Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 185 words
A mild foaming detergent composition comprising: (1) from about 10% to about 40% of a mild, water-soluble, foaming anionic detergent surfactant having the generic formula RE x SM wherein R is an alkyl group containing from about 12 to about 15 carbon atoms; E represents an ethylene oxide moiety; x is a number from about 1 to about 12 on the average; S is a sulphate group; and M is selected from the group consisting of alkaline metal, alkaline earth metal, ammonium and substituted ammonium cation; (2) from about 1% to about 10% of a surfactant selected from the group consisting of cetyl dimethyl betaine, cetyl amido propyldimethyl betaine, and mixtures thereof; (3) from about 2% to about 10% of an alkyldimethylamine oxide suds booster wherein the alkyl group contains from about 10 to about 14 carbon atoms, wherein when said composition contains harsh surfactants such as C 10-16 alkyl sulfates and C 6-13 alkylbenzene sulfonates, said harsh surfactants are complexed with the amine oxide compound to make them milder, and wherein the ratio of (1) to (2) is from about 3:1 to about 10:1.
Claim 2
Dependent Claim 185 words
A mild foaming detergent composition comprising: (1) from about 10% to about 40% of a mild, water-soluble, foaming anionic detergent surfactant having the generic formula RE x SM wherein R is an alkyl group containing from about 12 to about 15 carbon atoms; E represents an ethylene oxide moiety; x is a number from about 1 to about 12 on the average; S is a sulphate group; and M is selected from the group consisting of alkaline metal, alkaline earth metal, ammonium and substituted ammonium cation; (2) from about 1% to about 10% of a surfactant selected from the group consisting of cetyl dimethyl betaine, cetyl amido propyldimethyl betaine, and mixtures thereof; (3) from about 2% to about 10% of an alkyldimethylamine oxide suds booster wherein the alkyl group contains from about 10 to about 14 carbon atoms, wherein when said composition contains harsh surfactants such as C 10-16 alkyl sulfates and C 6-13 alkylbenzene sulfonates, said harsh surfactants are complexed with the amine oxide compound to make them milder, and wherein the ratio of (1) to (2) is from about 3:1 to about 10:1.
Claim 3
Dependent Claim 172 words
A mild foaming detergent composition comprising: (1) from about 10% to about 40% of a mild, water-soluble, foaming anionic detergent surfactant having the generic formula RE x SM wherein R is an alkyl group containing from about 12 to about 15 carbon atoms; E represents an ethylene oxide moiety; x is a number from about 1 to about 12 on the average; S is a sulphate group; and M is selected from the group consisting of alkaline metal, alkaline earth metal, ammonium and substituted ammonium cation; (2) from about 1% to about 10% of cetyl amido propyldimethyl betaine; and (3) from about 2% to about 10% of an alkyldimethylamine oxide suds booster wherein the alkyl group contains from about 10 to about 14 carbon atoms, wherein when said composition contains harsh surfactants such as C 10-16 alkyl sulfates and C 6-13 alkylbenzene sulfonates, said harsh surfactants are complexed with the amine oxide compound to make them milder, and wherein the ratio of (1) to (2) is from about 3:1 to about 10:1.
Claim 4
Dependent Claim 172 words
A mild foaming detergent composition comprising: (1) from about 10% to about 40% of a mild, water-soluble, foaming anionic detergent surfactant having the generic formula RE x SM wherein R is an alkyl group containing from about 12 to about 15 carbon atoms; E represents an ethylene oxide moiety; x is a number from about 1 to about 12 on the average; S is a sulphate group; and M is selected from the group consisting of alkaline metal, alkaline earth metal, ammonium and substituted ammonium cation; (2) from about 1% to about 10% of cetyl amido propyldimethyl betaine; and (3) from about 2% to about 10% of an alkyldimethylamine oxide suds booster wherein the alkyl group contains from about 10 to about 14 carbon atoms, wherein when said composition contains harsh surfactants such as C 10-16 alkyl sulfates and C 6-13 alkylbenzene sulfonates, said harsh surfactants are complexed with the amine oxide compound to make them milder, and wherein the ratio of (1) to (2) is from about 3:1 to about 10:1.
