Bismuth subcarbonate

Bismuth subcarbonate (CAS 5892-10-4 ) is an inorganic bismuth salt used across pharmaceutical and cosmetic manufacturing as an opacifying agent and mild antimicrobial active. It functions primarily as a protective and preservative ingredient in topical and oral formulations. In pharmaceutical manufacturing, this compound is incorporated into antacid and gastrointestinal preparations, where it acts as a mucosal protectant and mild astringent in tablet and suspension form. Cosmetic formulators use it as an opacifier and white pigment in pressed powders, foundations, and skin-care creams requiring a matte or coverage effect for high-end beauty products. It also appears in wound-care and dermatological products where low-level antimicrobial activity against surface pathogens is required for effective skin protection and healing applications. Industrial ceramic and glass applications utilize this material as a precursor for bismuth oxide, which is highly relevant to specialty coatings procurement and advanced material science. The product is supplied as a fine white powder suitable for dry blending, tableting, and suspension manufacturing. Pharmaceutical-grade material is available to BP and Ph. Eur. specifications. These standards support regulated drug product manufacturing and quality documentation requirements. Technical-grade powder is also offered for non-pharmaceutical industrial applications where certification is not required. Contact us for supply of Bismuth subcarbonate Request Quote
