A solid particle of organosilicon-functional co-polymer, manufacturing process thereof, and cosmetics comprising said solid particle

Abstract

Provided is a solid particle consisting essentially of organosilicon-functional co-polymer polymerized from a monomer composition. The monomer composition consists essentially of (A) one or more unsaturated polymerizable monomer(s) having at least one organosilicon functionality and one polymerizable group in the molecule and (B) one or more unsaturated polymerizable monomer(s) containing no or one silicon atom and having one polymerizable group in the molecule. The mass ratio of monomer (A) to monomer (B) ranges from 35:65 to 70:30 in the monomer composition. The long size in three directions for the solid primary particle ranges from 0.1 to 5,000 μm. A manufacturing process of the solid particle, use of the solid particle as a cosmetic ingredient, as well as a cosmetic composition comprising the solid particle and the production method thereof are also provided.

Dependencies are inferred from the claim text.
