(A) an unsaturated monomer having a carbosiloxane dendrimer structure; And (B) an unsaturated monomer having at least one hydrophilic group in the molecule. The content of unsaturated monomers having a carboxylic acid dendrimer structure is in the range of 35 to 50 mass% of the total monomer units of the copolymer. The present invention is also a cosmetic raw material containing such components, as well as liquid compositions, surface treatment agents and powder compositions comprising the copolymer. |
