Silica-cerium oxide composite particles, preparation method thereof and resin composition and cosmetic composition containing the same |
| abstract |
A powder of silica-cerium oxide composite particles useful as a sunscreen agent in a resin composition or as a sunscreen agent in a cosmetic composition is proposed. Cerium oxide-based composite particles consist of cerium oxide and 5 to 60% by weight of amorphous silica, calculated as SiO 2 . Multiparticulates are prepared by adding sodium silicate and an inorganic acid to an aqueous slurry containing a precipitate of cerium hydroxide to precipitate amorphous silica on the cerium hydroxide particles, followed by drying and calcining the particles separated from the reaction mixture. . Cosmetic compositions of various formulations in combination with silica-cerium oxide composite particles are disclosed. |
