Description
Bismuth Oxychloride Product Overview
Bismuth oxychloride (BiOCl) is a white, fine crystalline powder made of thin, plate-like crystals. These platelets reflect light in a way that creates a soft, silky pearlescent effect, and they give a smooth, adherent feel on the skin.
Cosmetic formulators use it as a pearlescent pigment and skin-adhesion agent in eyeshadows, pressed powders, foundations, nail polish and lipsticks, listed as CI 77163. It is often combined with mineral pigments such as Titanium dioxide and mica. In materials research, its layered structure makes it a popular photocatalyst.
