Abstract: PCT No. PCT/JP94/01609 Sec. 371 Date Apr. 1, 1996 Sec. 102(e) Date Apr. 1, 1996 PCT Filed Sep. 28, 1994 PCT Pub. No. WO95/09895 PCT Pub. Date Apr. 13, 1995The present invention is directed to ultraviolet shielding composite fine particles having transparency in a visible light region, comprising (a) matrix particles comprising an aggregate of primary particles having an average particles diameter of from 0.001 to 0.3 mu m, said aggregate being formed while retaining the shapes of the primary particles; and (b) daughter particles having an average particle diameter of from 0.001 to 0.1 mu m, said daughter particles being dispersed in and supported by said matrix particles, wherein said daughter particles have a smaller band gap energy than that of particles constituting said matrix particles, and possess capability of absorbing ultraviolet light. The composite fine particles are produced by preparing a liquid mixture containing a mixture comprising starting materials for matrix particles and for daughter particles; forming droplets from the liquid mixture; and drying the formed droplets and/or pyrolyzing starting materials for pyrolysis therein. The cosmetics of the present invention contain the above composite fine particles.

Abstract: PCT No. PCT/JP96/00593 Sec. 371 Date Aug. 27, 1997 Sec. 102(e) Date Aug. 27, 1997 PCT Filed Mar. 7, 1996 PCT Pub. No. WO96/28137 PCT Pub. Date Sep. 19, 1996The present invention is directed to ultraviolet shielding composite fine particles having transparency in a visible light region include (a) matrix particles comprising an aggregate of primary particles having an average particle diameter of from 0.001 to 0.3 mu m, the aggregate being formed while the primary particles retain their shapes; and (b) daughter particles having an average particle diameter of from 0.001 to 0.1 mu m, the daughter particles being dispersed in and supported by the matrix particles. In the composite fine particles, the daughter particles have a smaller band gap energy than the particles constituting the matrix particles and are capable of absorbing ultraviolet light, and the resulting ultraviolet shielding composite fine particles have substantially no catalytic activity.

Abstract: A fluorine-modified silicone derivative having a polymerization degree of from 1 to 400 and containing at least one siloxane unit represented by formula (1): wherein R represents an aliphatic straight-chain or branched hydrocarbon group having 1 to 20 carbon atoms or an alicyclic or aromatic hydrocarbon group having 5 to 10 carbon atoms; and m represents 0 or an integer of from 1 to 10; a process for preparing the same; and a cosmetic containing the same are disclosed. The fluorine-modified silicone derivative exhibits high water- and oil-repellency to provide cosmetics which wear long and have a good feel on use.
