<p>Problem: To provide a novel organopolysiloxane copolymer that, compared with conventional polyether-modified silicones and silicone-based alternating copolymers, has superior compounding stability in cosmetics and feeling to touch improvement characteristics, can be used in combination with a wide range of cosmetic composition compounding components, and that has superior surface activity. Means To Resolve the Problems: An AB-type organopolysiloxane copolymer having a silylalkyl group having a carbosiloxane dendrimer structure on one terminal and a hydrophilic segment on the other terminal of the molecular chain; and a method for manufacturing the same. A surfactant and a powder treatment agent comprising the organopolysiloxane copolymer; and a topical composition and a cosmetic composition comprising the organopolysiloxane copolymer.</p> |
