FATTY ACID CALCIUM SALT PARTICLES AND COSMETICS
The invention relates to particles of a calcium salt of a fatty acid having 12 to 22 carbon atoms, wherein the median size is 4.0 µm to 15.0 µm, the particle size digest A expressed by the following equation (1) satisfies the relation A≤2.0, and the average thickness is 350 to 800 nm. ParticlesizedigestA=D90−D10/D50 (Here, 4.0≤D50≤15.0.)D10: the 10% cumulative size (µm) of the fatty acid calcium salt particles on a volumetric basisD50: the median size (µm) of the fatty acid calcium salt particles on a volumetric basisD90: the 90% cumulative size (µm) of the fatty acid calcium salt particles on a volumetric basis.
