Abstract

Proposed are laundry detergent compositions including

(a) anionic surfactants, nonionic and/or amphoteric surfactants,

(b) cationic polymers,

(c) zeolites and optionally

(d) phyllosilicates.

Claims

1. A laundry detergent composition including

(a) anionic surfactants, nonionic and/or amphoteric surfactants,

(b) cationic polymers,

(c) zeolites and optionally

(d) phyllosilicates.

2. The laundry detergent composition of claim 1, including anionic surfactants selected from the group consisting of alkylbenzenesulfonates, alkyl sulfates, soaps, alkanesulfonates, olefinsulfonates and methyl ester sulfonates.

3. The laundry detergent composition of claims 1 and/or 2, including nonionic surfactants selected from the group consisting of fatty alcohol polyglycol ethers, alkoxylated fatty acid lower alkyl esters and alkyl and/or alkenyl oligoglycosides.

4. The laundry detergent composition of at least one of claims 1 to 3, comprising amphoteric surfactants selected from the group consisting of alkyl betaines, alkylamido betaines and imidazolinium betaines.

5. The laundry detergent composition of at least one of claims 1 to 4, including the surfactants of component (a) in amounts from 1 to 50% by weight, based on the laundry detergent composition.

6. The laundry detergent composition of at least one of claims 1 to 5, including cationic polymers selected from the group consisting of cationic cellulose derivatives, cationic starches, copolymers of diallylammonium salts and acrylamides, amides, quaternized vinylpyrrolidone/vinyl-imidazole polymers, condensation products of polyglycols and amines, quaternized collagen poly-peptides, quaternized wheat polypeptides, polyethyleneimine, cationic silicone polymers, copolymers of adipic acid and dimethylamino-hydroxypropyldiethylenetriamine, copolymers of acrylic acid with dimethyldiallylammonium chloride, polyaminopolyamides, cationic chitin derivatives, condensation products of dihaloalkylene with bisdialkylamines, quaternized ammonium salt polymers and cationic guar gums.

7. The laundry detergent composition of at least one of claims 1 to 6, including guar hydroxypropyl-trimethylammonium chloride as cationic polymer.

8. The laundry detergent composition of at least one of claims 1 to 7, including cationic polymers in amounts from 0.1 to 10% by weight, based on the composition.

9. The laundry detergent composition of at least one of claims 1 to 8, including zeolite A and/or zeolite P.

10. The laundry detergent composition of at least one of claims 1 to 9, including phosphates in amounts from 10 to 60% by weight, based on the composition.
