Abstract
A pigment containing particles surface treated with N-acylglycine hydroxyaluminum and/or N-acyl-N-methylglycine hydroxyaluminum, and a pigment dispersion which contains such surface treated particles and a cosmetically acceptable oily material, having excellent dispersion stability and versatility (ease of dispersion and wide range of usage), because the particles are easily and uniformly dispersed in a short period of time at a high concentration in such a cosmetically acceptable oily material, thus a cosmetic product is thereby stable as an emulsion and has better usage than existing products.
