Publication number: 20220251393Abstract: An object is to reduce the occurrence of aggregation of an inorganic pigment that roughens the texture and dulls the color of a cosmetic containing the inorganic pigment. Porous pigment particles are provided which include cellulose or a cellulose derivative, and an inorganic pigment as main components. Also provided are a method for producing such particles, and a cosmetic containing such porous pigment particles. The particles are resistant to aggregation and are excellently dispersed in a base material to impart a color while improving the dullness problem. The particles of the present invention are porous particles that contain cellulose and have a wrinkle-like or fold-like uneven structure on the surface thereof (that is, have an appropriate amount of pores or voids). Thus, the particles of the present invention have soft and comfortable texture and are suitably added to cosmetics that are directly applied to the skin.Type: ApplicationFiled: July 31, 2020Publication date: August 11, 2022Applicant: NISSAN CHEMICAL CORPORATIONInventors: Takayuki IMOTO, Mutsuhiro KATSUYA
