Abstract
The present invention is a photochromic color rendering regulatory composition and cosmetics characterized in comprising of an inorgamic compound having photochromic property. Photochromic inorganic compounds colors the composition and cosmetics suitably according to the change in light intensity. Therefore, composition and cosmetics of the present invention can regulate appropriate the tendency in which the color of objects looks whiter when the light intensity is strong and it looks blacker when it is weak, and can always provide constant color rendering.
