially preferred that the composition contain no added calcium ions, and even more preferred that the composition be free of calcium ions. 
     Another stabilizing approach is by use of borate species. See Severson, U.S. Pat. No. 4,537,706. Borate stabilizers, when used, may be at levels of up to 10% or more of the composition though more typically, levels of up to about 3% by weight of boric acid or other borate compounds such as borax or orthoborate are suitable for liquid detergent use. Substituted boric acids such as phenylboronic acid, butaneboronic acid, p-bromophenylboronic acid or the like can be used in place of boric acid and reduced levels of total boron in detergent compositions may be possible though the use of such substituted boron derivatives. 
     Additionally, from 0% to about 10%, preferably from about 0.01% to about 6% by weight, of chlorine bleach or oxygen bleach scavengers can be added to compositions of the present invention to prevent chlorine bleach species present in many water supplies from attacking and inactivating the enzymes, especially under alkaline conditions. While chlorine levels in water may be small, typically in the range from about 0.5 ppm to about 1.75 ppm, the available chlorine in the total volume of water that comes in contact with the enzyme during dishwashing is usually large; accordingly, enzyme stability in-use can be problematic. 
     Suitable chlorine scavenger anions are salts containing ammonium cations. These can be selected from the group consisting of reducing materials like sulfite, bisulfite, thiosulfite, thiosulfate, iodide, etc., antioxidants like carbonate, ascorbate, etc., organic amines such as ethylenediaminetetracetic acid (EDTA) or alkali metal salt thereof and monoethanolamine (MEA), and mixtures thereof. Other conventional scavenging anions like sulfate, bisulfate, carbonate, bicarbonate, percarbonate, nitrate, chloride, borate, sodium perborate tetrahydrate, sodium perborate monohydrate, percarbonate, phosphate, condensed phosphate, acetate, benzoate, citrate, formate, lactate, malate, tartrate, salicylate, etc. and mixtures thereof can also be used.

     Composition pH 
     Dishwashing compositions of the invention will be subjected to acidic stresses created by food soils when put to use, i.e., diluted and applied to soiled dishes. In one embodiment, the dishwashing composition is diluted to a 10% aqueous solution, which has a pH from about 6.0 to about 12. If a composition with a pH greater than 7 is to be more effective, it may optionally contain a buffering agent capable of providing a generally more alkaline pH in the composition and in dilute solutions, i.e., about 0.1% to 0.4% by weight aqueous solution, of the composition. The pKa value of this buffering agent should be about 0.5 to 1.0 pH units below the desired pH value of the composition (determined as described above). Preferably, the pKa of the buffering agent should be from about 7 to about 10. Under these conditions the buffering agent most effectively controls the pH while using the least amount thereof. 
     The buffering agent may be an active detergent in its own right, or it may be a low molecular weight, organic or inorganic material that is used in this composition solely for maintaining an alkaline pH. Preferred buffering agents for compositions of this invention are nitrogen-containing materials. Some examples are amino acids such as lysine or lower alcohol amines like mono-, di-, and tri-ethanolamine.

The composition will also preferably contain no more than about 15%, more preferably no more than about 10%, even more preferably, no more than about 8% by weight of the composition of buffering agent. 
     Hydrotropes—The aqueous liquid carrier may comprise one or more materials which are hydrotropes. Hydrotropes suitable for use in the compositions herein include the C 1 -C 3  alkyl aryl sulfonates, C 6 -C 12  alkanols, C 1 -C 6  carboxylic sulfates and sulfonates, urea, C 1 -C 6  hydrocarboxylates, C 1 -C 4  carboxylates, C 2 -C 4  organic diacids and mixtures of these hydrotrope materials. The liquid detergent composition of the present invention preferably comprises from about 0.5% to 8%, by weight of the liquid detergent composition of a hydrotrope selected from alkali metal and calcium xylene and toluene sulfonates. 
     Suitable C 1 -C 3  alkyl aryl sulfonates include sodium, potassium, calcium and ammonium xylene sulfonates; sodium, potassium, calcium and ammonium toluene sulfonates; sodium, potassium, calcium and ammonium cumene sulfonates; and sodium, potassium, calcium and ammonium substituted or unsubstituted naphthalene sulfonates and mixtures thereof. 
     Suitable C 1 -C 8  carboxylic sulfate or sulfonate salts are any water soluble salts or organic compounds comprising 1 to 8 carbon atoms (exclusive of substituent groups), which are substituted with sulfate or sulfonate and have at least one carboxylic group. The substituted organic compound may be cyclic, acylic or aromatic, i.e. benzene derivatives. Preferred alkyl compounds have from 1 to 4 carbon atoms substituted with sulfate or sulfonate and have from 1 to 2 carboxylic groups. Examples of this type of hydrotrope include sulfosuccinate salts, sulfophthalic salts, sulfoacetic salts, m-sulfobenzoic acid salts and diester sulfosuccinates, preferably the sodium or potassium salts as disclosed in U.S. Pat. No. 3,915,903. 
     Suitable C 1 -C 4  hydrocarboxylates and C 1 -C 4  carboxylates for use herein include acetates and propionates and citrates. Suitable C 2 -C 4  diacids for use herein include succinic, glutaric and adipic acids. 
     Other compounds which deliver hydrotropic effects suitable for use herein as a hydrotrope include C 6 -C 12  alkanols and urea. 
     Preferred hydrotropes for use herein are sodium, potassium, calcium and ammonium cumene sulfonate; sodium, potassium, calcium and ammonium xylene sulfonate; sodium, potassium, calcium and ammonium toluene sulfonate and mixtures thereof. Most preferred are sodium cumene sulfonate and calcium xylene sulfonate and mixtures thereof. These preferred hydrotrope materials can be present in the composition to the extent of from about 0.5% to 8% by weight. 
     The composition will preferably contain at least about 0.1%, more preferably at least about 0.2%, even more preferably still, at least about 0.5% by weight of the composition of hydrotrope. The composition will also preferably contain no more than about 15%, more preferably no more than about 10%, even more preferably, no more than about 8% by weight of the composition of hydrotrope. 
     Other Ingredients—The detergent compositions will further preferably comprise one or more detersive adjuncts selected from the following: soil release polymers, polymeric dispersants, polysaccharides, abrasives, bactericides, tarnish inhibitors, dyes, antifungal or mildew control agents, insect repellents, hydrotropes, processing aids, suds boosters, brighteners, anti-corrosive aids and stabilizers antioxidants. A wide variety of other ingredients useful in detergent compositions can be included in the compositions herein, including other active ingredients, carriers, antioxidants, processing aids, dyes or pigments, solvents for liquid formulations, solid fillers for bar compositions, etc. If high sudsing is desired, suds boosters such as the C 10 -C 16  alkanolamides can be incorporated into the compositions, typically at 1%-10% levels. The C 10 -C 14  monoethanol and diethanol amides illustrate a typical class of such suds boosters. Use of such suds boosters with high sudsing adjunct surfactants such as the amine oxides, betaines and sultaines noted above is also advantageous. 
     An antioxidant can be optionally added to the detergent compositions of the present invention. They can be any conventional antioxidant used in detergent compositions, such as 2,6-di-tert-butyl-4-methylphenol (BHT), carbamate, ascorbate. thiosulfate, monoethanolamine(MEA), diethanolamine, triethanolamine, etc. It is preferred that the antioxidant, when present, be present in the composition from about 0.001% to about 5% by weight. 
     Various detersive ingredients employed in the present compositions optionally can be further stabilized by absorbing said ingredients onto a porous hydrophobic substrate, then coating said substrate with a hydrophobic coating. Preferably, the detersive ingredient is admixed with a surfactant before being absorbed into the porous substrate. 
     In use, the detersive ingredient is released from the substrate into the aqueous washing liquor, where it performs its intended detersive function. 
     To illustrate this technique in more detail, a porous hydrophobic silica (trademark SIPERNAT® D10. DeGussa) is admixed with a proteolytic enzyme solution containing 3%-5% of C 13-15  ethoxylated alcohol (EO 7) nonionic surfactant. Typically, the enzymelsurfactant solution is 2.5× the weight of silica. The resulting powder is dispersed with stirring in silicone oil (various silicone oil viscosities in the range of 500-12,500 can be used). The resulting silicone oil dispersion is emulsified or otherwise added to the final detergent matrix. By this means, ingredients such as the aforementioned enzymes, bleaches, bleach activators, bleach catalysts, photoactivators, dyes, fluorescers, fabric conditioners and hydrolyzable surfactants can be “protected” for use in detergents, including liquid laundry detergent compositions. 
     Form of the Composition 
     The compositions herein can be in any of the conventional forms for hand dishwashing compositions, such as, paste, liquid, granule, powder, gel, and mixtures thereof. Highly preferred embodiments are in liquid or gel form. The liquid compositions can be either aqueous or nonaqueous. When the composition is a aqueous liquid the composition will preferably further contain an aqueous liquid carrier in which the other essential and optional compositions components are dissolved, dispersed or suspended. 
     When the composition is an aqueous liquid the composition will preferably contain at least about 5%, more preferably at least about 10%, even more preferably still, at least about 30% by weight of the composition of aqueous liquid carrier. The composition will also preferably contain no more than about 95%, more preferably no more than about 60%, even more preferably, no more than about 50% by weight of the composition of aqueous liquid carrier. 
     One essential component of the aqueous liquid carrier is, of course, water. The aqueous liquid carrier, however, may contain other materials which are liquid, or which dissolve in the liquid carrier, at room temperature and which may also serve some other function besides that of a simple filler. Such materials can include, for example. hydrotropes and solvents. Low molecular Weight primary or secondary alcohols exemplified by methanol, ethanol, propanol, and isopropanol are suitable. Monohydric alcohols are preferred for solubilizing surfactant, but polyols such as those containing from 2 to about 6 carbon atoms and from 2 to about 6 hydroxy groups (e.g., 1,3-propanediol, ethylene glycol, glycerine, and 1,2-propanediol) can also be used. 
     An example of the procedure for making granules of the detergent compositions herein is as follows:—Linear aklylbenzenesulfonate, citric acid, sodium silicate, sodium sulfate perfume, diamine and water are added to, heated and mixed via a crutcher. The resulting slurry is spray dried into a granular form. 
     An example of the procedure for making liquid detergent compositions herein is as follows:—To the free water and citrate are added and dissolved. To this solution amine oxide, betaine, ethanol, hydrotrope and nonionic surfactant are added. If free water isn&#39;t available, the citrate are added to the above mix then stirred until dissolved. At this point, an acid is added to neutralize the formulation. It is preferred that the acid be chosen from organic acids such as maleic and citric, however, inorganic mineral acids may be employed as well. In preferred embodiments these acids are added to the formulation followed by diamine addition. AExS is added last.
