摘要：

Provided are spherical organic-inorganic composite particles that exhibit good biodegradability. Organic-inorganic composite particles according to the present invention contain 1-79 wt% of a silica component and 21-99 wt% of a biodegradable plastic. The organic-inorganic composite particles have an average particle diameter d1 of 0.5-25 µm, a true density of 1.03-2.00 g/cm3, and a sphericity of 0.80 or greater. A cosmetic in which the organic-inorganic composite particles possessing such characteristics are blended exhibits superior touch feel characteristics.
