Title:
ORGANOPOLYSILOXANE GRAFT POLYMER
Document Type and Number:
Japanese Patent JP2014177447
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an organopolysiloxane graft polymer having an anionic group which is optimal for a hairdressing method for fixing a shaped hair style by cooling the temperature of the hair to less than 50°C after shaping the hair at a hair temperature of 50°C or more and has an excellent feeling of the hair after setting and has excellent set retainability under high humidity.SOLUTION: There is provided an organopolysiloxane graft polymer which has an organopolysiloxane segment as a main chain and a copolymer segment as a side chain derived from an unsaturated monomer containing a repeating unit derived from an unsaturated monomer having carboxylic acid or a salt thereof, wherein the content of the organopolysiloxane segment in the organopolysiloxane graft polymer is 35 to 59 mass%, the content of the repeating unit derived from the unsaturated monomer having the carboxylic acid or the salt thereof is 4 to 17 mass%, the content of the repeating unit derived form an unsaturated monomer having a glass transition temperature of 150°C or more (excluding the unsaturated monomer having the carboxylic acid or the salt thereof) is 14 mass% or less when a homopolymer is formed, and the organopolysiloxane segment has a number-average molecular weight of 8000 or more and 200000 or less.
