Title:
RADICAL COPOLYMER COMPOSITION, PRODUCTION METHOD THEREFOR, AND COSMETIC OR COSMETIC INGREDIENT CONTAINING RADICAL COPOLYMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/138330
Kind Code:
A1
Abstract:
[Problem] To provide a monomer composition and a production method therefor, with which there are no safety concerns in the case of use as a cosmetic ingredient or the like and a decline in the quality of gelling or the like is not caused. [Solution] A radical copolymer composition which contains a) radical polymerisable monomers that include in the molecule a radical-copolymerisable organic group and an organosilicon-containing organic group, and b) a radical copolymer of radical polymerisable monomers other than component a), wherein the total concentration of a polymerisation inhibitor in relation to the total mass of the radical copolymer and the polymerisation inhibitor is 50 mass ppm or less; and a production method for said radical copolymer composition.
