SHAPED SOLID PARTICLES COMPRISING THERMOPLASTIC COPOLYMER, PRODUCTION METHOD FOR SAME, AND COSMETIC INCLUDING SAME

Abstract

Provided are molded solid particles made of a thermoplastic copolymer having a silicon-containing organic group, which has excellent solubility in solvents acceptable for cosmetic materials and excellent handling properties, and can be mass-produced by an industrial production process, as well as uses and production methods thereof. The molded solid particles comprise a thermoplastic copolymer made by copolymerizing: (a1) an unsaturated monomer having one radical polymerizable organic group and one silicon-containing organic group in the molecule; and (a2) an unsaturated monomer having one radical polymerizable vinyl group in the molecule, which is different from component (a1). The major axis of the particles is less than 10 mm. Also provided are a use of the molded solid particles, and a production method of the molded solid particles including a stranding step and a cutting step.
