Abstract

Disclosed are hair shampoo compositions which provide cleaning and styling performance, which comprise dispersed water insoluble, polymer latex particles, wherein the polymer latex particles have a selected glass transition temperature (Tg) of between about −20° C. and about 10° C. The shampoo compositions will generally contain one or more compatible surfactants, one or more optional materials, and a water or water-containing carrier as an aqueous carrier.

Claims

1. Shampoo compositions comprising:

(A) from about 0.5% to about 50% by weight of synthetic surfactant;

(B) from about 0.05% to about 25% by weight of dispersed water insoluble polymer latex particles having a glass transition temperature of from about −

20°

C. to about 10°

C.; and

(C) water.

2. The shampoo compositions of claim 1 wherein the glass transition temperature of the polymer latex particles is from about −

15°

C. to about 8°

C.

3. The shampoo compositions of claim 2 wherein the glass transition temperature of the polymer latex particles is from about −

10°

C. to about 5°

C.

4. The shampoo compositions of claim 1 wherein the water insoluble polymer latex particles have an average particle diameter of less than about 4 μ

m, and are selected from the group consisting of nonionic polymers, anionic polymers, cationic polymers, amphoteric polymers and mixtures thereof.

5. The shampoo compositions of claim 4 wherein said compositions comprise from about 0.05% to about 15% by weight of the latex polymer particles.

6. The shampoo compositions of claim 5 wherein said compositions comprise from about 0.5% to about 7% by weight of the latex polymer particles.

7. The shampoo compositions of claim 4 wherein the polymer latex particles have an average particle diameter of from about 0.005 μ

m to about 1 μ

m.

8. The shampoo compositions of claim 1 wherein said compositions comprise from about 20% to about 95% by weight of water.

9. The shampoo compositions of claim 8 wherein said compositions comprise from about 60% to about 85% by weight of water.

10. The shampoo compositions of claim 7 wherein the synthetic surfactant is an anionic surfactant, nonionic surfactant or mixtures thereof.

11. The shampoo compositions of claim 8 wherein said composition comprises from about 5% to about 25% by weight of the synthetic surfactant.
