    Abstract: A powder cosmetic provides an excellent finish and has an excellent usability while maintaining a hiding power, and exhibits an excellent capacity to be more transmissive of light in long wavelength regions (selective red light transmission capacity). The titanium dioxide powder is particles in which the apparent average particle diameter is 100 nm or more and less than 500 nm, the average crystallite diameter measured by x-ray diffraction is 15-30 nm, the specific surface area of 10-30 m2/g, and a ratio between the long diameter and short diameter of the shape (long diameter/short diameter) of 1.0-2.5, and the particles have a shape in which radially projecting needle-shaped projections are aggregated. The powder cosmetic incorporates the titanium dioxide powder.
