About

A white pearlescent pigment (bismuth oxychloride) used in decorative cosmetics, restricted in EU due to skin and eye irritation potential and respiratory concerns from powder forms.

Bismuth chloride oxide (CAS 7787-59-9) is used as a pearly luster pigment in decorative cosmetics including eye shadows, highlighters, and nail polishes. EU Regulation 1223/2009 Annex III restricts its use due to the potential for skin irritation (H315), serious eye irritation (H319), and respiratory irritation (H335). Bismuth oxychloride is considered safer than lead or arsenic-based pigments but requires appropriate concentration limits. The compound may cause mild irritation particularly in individuals with sensitive skin.
