Abstract

Described are personal care compositions, comprising an aqueous dispersion comprising an ethylene acrylic acid copolymer and a least one cosmetically acceptable surfactant, emollient, or cosmetic active.

Claims

1. A personal care composition, comprising:

a tertiary amine substituted hydroxyethylcellulose selected from the group consisting of N,N-diethylaminoethyl hydroxyethylcellulose, N,N-dimethylaminoethyl hydroxyethylcellulose, N,N-diisopropylaminoethyl hydroxyethylcellulose, N,N-dimethylaminopropyl hydroxyethylcellulose, N-ethyl piperidine hydroxyethylcellulose, N-ethyl morpholine hydroxyethylcellulose, N-ethyl pyrrolidine hydroxyethylcellulose, and mixtures thereof; and

at least one cosmetically acceptable surfactant, emollient, or cosmetically active agent.

2. The personal care composition of claim 1, wherein the tertiary amine substituted cellulose derivative is present in a range from about 5 wt % to about 40 wt % by weight of the aqueous dispersion.

3. The personal care composition of claim 1, further comprising a silicone, provided that the silicone is not in the aqueous dispersion.

4. The personal care composition of claim 3, wherein the silicone is present in a range from about 0.1 wt % to about 5 wt % by weight of the personal care composition.

5. The personal care composition of claim 1, wherein the surfactant is present and is a detergent surfactant.

6. The personal care composition of claim 1, wherein the surfactant is present and is a nonionic surfactant.

7. The personal care composition of claim 1, wherein the personal care composition is a shampoo, a rinse-off conditioner, a leave-in conditioner, or a body wash.

8. The personal care composition of claim 1, wherein the tertiary amine substituted cellulose derivative is present in a range from about 15 wt % to about 25 wt % by weight of the aqueous dispersion.

9. The personal care composition of claim 4, wherein the silicone is present in a range from about 0.75 wt % to about 3 wt % by weight of the personal care composition.

10. The personal care composition of claim 9, wherein the silicone is present in a range from about 1 wt % to about 2 wt % by weight of the personal care composition.

11. The personal care composition of claim 5, wherein the detergent surfactant is present in a range from about 1 wt % to about 25 wt % by weight of the personal care composition.

12. The personal care composition of claim 11, wherein the detergent surfactant is present in a range from about 5 wt % to about 20 wt % by weight of the personal care composition.

13. The personal care composition of claim 12, wherein the detergent surfactant is present in a range from about 7 wt % to about 18 wt % by weight of the personal care composition.

14. The personal care composition of claim 1, wherein the surfactant is present and is a cationic surfactant.

15. The personal care composition of claim 14, wherein the cationic surfactant is present in a range from about 0.1 wt % to about 10 wt % by weight of the personal care composition.

16. The personal care composition of claim 15, wherein the cationic surfactant is present in a range from about 1 wt % to about 4 wt % by weight of the personal care composition.

17. The personal care composition of claim 1, wherein the tertiary amine substituted hydroxyethylcellulose is N,N-diethylaminoethyl hydroxyethylcellulose.
