Title:
COMPOSITE PARTICLES, METHOD FOR PRODUCING COMPOSITE PARTICLES, AND COSMETIC
Document Type and Number:
WIPO Patent Application WO/2023/195402
Kind Code:
A1
Abstract:
The present invention provides composite particles in which rubber particles are attached to the surfaces of spherical organic resin particles, said composite particles being characterized in that the rubber particles are adhered to the organic resin particles with silica as a binder. The composite particles, in which rubber particles are attached to the surfaces of organic resin particles, are capable of imparting a soft feel and a smooth sense of use, extensibility, and an effect such as a natural finish due to light scattering properties, and the present invention also provides a method for producing said composite particles, as well as a cosmetic containing said composite particles.
