Abstract:
1. A method for depositing a polymer onto a hair or skin surface comprising the step of applying a composition comprising said polymer onto the surface, wherein the composition comprises a di-block (block A)-(block B) copolymer (a), comprising two blocks A and B, wherein block A is a polyanionic block and comprises repeating units deriving from monomers selected from the group consisting of: alpha-ethylenically-unsaturated monomers comprising a phosphate or phosphonate group, alpha-ethylenically-unsaturated monocarboxylic acids, monoalkylesters of alpha-ethylenically-unsaturated dicarboxylic acids, monoalkylamides of alpha-ethylenically-unsaturated dicarboxylic acids, alpha-ethylenically-unsaturated compounds comprising a sulphonic acid group, and salts of alpha-ethylenically-unsaturated compounds comprising a sulphonic acid group, block B is a neutral block in the pH conditions of the formulation, and block A and block B comprise units deriving from a mono-alpha-ethylenically-unsaturated monomer.
