Abstract
The porous-cellulose particles according to the present invention are constituted by gathered crystalline celluloses having a type I crystal form including a glucose molecule as a constitutional unit. That is, porous-cellulose particles having high sphericity have been achieved from a natural raw material. The porous-cellulose particles have an average particle diameter of 0.5 to less than 50 μm, a specific surface area of 50 to 1000 m/g, and a sphericity of 0.85 or more. Cosmetic products containing such porous-cellulose particles have excellent texture properties.
