Abstract

A detergent composition containing: (a) an anionic surfactant selected from the group consisting of an alkylbenzenesulfonate, an alkyl sulfate, a soap, an alkanesulfonate, an olefinsulfonate, a methyl ester sulfonate, and mixtures thereof; (b) a non-enzymatic protein and/or derivative thereof; (c) a phosphate; (d) a disintegrating agent; an (e) optionally, a co-surfactant selected from the group consisting of a nonionic surfactant, an amphoteric surfactant, and mixtures thereof, and wherein the detergent composition is in a solid form.

Claims (32)

1. A detergent composition comprising:

(a) an anionic surfactant selected from the group consisting of an alkylbenzenesulfonate, an alkyl sulfate, a soap, an alkanesulfonate, an olefinsulfonate, a methyl ester sulfonate, and mixtures thereof;

(b) a non-enzymatic protein derivative thereof which derivative comprises a condensation product of a hydrolyzate with a fatty acid having from 6–22 carbon atoms;

(c) a phosphate;

(d) a disintegrating agent; and

(e) optionally, a co-surfactant selected from the group consisting of a nonionic surfactant, an amphoteric surfactant, and mixtures thereof, and wherein the detergent composition is in a tablet form.

2. The composition of claim 1 wherein the composition has a total surfactant content of from about 1 to 50% by weight, based on the weight of the composition.

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

4. The composition of claim 1 wherein the non-enzymatic protein derivative is present in the composition in an amount of from about 0.1 to 10% by weight, based on the weight of the composition.

5. The composition of claim 1 wherein the non-enzymatic protein derivative is present in the composition in an amount of from about 1 to 8% by weight, based on the weight of the composition.

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

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

8. The composition of claim 1 wherein the disintegrating agent is present in the composition in an amount of from about 0.1 to 25% by weight, based on the weight of the composition.

9. The composition of claim 1 wherein the disintegrating agent is present in the composition in an amount of from about 1 to 20% by weight, based on the weight of the composition.

10. The composition of claim 1 wherein the composition is free of cationic surfactant.

11. A process for making a solid-form detergent composition which imparts a soft feel onto clothes treated therewith comprising:

(a) providing an anionic surfactant selected from the group consisting of an alkylbenzenesulfonate, an alkyl sulfate, a soap, an alkanesulfonate, an olefinsulfonate, a methyl ester sulfonate, and mixtures thereof;

(b) providing a non-enzymatic protein derivative thereof which derivative comprises a condensation product of a hydrolyzate with a fatty acid having from 6–22 carbon atoms;

(c) providing a phosphate;

(d) providing a disintegrating agent;

(e) providing, optionally, a co-surfactant selected from the group consisting of a nonionic surfactant, an amphoteric surfactant, and mixtures thereof;

(f) mixing (a)–(e) to form a detergent mixture; and

(g) forming the detergent mixture into a tablet.

12. The process of claim 11 wherein the composition has a total surfactant content of from about 1 to 50% by weight, based on the weight of the composition.

13. The process of claim 11 wherein the surfactant component is present in the composition in an amount of from about 5 to 25% by weight, based on the weight of the composition.

14. The process of claim 11 wherein the non-enzymatic protein derivative is present in the composition in an amount of from about 0.1 to 10% by weight, based on the weight of the composition.

15. The process of claim 11 wherein the non-enzymatic protein derivative is present in the composition in an amount of from about 1 to 8% by weight, based on the weight of the composition.

16. The process of claim 11 wherein the phosphate is present in the composition in an amount of from about 10 to 60% by weight, based on the weight of the composition.

17. The process of claim 11 wherein the phosphate is present in the composition in an amount of from about 15 to 25% by weight, based on the weight of the composition.

18. The process of claim 11 wherein the disintegrating agent is present in the composition in an amount of from about 0.1 to 25% by weight, based on the weight of the composition.

19. The process of claim 11 wherein the disintegrating agent is present in the composition in an amount of from about 1 to 20% by weight, based on the weight of the composition.

20. The process of claim 11 wherein the composition is free of catlonic surfactant.
