Abstract

A detergent composition comprising:

(a) a surfactant selected from the group consisting of an anionic surfactant, a nonionic surfactant, an amphoteric surfactant, a zwitterionic surfactant, and mixtures thereof;

(b) a cationic polymer; and

(c) a zeolite.

Claims

1. A detergent composition comprising:

(a) a surfactant selected from the group consisting of an anionic surfactant, a nonionic surfactant, an amphoteric surfactant, a zwitterionic surfactant, and mixtures thereof;

(b) a cationic polymer;

(c) a zeolite, and

(d) a phyllosilicate.

2. The composition of claim 1 wherein the surfactant is present in the composition in an amount of from about 1 to 50% by weight, based on the weight of the composition.

3. The composition of claim 1 wherein the cationic polymer is present in the composition in an amount of from about 0.1 to 10% by weight, based on the weight of the composition.

4. The composition of claim 1 wherein the zeolite is present in the composition in an amount of from about 10 to 60% by weight, based on the weight of the composition.

5. The composition of claim 1 wherein the phyllosilicate is present in the composition in an amount of from about 1 to 10% by weight, based on the weight of the composition.

6. The composition of claim 1 wherein the surfactant is present in the composition in an amount of from about 5 to 25% by weight, based on the weight of the composition.

7. The composition of claim 1 wherein the cationic polymer is present in the composition in an amount of from about 1 to 8% by weight, based on the weight of the composition.

8. The composition of claim 1 wherein the zeolite is present in the composition in an amount of from about 15 to 25% by weight, based on the weight of the composition.

9. The composition of claim 1 wherein the phyllosilicate is present in the composition in an amount of from about 3 to 8% by weight, based on the weight of the composition.

10. A process for cleaning and softening textiles comprising contacting the textiles with a cleaning solution containing water and a detergent composition, the detergent composition comprising:

(a) a surfactant selected from the group consisting of an anionic surfactant, a nonionic surfactant, an amphoteric surfactant, a zwitterionic surfactant, and mixtures thereof;

(b) a cationic polymer;

(c) a zeolite, and

(d) a phyllosilicate.

11. The process of claim 10 wherein the surfactant is present in the composition in an amount of from about 1 to 50% by weight, based on the weight of the composition.

12. The process of claim 10 wherein the cationic polymer is present in the composition in an amount of from about 0.1 to 10% by weight, based on the weight of the composition.

13. The process of claim 10 wherein the zeolite is present in the composition in an amount of from about 10 to 60% by weight, based on the weight of the composition.

14. The process of claim 10 wherein the phyllosilicate is present in the composition in an amount of from about 1 to 10% by weight, based on the weight of the composition.

15. The process of claim 10 wherein the surfactant is present in the composition in an amount of from about 5 to 25% by weight, based on the weight of the composition.

16. The process of claim 10 wherein the cationic polymer is present in the composition in an amount of from about 1 to 8% by weight, based on the weight of the composition.

17. The process of claim 10 wherein the zeolite is present in the composition in an amount of from about 20 to 40% by weight, based on the weight of the composition.

18. The process of claim 10 wherein the phyllosilicate is present in the composition in an amount of from about 3 to 8% by weight, based on the weight of the composition.
