Abstract

Fabric treatment compositions that include benefit agent capsules and diaminostilbene brightener. Methods of using the same. Wash water containing such compositions.

First claim

What is claimed is:

1. A fabric treatment composition comprising:
from about 0.01 wt % to about 10 wt % of the fabric treatment composition of
a) benefit agent capsules wherein the benefit agent capsules comprise a shell material encapsulating a core material,
wherein said shell material is derived from polyvinylalcohol and a shell component,
wherein said shell component is polyacrylate, and
wherein the level of polyvinylalcohol is from about 0.01 to about 20%, by weight of the benefit agent capsules;

said core material comprises perfume raw materials, wherein the perfume raw materials are present in an amount of from 20% to 98%, by weight of the benefit agent capsules;

b) from about 0.1% to about 0.5% by weight of the fabric treatment composition of a diaminostilbene brightener having the formula the group consisting of

wherein M is a suitable cation.

2. The fabric treatment composition according to claim 1 wherein the polyvinylalcohol has a degree of hydrolysis of about 70% to about 99%.

3. The fabric treatment composition according to claim 1 wherein the polyvinylalcohol as a 4 wt % solution in water has a viscosity of from about 2 mPa·s to about 150 mPa·s.

4. The fabric treatment composition according to claim 1 wherein the weight ratio of polyvinylalcohol to brightener is from about 1/1 to about 1/5000.

5. The fabric treatment composition according to claim 1 wherein the weight ratio of diaminostilbene brightener to benefit agent capsules is from 50/1 to 1/500.

6. The fabric treatment composition according to claim 1 wherein the level of polyvinylalcohol is from about 0.05 to about 10%, by weight of the benefit agent capsules.

7. The fabric treatment composition according to claim 1 wherein the level of polyvinylalcohol is from about 0.1 to about 2% by weight of the benefit agent capsules.

8. The fabric treatment composition according to claim 1 wherein the fabric treatment composition further comprises a surfactant selected from nonionic, anionic, cationic, zwitterionic surfactants and combinations thereof.

9. The fabric treatment composition according to claim 1 wherein the level of surfactant is from about 1 wt % to about 70 wt %, of the fabric treatment composition.

10. The fabric treatment composition according to claim 1 wherein the level of surfactant is from about 10 wt % to about 40 wt % of the fabric treatment composition.

11. The fabric treatment composition according to claim 1 wherein the level of surfactant is from about about 15 wt % to about 30 wt % of the fabric treatment composition.

12. The fabric treatment composition according to claim 1 wherein the diaminostilbene brightener is

13. The fabric treatment composition according to claim 1 , wherein the fabric treatment composition is a laundry detergent composition.

14. The fabric treatment composition according to claim 1 , wherein the fabric treatment composition is a liquid.

15. The fabric treatment composition according to claim 1 , wherein the fabric treatment composition further comprises from about 1% to about 50%, by weight of the fabric treatment composition, of anionic surfactant.

16. The fabric treatment composition according to claim 1 , wherein the fabric treatment composition further comprises from about 10% to about 40%, by weight of the fabric treatment composition, of anionic surfactant.

17. The fabric treatment composition according to claim 1 , wherein the fabric treatment composition further comprises nonionic surfactant.

18. The fabric treatment composition according to claim 1 , wherein the fabric treatment composition further comprises enzymes.
