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.

Photochromic color rendering regulatory composition and cosmetics

The present invention provides fundamental materials excellent in general purpose used for buildings, etc. as windows and interior and exterior walls of general buildings, houses, cars, etc., concretely, various laminates with the flip-flop effect (the effect of delicately changing in color, depending on the angles of view) and a decorative effect due to a colored mirror face, which are composed at least of a light-transmitting or light-intercepting base and a brightening pigment prepared by covering mica grains on the surfaces with titanium oxides including low-valent titanium oxides.

Laminates

A photochromic flesh-colored pigment comprising not less than 90 wt % of anatase type titanium oxide having photochromism and a process for producing a photochromic flesh-colored pigment comprising the steps of adding iron hydroxide (FeOOH) to a composition containing untreated anatase type titanium oxide as the main ingredient, and calcining the mixture at 750.degree. to 850.degree. C. It is possible to exhibit a flesh color with a single color with a single pigment and it is also possible to change the color depending upon the intensity of light.

Photochromic flesh-colored pigment and process for producing the same

The present invention concerns synthetic mica powder containing from 75 to 99% of the stoichiometrical composition of fluorine and/or having a shape in which the end face of a particle is laminated, a process for producing such synthetic mica powder, as well as cosmetics having synthetic mica powder blended therewith, in which the synthetic mica powder shows no leaching of fluorine ions and/or improved hold of oils due to lamination at the surface of the powder. Accordingly, in this invention, cosmetics excellent in extensibility, gloss, adherence and moldability, having an appearance of high chroma and of high stability and safety can be obtained.
