Abstract

Liquid detergent composition that includes a surfactant system and encapsulates. Methods for making and using such detergents.

First claim

What is claimed is:

1. A liquid detergent composition comprising:
A) from about 8% to about 50%, by weight of the detergent composition, of a surfactant system, wherein the surfactant system comprises:
a) a blend of anionic surfactants comprising anionic sulphate surfactant and an anionic sulphonate surfactant in a weight ratio of from about 1.5:1 to about 5:1;
b) a nonionic surfactant comprising an amine oxide;
c) a cationic surfactant; and
d) from 0% to about 4%, by weight of the composition, of fatty acids and/or salts thereof;
wherein the anionic to nonionic surfactant is present in weight ratio of from about 1:1 to about 3.6:1; and

B) from about 0.1% to about 5%, by weight of the composition, of encapsulates, wherein:
i) the encapsulates comprise a core and a wall at least partially surrounding the core;
ii) the core comprises a benefit agent; and
iii) the wall comprises a coating on an outer surface of the wall.

2. A liquid detergent composition according to claim 1 , wherein the composition comprises from about 10% to about 30% of the surfactant system.

3. A liquid detergent composition according to claim 1 , wherein the anionic sulphate surfactant comprises alkoxylated alkyl sulphate surfactant.

4. A liquid detergent composition according to claim 1 , wherein the anionic sulphonate surfactant comprises alkyl benzene sulphonate surfactant.

5. A liquid detergent composition according to claim 1 , wherein the nonionic surfactant further comprises ethoxylated fatty alcohol.

6. A liquid detergent composition according to claim 1 , wherein the composition comprises from about 0.1% to about 3% of the encapsulates.

7. A liquid detergent composition according to claim 1 , wherein the benefit agent comprises perfume raw materials.

8. A liquid detergent composition according to claim 1 , wherein the coating comprises a cationic efficiency polymer.

9. A liquid detergent composition according to claim 8 , wherein the coating comprises a cationic efficiency polymer selected from polyvinyl amines, polyvinyl formamides, polyallyl amines, copolymers thereof, and mixtures thereof.

10. A liquid detergent composition according to claim 1 , wherein the wall comprises a wall material selected from the group consisting of aminoplast copolymer, an acrylic, an acrylate, and mixtures thereof.

11. A liquid detergent composition according to claim 10 , wherein the wall material comprises an aminoplast copolymer selected from the group consisting of melamine-formaldehyde, urea-formaldehyde, cross-linked melamine formaldehyde, and mixtures thereof.

12. A liquid detergent composition according to claim 1 , wherein the composition further comprises an external structurant.

13. A liquid detergent composition according to claim 1 , wherein the composition comprises a fatty acid or salt thereof in an amount of from about 0.1% to about 4% by weight of the composition.

14. A liquid detergent composition according to claim 1 , wherein the composition comprises no more than 0.1%, if any, of a cationic deposition aid polymer, excluding any cationic polymer that may be part of the coating of the encapsulate.

15. A detergent composition according to claim 1 , wherein the composition further comprises an adjunct selected from an enzyme, a brightener, a cleaning polymer, a soil release polymer, an amine, a hueing dye, or combinations thereof.

16. A detergent composition according to claim 15 , wherein the composition comprises a cleaning polymer comprising an alkoxylated polyalkyleneimine.

17. A method of treating a fabric, said method comprising the step of contacting a fabric with a detergent composition according to claim 1 .

18. A liquid detergent composition comprising:
A) from about 20% to about 50%, by weight of the detergent composition, of a surfactant system, wherein the surfactant system comprises:
a) a blend of anionic surfactants comprising anionic sulphate surfactant and an anionic sulphonate surfactant in a weight ratio of from about 1.5:1 to about 5:1;
b) a nonionic surfactant comprising an amine oxide; and
c) a cationic surfactant;
wherein the anionic to nonionic surfactant is present in weight ratio of from about 1:1 to about 3.6:1; and

B) from about 0.1% to about 5%, by weight of the composition, of encapsulates, wherein:
i) the encapsulates comprise a core and a wall at least partially surrounding the core;
ii) the core comprises a benefit agent; and
iii) the wall comprises a coating on an outer surface of the wall.

19. A liquid detergent composition according to claim 18 , wherein the coating comprises a cationic efficiency polymer selected from polyvinyl amines, polyvinyl formamides, polyallyl amines, copolymers thereof, and mixtures thereof, preferably polyvinyl formamide.

20. A liquid detergent composition according to claim 18 , wherein the composition further comprises an adjunct selected from an enzyme, a brightener, a cleaning polymer, a soil release polymer, a polyetheramine, a hueing dye, or combinations thereof.

21. A liquid detergent composition according to claim 8 , wherein the cationic efficiency polymer is selected from the group consisting of polysaccharides, cationically modified starch, cationically modified guar, polysiloxanes, poly diallyl dimethyl ammonium halides, copolymers of poly diallyl dimethyl ammonium chloride and vinyl pyrrolidone, acrylamides, imidazoles, imidazolinium halides, imidazolium halides, polyvinyl amines, polyvinyl formamides, pollyallyl amines, copolymers thereof, and mixtures thereof.

22. A liquid detergent composition according to claim 8 , wherein the cationic efficiency polymer comprises polyvinyl formamides.
