  • Applications

    Bismuth oxychloride (CAS 7787-59-9) is used primarily as a white pearlescent pigment with real-world applications across several industries: cosmetics/personal care (powders, eye makeup, and nail polish) to impart a pearlescent effect; coatings and inks (decorative coatings and printed materials) for aesthetic embellishment; plastics/polymers (pigment additives for plastics and composites to enhance appearance); and in advanced materials research, where BiOCl-based systems are studied for photocatalysis and environmental remediation. In industry, these applications are typically realized as pigment-based colorants, with formulation and regulatory limits governed by local regulations.
