SYNTHETIC ORGANIC PARTICLES, PROCESS FOR THE PRODUCTION OF THE SAME, AND USE THEREOF

Synthetic organic particles each constituted of a core made from an organic polymer and a surface layer formed from a methacrylate resin on the surface of the core. In one of the particles, the core is made from a copolymer comprising 80 to 99 weight percent of a lower alkyl acrylate and 1 to 20 wei...

Beschreibung
Zusammenfassung:	Synthetic organic particles each constituted of a core made from an organic polymer and a surface layer formed from a methacrylate resin on the surface of the core. In one of the particles, the core is made from a copolymer comprising 80 to 99 weight percent of a lower alkyl acrylate and 1 to 20 weight percent of a polyfunctional vinyl monomer to exhibit rubberlike elasticity, while in another of the particles, the core is made from a copolymer of a reactive benzotriazol compound and a (meth)acrylic monomer to exhibit an ultraviolet absorbing activity. These synthetic organic particles can be suitably added to cosmetics to impart a feeling of creamy softness and an ultraviolet screening power to them.
