BLOCK POLYMER AND COSMETIC COMPOSITION CONTAINING THE SAME |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a cosmetic composition comprising a novel block polymer. SOLUTION: A novel block polymer having a specific chemical structure and a cosmetic composition containing the same are provided. The novel block polymer is a polymer wherein the first block is selected from (a) a block having a Tg of≥40°C, (b) a block having a Tg of≤20°C and (c) a block having a Tg of 20°C-40°C and the second block is selected from the categories (a), (b) and (c) but differently from the first block. Preferable monomers suitable for both the first and the second blocks are (meth)acrylate derivatives. COPYRIGHT: (C)2008,JPO&INPIT |
