Abstract

The present invention provides an iron oxide-coated layered silicate pigment that has no interference color, strongly exhibits the color inherent in iron oxide, and is excellent in gloss. The pigment of the present invention is an iron oxide-coated layered silicate pigment comprising a layered-silicate plate particle as base, and an iron oxide coated on the plate particle; wherein the iron oxide does not coat the surface portion of the plate particle or the iron oxide is localized on the edge portion rather than the surface portion of the plate particle. As the iron oxide, at least one kind selected from black iron oxide (FeO) and red iron oxide (FeO) can be used preferably. As the layered silicate, a mica-group layered silicate can be used preferably. The iron oxide-coated layered silicate pigment of the present invention can be incorporated into cosmetic preferably.
