Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 277 words
I. A foaming composition comprising (I) an alkylpolysaccharide surfactant having the formula RO(R 1 O) t (Z) x wherein 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 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) an anionic cosurfactant selected from the group consisting of sulfates, sulfonates, carboxylates and mixtures thereof neutralized with one or more cationic moieties, the ratio of (2) to (1) being from about 1:10 to about 10:1; and (3) from about 2% to about 10% of an auxiliary foam booster selected from the group consisting of: (a) amides having the formula wherein R is an alkyl group containing from about 8 to about 18 carbon atoms and each R is the same or different and is selected from the group consisting of hydrogen, C 1-3 alkyl, C 1-3 alkanol, and -(C 2 H 4 O-) 1-4 H groups and mixtures thereof; (b) amine oxides having the formula: wherein R 4 is an alkyl group containing from about 8 to about 18 carbon atoms, each R contains from two or three carbon atoms, b is from 0 to about 30, each R is the same or different and is selected from the group consisting of C 1-3 alkyl, C 1-3 alkanol, and -(C 2 H 4 O) 1-6 H groups and mixtures thereof; and (c) mixtures thereof.
Claim 2
Dependent Claim 51 words
The composition of Claim wherein the cosurfactant is selected from the group consisting of alkylbenzene sulfonates, alpha-olefin sulfonates, alkyl sulfates, alkyl polyethoxylate sulfates, and paraffin sulfonates and mixtures thereof and the cationic moiety is selected from the group consisting of sodium, potassium, ammonium, monoethanolammonium, diethanolammonium, triethanolammonium, calcium, magnesium and mixtures thereof.
Claim 3
Dependent Claim 12 words
The composition of Claim 2 wherein the cosurfactant is an alkylbenzene sulfonate.
Claim 4
Dependent Claim 32 words
The composition of Claim 3 wherein the phenyl portion of the alkylbenzene sulfonate is attached near the middle of the alkyl chain and at least about 10% of the cations are magnesium.
Claim 5
Dependent Claim 12 words
The composition of Claim 2 wherein the cosurfactant is an alpha-olefin sulfonate.
Claim 6
Dependent Claim 12 words
The composition of Claim 2 wherein the cosurfactant is a paraffin sulfonate.
Claim 7
Dependent Claim 108 words
The composition of Claim I wherein the cosurfactant is a mixture of (I) from about 5% to about 50% of an alkyl benzene sulfonate in which the alkyl group contains from about 8 to about 13 carbon atoms or an alpha-olefin sulfonate in which the olefin group contains from about 10 to about 18 carbon atoms, or mixtures thereof; and (2) from about 5% to about 50% of an alkyl polyethoxylate sulfate in which the alkyl group contains from about 10 to about 18 carbon atoms and from about one to about six ethoxylate moieties and from about 10% to about 80% of the cationic moieties are magnesium.
Claim 8
Dependent Claim 16 words
A composition according to Claims 1-7 wherein x is a number of from 1.5 to 4.
Claim 9
Dependent Claim 14 words
The composition of Claims 1-7 wherein x is a number from 1.6 to 2.7.
Claim 10
Dependent Claim 51 words
A light-duty liquid detergent composition comprising from about 5% to about 50% of the surfactant mixture of Claim I and from about 1% to about 50% 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.
Claim 11
Dependent Claim 43 words
The composition of Claim 10 wherein the cosurfactant is selected from the group consisting of alkylbenzene sulfonates, alpha-olefin sulfonates, and paraffin sulfonates and the cationic moieties are selected from the group consisting of sodium, potassium, ammonium, monoethanolammonium, diethanolammonium, triethanolammonium, magnesium and mixtures thereof.
Claim 12
Dependent Claim 15 words
