Abstract

A cosmetic shampoo composition comprises in a carrier for application to the hair at least one detergent and at least one graft cationic copolymer of N-vinylpyrrolidone, dimethylaminoethyl methacrylate and polyethylene glycol.

Claims

1. A cosmetic shampoo composition for treating the hair comprising a cosmetic carrier for application to the hair, at least one detergent in an amount between 0.2 and 25 weight percent based on the total weight of said composition and at least one graft cationic polymer of

a. 3 to 95 weight percent N-vinylpyrrolidone,

b. 3 to 95 weight percent dimethylaminoethyl methacrylate, and

c. 2 to 50 weight percent polyethylene glycol,

said graft cationic copolymer being present in an amount between 0.1 and 5 weight percent based on the total weight of said composition and having a molecular weight ranging between 10,000 and 1,000,000.

2. The composition of claim 1 which also includes an adjuvant selected from the group consisting of a fatty amide, an amine oxide, a fatty ester and a perfume.

3. The composition of claim 1 wherein the said graft cationic copolymer is quaternized with a quaternization agent.

4. The composition of claim 3 wherein said quaternization agent is selected from the group consisting of dimethyl sulfate, diethyl sulfate, benzyl chloride, benzyl iodide and benzyl bromide.

5. The composition of claim 1 wherein said graft cationic copolymer has a molecular weight between 15,000 and 500,000.

6. The composition of claim 1 wherein said detergent is selected from the group consisting of an anionic, a nonionic, a cationic and an amphoteric detergent.

7. The composition of claim 1 wherein the carrier is an aqueous carrier and having a pH between 4 and 7.

8. The composition of claim 1 wherein the carrier is an aqueous carrier anol having a pH between 4.5 and 6.5.
