POLYETHER-MODIFIED ORGANOPOLYSILOXANE, DIORGANOPOLYSILOXANE-POLYETHER BLOCK COPOLYMER, THEIR PRODUCTION METHODS, AND COSMETIC PREPARATION |
摘要 |
(Problem) To provide a novel polyether-modified organopolysiloxane and a novel diorganopolysiloxane-polyether block copolymer that are more resistant to oxidation than the heretofore existing polyoxyalkylene-modified organopolysiloxanes and that are thus more resistant to producing allergenically antigenic oxidation products during elapsed time in storage. Also, to provide methods of producing this novel polyether-modified organopolysiloxane and novel diorganopolysiloxane-polyether block copolymer. (Solution) Organopolysiloxane that is modified by silicon-bonded polyglycidyl ether or glycidyl ether/alkylene oxide copolymer; diorganopolysiloxane-polyglycidyl ether block copolymer; a method of producing the preceding by a hydrosilylation reaction between organohydrogenpolysiloxane and polyglycidyl ether having a terminal double bond or a glycidyl ether/alkylene oxide copolymer having a terminal double bond; and a cosmetic that contains this modified organopolysiloxane or diorganopolysiloxane-polyglycidyl ether block copolymer. |
