Title:
PHOSPHORYLCHOLINE GROUP AND SILICONE GROUP-CONTAINING COPOLYMER, POWDER COATED WITH SAID COPOLYMER AND PRODUCTION METHOD THEREFOR, AND USE OF SAID COPOLYMER AND SAID POWDER IN COSMETICS
Document Type and Number:
WIPO Patent Application WO/2019/189608
Kind Code:
A1
Abstract:
This copolymer contains, as repeating units, (i) methacryloyloxyethyl phosphorylcholine and a derivative thereof, (ii) a silicone methacrylate, (iii) a substituted or unsubstituted straight-chain or branched alkyl methacrylate, a substituted or unsubstituted straight-chain or branched alkenyl methacrylate, or a substituted or unsubstituted cycloalkyl methacrylate, and (iv) methoxy polyethylene glycol methacrylate, and has excellent solubility in a less-polar oil. A cosmetic containing the copolymer and a cosmetic produced using a powder surface-treated with the copolymer have excellent skin affinity, moisture retention properties, water repellency, lubricative properties, and in addition, touch-proofness, which is resistance to being removed by touch. Therefore, the copolymer and the surface-treated powder are suitable for production of cosmetics.
