Document Type and Number:
WIPO Patent Application WO/2020/054810
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a natural material-derived particle that is a natural material, soft and has excellent light scattering. Provided are: a particle that has protrusions and recesses on the surface thereof and comprises, as main components, a cellulose or a cellulose derivative and a clay mineral; and a method for producing said particle. Such a particle is useful for cosmetics because the particle is soft and has excellent light scattering, and particularly has an excellent defocus effect when mixed with cosmetics such as a foundation.
