SURFACE-COATED POWDER AND COSMETIC CONTAINING SAID POWDER

摘要

A surface-coated powder which comprises a powder coated with a metal oxide-organopolysiloxane hybrid wherein an organopolysiloxane and a metal oxide form a composite at a molecular level. The surface-coated powder is prepared by coating a powder with a metal oxide-organopolysiloxane hybrid sol, to thereby form a thin film of the above hybrid on the surface of the powder. The metal oxide of the above metal oxide-organopolysiloxane hybrid is preferably one or more of metal oxides selected from among a titanium oxide, a zirconium oxide and silicon dioxide. The above metal oxide-organopolysiloxane hybrid can have a controlled water repellency by the adjustment of the proportion of the metal oxide to the organopolysiloxane, and thus the water repellency of the powder can be controlled with ease by the adjustment of the above proportion. A cosmetic containing the above surface-coated powder is excellent in natural appearance and in the feeling during the practice of application.
