Abstract
The present invention provides organic-inorganic composite particles having a suitable biodegradability. The organic-inorganic composite particles of the present invention include a silica component and a biodegradable plastic. The organic-inorganic composite particles have a mean particle diameter (d) ranging from 0.5 μm to 25 μm, an absolute specific gravity greater than 1.0 g/cm3 and equal to or smaller than 2.0 g/cm3, and a contact angle with water of 90° or less. A cosmetic product including the organic-inorganic composite particles has good texture characteristics.
