Document Type and Number:
Japanese Patent JP7334376
Kind Code:
B2
Abstract:
A composition includes particles of a cellulose derivative and a surface treatment compound. The particles of the cellulose derivative have an average particle size from 0.08 µm to 100 µm. The surface treatment compound is an organic compound having a long-chain alkyl group and/or an inorganic powder. The inorganic powder has an average particle size of 1/3 or less of the average particle size of the particles of the cellulose derivative. A cosmetic composition includes the composition. A method for producing the composition includes mixing the particles of the cellulose derivative and the surface treatment compound. In the mixing, the particles of the cellulose derivative and the surface treatment compound are dry-mixed.
