Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
213 words
An agglomerated light-duty detergent granule composition comprising (1) from 5% to 60% by weight of an alkylpolysaccharide surfactant having the formula wherein Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms and wherein R is a hydrophobic group selected from the group consisting of alkyl, alkylphenyl groups and mixtures thereof in which said alkyl groups contain from 8 to 18 carbon atoms; said alkyl group being either saturated or unsaturated and containing from 0 to 3 hydroxy groups, R' is ethylene, propylene and/or glyceryl, t is from 0 to 30; and x is a number from 1.5 to 10; (2) from 5% to 60% by weight of an alkyl benzene sulfonate cosurfactant in which the alkyl group contains from 10 to 13 carbon atoms, said alkyl benzene sulfonate neutralized with one or more cationic moieties; (3) from 5% to 60% by weight of an alkylpolyethoxylate sulfate cosurfactant in which the alkyl group contains from 10 to 16 carbon atoms and there are from 1 to 6 ethoxylate groups, said alkylpolyethoxylate sulfates neutralized with one or more cationic moieties; (4) from 5% to 80% by weight of a water-soluble inorganic salt selected from the group consisting of sodium and potassium sulfates, chlorides, carbonates, phosphates and mixtures thereof.
Claim 2
Dependent Claim
213 words
An agglomerated light-duty detergent granule composition comprising (1) from 5% to 60% by weight of an alkylpolysaccharide surfactant having the formula wherein Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms and wherein R is a hydrophobic group selected from the group consisting of alkyl, alkylphenyl groups and mixtures thereof in which said alkyl groups contain from 8 to 18 carbon atoms; said alkyl group being either saturated or unsaturated and containing from 0 to 3 hydroxy groups, R' is ethylene, propylene and/or glyceryl, t is from 0 to 30; and x is a number from 1.5 to 10; (2) from 5% to 60% by weight of an alkyl benzene sulfonate cosurfactant in which the alkyl group contains from 10 to 13 carbon atoms, said alkyl benzene sulfonate neutralized with one or more cationic moieties; (3) from 5% to 60% by weight of an alkylpolyethoxylate sulfate cosurfactant in which the alkyl group contains from 10 to 16 carbon atoms and there are from 1 to 6 ethoxylate groups, said alkylpolyethoxylate sulfates neutralized with one or more cationic moieties; (4) from 5% to 80% by weight of a water-soluble inorganic salt selected from the group consisting of sodium and potassium sulfates, chlorides, carbonates, phosphates and mixtures thereof.
Claim 3
Dependent Claim
32 words

Claim 4
Dependent Claim
28 words
The composition of Claim 2 wherein the phenyl portion of the alkylbenzene sulfonate is attached near the middle of the alkyl chain and the cationic moiety is magnesium.
Claim 5
Dependent Claim

A composition according to Claim 1-3 wherein x is a number of from 1.5 to 4.
Claim 6
Dependent Claim
14 words
The composition of Claims 1-3 wherein x is a number from 1.6 to 2.7.
