<p>An inorganic composite powder having a satisfactory covering ability and a feeling of transparency, and a cosmetic comprising the inorganic composite powder which can cover a defect on a human skin such as a wrinkle, a melasma, an ephelis or the like, while maintaining a natural feeling of appearance. The inorganic composite powder comprises a substrate in a scale form and two or more inorganic oxides laminated thereon in decreasing order of refractive index, wherein the difference in refractive index between an inorganic oxide of an outermost layer and that of a layer inside the layer is 0.6 or less, or the thickness of at least one layer of the second layer and the layers under the layer in said inorganic oxide layers falls within ±20 % of the value d defined by the formula: d = (μ x X/4)/n wherein μ, X and n represent a wave length of a visible ray, an odd integer and a refractive index of an inorganic oxide of the layer, respectively. The cosmetic preferably utilizes an inorganic composite powder having an outermost layer comprising an inorganic oxide having a refractive index of 1.5 or less.</p> |
