Abstract

Hair treatment compositions which can generate style benefits while giving good conditioning comprise a non-rigid, emulsion polymerised cross-linked silicone conditioning polymer having from about 0.05% to about 10% branched monomer units.

Claims

1. A hair treatment composition comprising from about 0.01 to about 50% by weight of a non-rigid, emulsion-polymerised cross-linked silicone conditioning polymer, in which the polymer has from about 0.05% to about 2% branched monomer units.

2. A composition according to claim 1, in which the silicone conditioning polymer is a cross-linked dimethicone.

3. A composition according to claim 1, in which the silicone conditioning polymer has from about 0.15% to about 0.6% branched monomer units.

4. A composition according to claim 1, in which the viscosity of the silicone conditioning polymer lies in the range 10⁶ to 10⁹ cst.

5. A composition according to claim 1 claims, in which the average particle size of the silicone conditioning polymer is less than 20 microns.

6. A composition according to claim 1 claims, which is a hair styling composition.

7. A composition according to claim 1, which is a shampoo comprising from about 0.1 to about 50% by weight of at least one surfactant selected from the group consisting of anionic, nonionic, amphoteric surfactants and mixtures thereof.

8. A composition according to claim 1, which is a conditioning composition containing one or more conditioning agents.

9. A composition according to claim 1, comprising at least one of a deposition aid and a fatty alcohol material.

10. A composition according to claim 9, comprising from about 0.01 to about 5% by weight of a deposition aid which is a cationic polymer selected from the group consisting of hydroxyalkyl cellulose ethers, cationic guars and cationic polyacrylamides.
