Cosmetics containing a multi-functional composite powder

摘要

This invention provides cosmetics containing a multi-functional composite powder having the properties of (a) an excellent adhesiveness, (b) an excellent extendability, (c) an appropriate glossy effect, (d) a homogeneous cosmetic film, (e) an appropriate covering capability, (f) a cosmetic film not causing a white masking, (g) a high compatibility between a color appearance of cosmetics and a color tone of the cosmetic film, (h) an excellent soft-focusing capability, (i) an excellent ultraviolet protective effect, and the like. The multi-functional composite powder is constituted by a scale-like base material, a group of particles comprising at least fine particles of titanium dioxide deposited on a surface of the scale-like base material, and a thin film of a composite oxide containing titanium and iron coated thereon.

主权项

1. A cosmetic composition containing a multi-functional composite powder wherein the multifunctional composite powder is constituted by:
(i) a scale-like base material, (ii) a group of particles disposed on and covering only a part of a surface of the scale-like base material, the group of particles comprising at least particles of titanium dioxide having an average particle diameter of from 0.1 to 0.4 μm, and (iii) a thin film of a composite oxide of titanium and iron on and coating a part of the surface of the scale-like base material, wherein
the thin film of the composite oxide of titanium and iron coats the part of the surface of the scale-like base material that is not covered by the group of particles,the thin film has a thickness smaller than the average diameter of the particles of the group of particles, andthe particles of the group of particles are not completely covered by the thin film so that visible light incident on the particles is scattered.
