What it is
Bismuth Oxychloride is a white powder that seldom occurs in nature. It is usually made by combining bismuth, a by-product of lead and copper metal refining, with chloride and water.
What it does
Bismuth Oxychloride adheres well to skin, helping makeup stay on longer.
It also gives skin a silky feel and either a white shimmer or pearlescent matte finish. The glow reflects light away from the skin, helping to hide wrinkles and fine lines.
It is also used as a colouring agent: it imparts a white colour to cosmetics and personal care products.
In addition, it is an absorbent agent and a thickener.
Bismuth Oxychloride has a unique unique crystalline structure. That means that its crystal can get stuck into the pores and irritate skin. This can cause rednes, itching, and aggravate rosacea.
Bismuth Oxychloride is not allowed to be used in lip products.
