Bismuth Oxychloride
What is Bismuth Oxychloride?
Bismuth oxychloride is an inorganic compound, chemically BiOCl, formed as a fine, white, platelet-shaped crystalline powder exhibiting a distinctive pearlescent sheen. Synthetically produced from bismuth chloride and sodium hydroxide, it originates from mineral sources but is purified for purity in formulations. Commonly used in the makeup category of cosmetics, including eyeshadows, highlighters, blushes, and nail polishes, it serves primarily as a pearlescent agent and colorant. Its unique layered structure enables light reflection and refraction, producing a luminous, silky glow on the skin. This optical effect enhances product aesthetics, improves spreadability, and promotes even adherence for durable wear, while maintaining a neutral tint that blends seamlessly with other pigments.
