Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 243 words
A foaming composition comprising from about 0.01% to about 95% of surfactants comprising (1) an alkylpolysaccharide surfactant having the formula RO(R 1 O) t (Z) x where Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms and wherein R is an alkyl, alkylphenyl, hydroxy alkylphenyl or hydroxyalkyl hydrophobic group or mixtures thereof in which said alkyl groups contain from about 8 to about 18 carbon atoms; R 1 contains from 2 to about 4 carbon atoms; t is from 0 to about 30; and x is a number from about 1.5 to about 10; (2) a mixture of anionic cosurfactants neutralized with one or more cationic moieties consisting essentially of: (a) from about 1% to about 95% of a water soluble alkylbenzene sulfonate in which the alkyl group contains from about 10 to 13 carbon atoms, and (b) from about 5% to about 99% of a cosurfactant selected from the group consisting of an alkyl glyceryl ether sulfonate in which the alkyl group contained from about 8 to about 18 carbon atoms, an alpha-olefin sulfonate in which the olefin group contains from about 10 to about 18 carbon atoms, an alkyl polyethoxylate carboxylate in which the alkyl group contains from about 10 to about 18 carbon atoms, and the polyethoxylate chain contains from about 2 to about 6 ethoxylate groups, and mixtures thereof, the ratio of (1) to (2) being from about 1:10 to about 10:1.
Claim 2
Dependent Claim 243 words
A foaming composition comprising from about 0.01% to about 95% of surfactants comprising (1) an alkylpolysaccharide surfactant having the formula RO(R 1 O) t (Z) x where Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms and wherein R is an alkyl, alkylphenyl, hydroxy alkylphenyl or hydroxyalkyl hydrophobic group or mixtures thereof in which said alkyl groups contain from about 8 to about 18 carbon atoms; R 1 contains from 2 to about 4 carbon atoms; t is from 0 to about 30; and x is a number from about 1.5 to about 10; (2) a mixture of anionic cosurfactants neutralized with one or more cationic moieties consisting essentially of: (a) from about 1% to about 95% of a water soluble alkylbenzene sulfonate in which the alkyl group contains from about 10 to 13 carbon atoms, and (b) from about 5% to about 99% of a cosurfactant selected from the group consisting of an alkyl glyceryl ether sulfonate in which the alkyl group contained from about 8 to about 18 carbon atoms, an alpha-olefin sulfonate in which the olefin group contains from about 10 to about 18 carbon atoms, an alkyl polyethoxylate carboxylate in which the alkyl group contains from about 10 to about 18 carbon atoms, and the polyethoxylate chain contains from about 2 to about 6 ethoxylate groups, and mixtures thereof, the ratio of (1) to (2) being from about 1:10 to about 10:1.
Claim 3
Dependent Claim 38 words
The composition of claim 1 wherein the cosurfactant (2) (b) is an alkyl glyceryl ether sulfonate and the cationic moiety is selected from the group consisting of sodium, potassium, ammonium, monoethanolammonium, diethanolammonium, triethanolammonium, calcium, magnesium and mixtures thereof.
Claim 4
Dependent Claim 15 words
The composition of claim 1 wherein the cosurfactant (2) (b) is an alkyl polyethoxylate carboxylate.
Claim 5
Dependent Claim 15 words
The composition of claim 1 wherein the cosurfactant (2) (b) is an alpha olefin sulfonate.
Claim 6
Dependent Claim 19 words
A composition according to any one of claims 1-4 wherein x is a number of from 1.5 to 4.
Claim 7
Dependent Claim 16 words
The composition any one of claims 1-4 wherein x is a number from 1.6 to 2.7.
Claim 8
Dependent Claim 48 words
A light-duty liquid detergent composition comprising from about 5% of the surfactant mixture of claim 1 and from about 1% to about 5% of a solvent selected from the group consisting of C 1-3 alkanols, C 1-3 alkanolamines, C 2-4 polyols, and mixtures thereof, and the balance water.
