Document Type and Number:
WIPO Patent Application WO/2023/234072
Kind Code:
A1
Abstract:
[Problem] To provide fine particles having excellent biodegradability and texture by coating biodegradable cellulose particles with silicone that imparts slidability, water repellency, and the like to form composite particles. [Solution] The present invention provides: composite particles which are characterized by comprising particles of cellulose or a cellulose derivative and polyorganosilsesquioxane attached to the surfaces of the particles, wherein the polyorganosilsesquioxane is a polymer of organotrialkoxysilane in an amount of 3-80 parts by mass per 100 parts by mass of the particles; a method for producing the composite particles; and a cosmetic containing the composite particles.
