INORGANIC COMPOSITE POWDER AND COSMETIC COMPRISING THE SAME |
摘要 |
<p>An inorganic composite powder has a satisfactory covering capability and a feeling of transparency, and a cosmetic blended the inorganic composite powder can cover such defects as blots and freckles on the human skin and insure a natural appearance. The inorganic composite powder comprises two or more types of inorganic oxides having different refractive indexes respectively and sequentially laminated from the one with the highest refractive index at the bottom on a scaled substrate, wherein the difference in the refractive index between the utmost outer layer and adjoining inner layer is 0.6 or below, or the thickness of at least one of the second or higher inorganic oxide layers is within +/- 20% of the value d given by the equation: <MATH> wherein lambda indicates a wavelength of visual light, X indicates an odd integer, and n indicates a refractive index of the inorganic oxide. In the cosmetic according to the present invention, the refractive index of the inorganic oxide use for forming the utmost outer layer of the inorganic composite powder is preferably 1.5 or below.</p> |
