Abstract:
There is provided a spherical organic-inorganic composite particle having good biodegradability. The organic-inorganic composite particle according to the present invention includes 1 to 79% by weight of a silica component and 21 to 99% by weight of a biodegradable plastic. The organic-inorganic composite particle has an average particle diameter d1 of 0.5 to 25 μm, a true density of 1.03 to 2.00 g/cm3, and a sphericity of 0.80 or more. A cosmetic product including the organic-inorganic composite particle having such properties has excellent texture properties.
