Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 214 words
An agglomerated light-duty detergent granule composition comprising (1) from about 5% to about 60% of 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) from about 5% to about 60% of an alkyl benzene sulfonate cosurfactant in which the alkyl group contains from about 10 to about 13 carbon atoms, said alkyl benzene sulfonate neutralized with one or more cationic moieties; (3) from about 5% to about 60% of an alkylpolyethoxylate sulfate cosurfactant in which the alkyl group contains from about 10 to about 16 carbon atoms and there are from about 1 to about 6 ethoxylate groups, said alkylpolyethoxylate sulfates neutralized with one or more cationic moieties; (4) from about 5% to about 80% water soluble inorganic salt selected from the group consisting of sodium and potassium sulfates, chlorides, carbonates, phosphates, and mixtures thereof.
Claim 2
Dependent Claim 214 words
An agglomerated light-duty detergent granule composition comprising (1) from about 5% to about 60% of 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) from about 5% to about 60% of an alkyl benzene sulfonate cosurfactant in which the alkyl group contains from about 10 to about 13 carbon atoms, said alkyl benzene sulfonate neutralized with one or more cationic moieties; (3) from about 5% to about 60% of an alkylpolyethoxylate sulfate cosurfactant in which the alkyl group contains from about 10 to about 16 carbon atoms and there are from about 1 to about 6 ethoxylate groups, said alkylpolyethoxylate sulfates neutralized with one or more cationic moieties; (4) from about 5% to about 80% 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
The composition of claim 1 wherein the cationic moieties for the cosurfactants (2) and (3) are selected from the group consisting of sodium, potassium, ammonium, monoethanolammonium, diethanolammonium, triethanolammonium, magnesium and mixtures thereof.
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.
