  • Publication number: 20240058256
    Abstract: Provided are silicone elastomer particles that have higher oil absorbency than conventional products and are less prone to aggregation, making the particles superior in handling workability as a cosmetic raw material and imparting a superior tactile sensation and feel during use to a cosmetic product. Specifically, silicone elastomer particles, having a structure in which at least two silicon atoms in a silicone elastomer particle are crosslinked by a divalent organic group having a partial structure formed by radical polymerization of vinyl acetate, as expressed by —{CH2—CH(COOCH3)}t— (where t is 1 or more), as well as a use thereof, are provided. In particular, the silicone elastomer particles have a crosslinked structure that is active with respect to biodegradability. Therefore, primary particles thereof are expected to have a property of disintegrating with the generation of non-crosslinked siloxane molecules due to a decomposition reaction of microorganisms and the like in the natural world.
