WIPO Patent Application WO/2022/071143
Kind Code:
A1
Abstract:
The present invention relates to a cosmetic comprising fatty acid magnesium salt particles and titanium oxide particulates. In the fatty acid magnesium salt particles, the fatty acid contains from 12 to 22 carbon atoms, the aspect ratio expressed by the following equation (1) is from 1.0 to 2.0, and the average thickness is from 250 to 600 nm. Equation (1): Aspect ratio = major axis diameter of particle (µm)/minor axis diameter of particle (µm).
