Document Type and Number:
WIPO Patent Application WO/2022/113560
Kind Code:
A1
Abstract:
Provided are: a pigment through which light in a warm color region can pass preferentially and which has high hiding power and is mainly used in cosmetic applications; a method for producing the pigment; and a method for using the pigment. The pigment comprises particles each containing a calcium-titanium composite oxide as a main component, in which it is confirmed that regions each having a paler color than the color of a region surrounding thereof are scattered in a dot-like form in the particles when the particles of the calcium-titanium composite oxide in the pigment are observed in a transmission electron microscopic image at a magnification of 100,000×, and the true density of the pigment is 3500 kg/m3 to 3790 kg/m3, inclusive.
