Liquid hard-surface cleaning compositions

Abstract: Liquid hard-surface cleaning compositions are disclosed which comprise particular dicapped polyalkoxylene glycols. These compositions provide excellent next-time cleaning performance on hard-surfaces soiled by various soils, especially greasy type soils and/or burnt/sticky food residues typically found in a kitchen.

Description: Technical Field The present invention relates to liquid compositions for cleaning hard-surfaces. Background Liquid compositions for cleaning hard-surfaces have been disclosed in the art. Much of the focus for such compositions has been on providing outstanding cleaning on a variety of soils and surfaces. However, such compositions are not fully satisfactory from a consumer viewpoint especially regarding the soil release properties imparted to the hard-surfaces treated therewith. Indeed, consumers are looking for liquid cleaning compositions that would render a hard surface first treated therewith less prone to soil adherence and thus facilitate next-time (subsequent) cleaning operation. Thus, the object of the present invention is to formulate a liquid cleaning composition for removal of various soils from hard-surfaces that will facilitate the next-time cleaning operation. It has now been found that the next-time cleaning performance is improved when a hard-surface has first been treated with a liquid composition comprising a particular antiresoiling ingredient, namely a dicapped polyalkoxylene glycol of the formula R 1 -O-(CH 2 -CHR 2 O) n -R 3 , wherein 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 wherein n is an integer greater than 0. Indeed, it has surprisingly been found that the use of such a dicapped polyalkoxylene glycol, in a liquid composition, provides improved next-time cleaning performance on a hard-surface first treated therewith at low total level of antiresoiling ingredients. Thus, in its broadest aspect, the present invention encompasses the use of a dicapped polyalkoxylene glycol as defined herein, in a liquid composition, to inhibit adherence of soils on a hard-surface after the surface has been first treated with the composition, thereby facilitating the removal of the soils from the surface on next-time cleaning. The present invention also encompasses liquid cleaning compositions with particular dicapped polyalkoxylene glycols as defined herein after. An advantage of the present invention is that the next-time cleaning performance is obtained according to the present invention on various types of stains/soils including typical greasy stains like kitchen grease, and burnt/sticky food residues like burnt milk stains, typically found in a kitchen. Furthermore, another advantage of the present invention is that the next-time cleaning benefit is obtained by using a biodegradable and cost efficient antiresoiling ingredient. Another advantage of the liquid compositions of the present invention is that not only next-time cleaning performance is improved but that also good first time cleaning performance is delivered, as well as good surface appearance after cleaning. Yet another advantage is that the liquid compositions according to the present invention may be used to clean hard-surfaces made of a variety of materials like glazed and non-glazed ceramic tiles, vinyl, no-wax vinyl, linoleum, melamine, glass, plastics, plastified wood, metallic surfaces, both in neat and diluted conditions, e.g., up to a dilution level of 1:200 (composition:water).

The present invention further encompasses a process of cleaning hard-surfaces wherein a liquid composition as defined herein above, is contacted with said surfaces. Detailed Description of the invention In its broadest embodiment, the present invention encompasses the use of a dicapped polyalkoxylene glycol as defined herein, in a liquid composition, to inhibit adherence of soils on a hard-surface after said surface has been first treated with said composition, thereby facilitating the removal of soils from said surface on next-time cleaning. By "treated", it is meant herein that the hard-surface has been contacted with said liquid composition either in its neat or diluted form, optionally rinsed, and left to dry at ambiant temperature, or dried by any conventional means, e.g. a towel. An essential ingredient of the present invention is a dicapped polyalkoxylene glycol or mixture thereof as defined herein after. Typically, such a dicapped polyalkoxylene glycol or mixture thereof is used in a liquid composition at a level of from 0.001% to 20% by weight of the total composition, preferably from 0.01 % to 5%, more preferably from 0.1% to 4% and most preferably from 0.2% to 3%. Suitable dicapped polyalkoxylene glycols to be used herein are according to the formula R 1 -O-(CH 2 -CHR 2 O) n -R 3 , wherein 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 wherein n is an integer greater than 0. Typically 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. Typically R 2 is hydrogen, or a linear or branched alkyl group, alkenyl group or aryl group having from 1 to 30 carbon atoms, preferably from 1 to 16, more preferably from 1 to 8, and most preferably is methyl, or hydrogen. Preferably n is an integer above 20, more preferably above 30 up to 70, even more preferably from 32 to 60 and most preferably from 35 to 50. The preferred dicapped polyalkoxylene glycols to be used according to the present invention have a molecular weight of at least 200, preferably from 400 to 5000, more preferably from 800 to 3000 and most preferably from 1500 to 2500. Particularly suitable dicapped polyalkoxylene glycols to 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 name Jeffamine® and XTJ®. In the 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 comprising it 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 used 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. The present invention is based on the finding that the use of such a dicapped polyalkoxylene glycol, in a liquid hard-surface cleaning composition, provides improved next-time cleaning performance when a hard-surface has been first treated with said composition. Indeed, it has surprisingly been found that dicapping a polyalkoxylene glycol imparts improved antisoiling properties to such a compound, as compared to the corresponding non-capped polyalkoxylene glycol, or non-capped polyalkoxylene glycol of equal molecular weight. Although not wishing to be bound by theory, it is speculated that the dicapped polyalkoxylene glycols as defined herein have in common the property of adsorbing to a hard-surface being first treated therewith, in such a manner that a hygroscopic layer is left behind. The resulting hygroscopic layer can attract and retain ambient atmospheric water vapor to more effectively reduce adhesion of soils once treated and thus facilitate removal of said soils subsequently deposited thereon, i.e. less work (e.g. less scrubbing and/or wiping and/or less chemical action) is required to remove the soils in the next-time cleaning operation, as compared to a similar soiled hard-surface which has been first treated with the same compositions without said dicapped polyalkoxylene glycol. Furthermore, it has surprisingly been found that this next-time cleaning benefit can be obtained at low total level of antiresoiling ingredients. Thus, in a preferred embodiment the compositions herein comprise from 0.2% to 2% by weight of the total composition of the dicapped polyalkoxylene glycol or a mixture thereof, preferably from 0.5% to 2%, and more preferably from 0.5% to 1%. An advantage of the compositions of the present invention is that good first time cleaning performance is also obtained, as well as a good surface appearance after cleaning. By "cleaning performance", it is meant herein cleaning on various types of soils including greasy soils ,like kitchen grease and/or burnt/sticky food residues typically found in a kitchen (e.g., burnt milk). The next-time cleaning benefit is particularly noticeable on greasy soils. The first time dilute cleaning performance may be evaluated by the following test method: Tiles of enamel, vinyl or ceramic are prepared by applying to them a representative grease/particulate artificial soil, followed by aging. The test compositions and the reference composition are diluted (e.g., composition:water 1:50 or 1:100), applied to a sponge, and used to clean the tiles with a Sheen scrub tester. The number of strokes required to clean to 100% clean is recorded. A minimum of 6 replicates can be taken with each result being generated in duplicate against the reference on each soiled tile. The next-time dilute cleaning performance may be evaluated by the following test method: Following the procedure detailed for first time cleaning the tiles used for this previous test are taken and resoiled directly without first being further washed or rinsed. The cleaning procedure is then repeated using the Sheen scrub tester, taking care that the test compositions are used to clean the same part of the tile as was previously cleaned by them. The number of strokes required to clean to 100% clean is recorded. A minimum of 6 replicates can be taken with each result being generated in duplicate against the reference on each soiled tile. This resoiling and cleaning procedure can be repeated up to 5 times. The test method for evaluating neat cleaning performance is identical to above except that the test compositions and reference are used undiluted and that after cleaning a rinsing cycle is performed with clean water. This rinsing cycle may be repeated up to 5 times prior to the resoiling step for next time cleaning evaluation. The liquid compositions used according to the present invention preferably are aqueous compositions comprising different optional ingredients as defined herein after. The liquid compositions: The compositions according to the present invention particularly suitable for the cleaning of a hard-surface, are liquid compositions. The liquid compositions of the present invention are preferably, but not necessarily formulated as aqueous compositions. Aqueous compositions typically comprise from 50% to 99% by weight of the total composition of water, preferably from 60% to 95%, and more preferably from 80% to 95%. The liquid compositions herein may be formulated in the full pH range of 0 to 14, preferably 1 to 13. Typically, 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. 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 alkalinising 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. As an essential ingredient the liquid compositions herein comprise a dicapped polyalkoxylene glycol or mixtures thereof. Suitable dicapped polyalkoxylene glycols to be used in the compositions of the present invention have the formula : R 1 -O-(CH 2 -CHR 2 O) n -R 3 wherein 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 wherein n is an integer greater than 0, with the proviso that when both the substituents R 1 and R 3 independently are substituted or unsubstituted, saturated or unsaturated, linear or branched hydrocarbon chains having from 1 to 30 carbon atoms and R2 is hydrogen or a linear or branched hydrocarbon chain having from 1 to 30 carbon atoms, then n is greater than 20. Preferred dicapped polyalkoxylene glycols for use herein are as described herein before. The present invention is based on the finding that the liquid compositions of the present invention comprising a dicapped polyalkoxylene glycol as defined herein provide improved next-time cleaning performance when treating a hard-surface therewith, as compared to the next-time cleaning performance delivered with the same compositions, but without said antiresoiling ingredient or with another antiresoiling polymer like a poly-(trimethyl aminoethyl) methacrylate. The compositions of the present invention also includes a vinylpyrrolidone homopolymer or copolymer or a mixture thereof. The compositions of the present invention comprise up 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%. Preferred vinylpyrrolidone homopolymers to be used herein is an homopolymer of N-vinylpyrrolidone having the following repeating monomer wherein n (degree of polymerisation) 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, preferred vinylpyrrolidone homopolymers ("PVP") for use 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, NY 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). Preferred copolymers of vinylpyrrolidone for use herein include copolymers of N-vinylpyrrolidone and alkylenically unsaturated monomers or mixtures thereof. Alkylenically unsaturated monomers which may be used to prepare the copolymers 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 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 (quatemised or unquatemised) suitable to be used 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 0or 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 m ethyl or ethyl, or 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, 1/2SO 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 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, NY and Montreal, Canada or from BASF under the tradename Luviquat®. Most preferred herein is quatemized copolymers of vinyl pryrrotidone and dimethyl aminoethymethacrylate (polyquaternium-11) available from BASF. These vinylpyrrolidone homopolymers and/orcopolymers contribute to the benefit of the compositions of the present invention, i.e. they help improving the next-time cleaning performance, but also the first time cleaning performance. Thus, the composition of the present invention further comprises a vinylpyrrolidone homopolymer and/or copolymer on top of said dicapped polyalkoxylene glycol. More particularly, it has surprisingly been found that there is a synergistic effect on next-time cleaning performance associated with the use of a dicapped polyalkoxylene glycol together with a vinylpyrrolidone homopolymer and/or copolymer. Optional ingredients: The liquid compositions according to the present invention may comprise a variety of optional ingredients depending on the technical benefit aimed for and the surface treated. Suitable optional ingredients for use herein include surfactants, builders, chelants, polymers, solvents, buffers, bactericides, hydrotropes, colorants, stabilisers, radical scavengers, bleaches, bleach activators, sud controlling agents like fatty acids, enzymes, soil suspenders, dye transfer agents, brighteners, anti dusting agents, dispersants, dye transfer inhibitors, pigments, dyes and/or perfumes. The liquid compositions of the present invention preferably comprise a surfactant, or mixtures thereof. Said surfactant may be present in the compositions according to the present invention in amounts of from 0.1% to 50% by weight of the total composition, preferably of from 0.1% to 20% and more preferably of from 1% to 10%. Surfactants are desired herein as they further contribute to the cleaning performance and/or gloss benefit of the compositions of the present invention. Surfactants to be used herein include nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants, and mixtures thereof. Particularly preferred surfactants are the nonionic surfactants. Suitable nonionic 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 detergents 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 detergents 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 ethylene 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 surfactant are the alkylpolysaccharides disclosed in U.S. Patent 4,565,647, Llenado, issued January 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, and less desirably, 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 predominantly the 2- position. Although not preferred, 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.

Suitable perfumes to be used herein include materials which provide an olfactory aesthetic benefit and/or cover any "chemical" odor that the product may have. The main function of a small fraction of the highly volatile, low boiling (having low boiling points), perfume components in these perfumes is to improve the fragrance odor of the product itself, rather than impacting on the subsequent odor of the surface being cleaned. However, some of the less volatile, high boiling perfume ingredients provide a fresh and clean impression to the surfaces, and it is desirable that these ingredients be deposited and present on the dry surface. Perfume ingredients can be readily solubilized in the compositions, for instance by the nonionic detergent surfactants.The perfume ingredients and compositions suitable to be used herein are the conventional ones known in the art. Selection of any perfume component, or amount of perfume, is based solely on aesthetic considerations. Suitable perfume compounds and compositions can be found in the art including U.S. Pat. Nos. : 4,145,184, Brain and Cummins, issued March 20, 1979; 4,209,417, Whyte, issued June 24, 1980; 4,515,705, Moeddel, issued May 7, 1985; and 4,152,272, Young, issued May 1, 1979, all of said patents being incorporated herein by reference. In general, the degree of substantivity of a perfume is roughly proportional to the percentages of substantive perfume material used. Relatively substantive perfumes contain at least about 1%, preferably at least about 10%, substantive perfume materials. Substantive perfume materials are those odorous compounds that deposit on surfaces via the cleaning process and are detectable by people with normal olfactory acuity. Such materials typically have vapor pressures lower than that of the average perfume material. Also, they typically have molecular weights of about 200 and above, and are detectable at levels below those of the average perfume material.Perfume ingredients useful herein, along with their odor character, and their physical and chemical properties, such as boiling point and molecular weight, are given in "Perfume and Flavor Chemicals (Aroma Chemicals)," Steffen Arctander, published by the author, 1969, incorporated herein by reference.

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 hard-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 US-4,701,311 to Dunnining et al. and US-4,646,973 and US-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 atomise the liquid composition, i.e. to help the formation of liquid droplets. The process of cleaning a hard-surface: The present invention also encompasses a process of cleaning a hard-surface wherein a liquid composition comprising a vinylpyrrolidone homopolymer or copolymer or a mixture thereof at a level up to 20% by weight of the total composition and a dicapped polyalkoxylene glycol according to the formula: R 1 -O-(CH 2 -CHR 2 O) n -R 3 wherein 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 wherein n is an integer greater than 0, with the proviso that when both the substituents R 1 and R 3 independently are substituted or unsubstituted, saturated or unsaturated, linear or branched hydrocarbon chains having from 1 to 30 carbon atoms and R2 is hydrogen or a linear or branched hydrocarbon chain having from 1 to 30 carbon atoms, then n is greater than 20, is contacted with said surface.
