| abstract |
Block copolymers denoted AB from acrylic or methacrylic acid, the corresponding blocks being denoted by A, and from acrylate or alkyl methacrylate with the alkyl chain within C1-C10, the corresponding blocks being denoted by B. Said copolymer blocks are used as wetting and/or dispersing agents for solid particles in an essentially organic medium consisting of a solvent or a mixture of solvents solubilizing the block B. The invention also concerns solid particle dispersions using the above-defined block copolymers. It also concerns compositions, in particular cosmetic compositions, containing said dispersions. |
