Definitions

• the present invention comprises as an essential detergent ingredient a polymer selected from the N-vinylimidazole N-vinylpyrrolidone copolymers.
• Said N-vinylimidazole N-vinylpyrrolidone have found to enhance the detergency performance of certain detergent ingredients formulated therewith.
• the N-vinylimidazole N-vinylpyrrolidone polymers have an average molecular weight range from 5000-1,000,000 , preferably from 20 000 -200,000.
• the level of the N-vinylimidazole N-vinylpyrrolidone present in the detergent compositions is from 0.01 to 10% , more preferably from 0.05 to 5% , most preferably from 0.1 to 1% by weight of the detergent composition.
• a first class of ingredients are surfactant systems wherein the surfactant is a non-alkylbenzene sulfonate salt containing surfactant system wherein the surfactant can be selected from nonionic and/or anionic and/or cationic and/or ampholytic and/or zwitterionic and/or semi-polar surfactants.
• Preferred non-alkylbenzene sulfonate salt containing surfactant systems to be used according to the present invention comprise as a surfactant one or more of the nonionic and/or anionic surfactants described herein. These surfactants have found to be very useful in that the dye transfer inhibiting performance of the N-vinylimidazole N-vinylpyrrolidone copolymers has been increased in the presence of said surfactants.
• Polyethylene, polypropylene, and polybutylene oxide condensates of alkyl phenols are suitable for use as the nonionic surfactant of the surfactant systems of the present invention, with the polyethylene oxide condensates being preferred.
• These compounds include the condensation products of alkyl phenols having an alkyl group containing from about 6 to about 14 carbon atoms, preferably from about 8 to about 14 carbon atoms, in either a straight-chain or branched-chain configuration with the alkylene oxide.
• the ethylene oxide is present in an amount equal to from about 2 to about 25 moles, more preferably from about 3 to about 15 moles, of ethylene oxide per mole of alkyl phenol.
• R1 is methyl
• R2 is a straight C11 ⁇ 15 alkyl or alkenyl chain such as coconut alkyl or mixtures thereof
• Z is derived from a reducing sugar such as glucose, fructose, maltose, lactose, in a reductive amination reaction.
• Suitable anionic surfactants to be used are alkyl ester sulfonate surfactants including linear esters of C8-C20 carboxylic acids (i.e., fatty acids) which are sulfonated with gaseous SO3 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 oil, etc.
• amine oxide surfactants in particular include C10-C18 alkyl dimethyl amine oxides and C8-C12 alkoxy ethyl dihydroxy ethyl amine oxides.
• proteases are the subtilisins which are obtained from particular strains of B.subtilis and B.licheniforms.
• proteases suitable for removing protein-based stains that are commercially available include those sold under the tradenames Alcalase, Savinase and Esperase by Novo Industries A/S (Denmark) and Maxatase by International Bio-Synthetics, Inc. (The Netherlands) and FN-base by Genencor, Optimase and opticlean by MKC.
• compositions can comprise a silicone/silica mixture in combination with fumed nonporous silica such as Aerosil R .
