What is Bismuth subcarbonate?
Bismuth subcarbonate (CAS 5892-10-4) is an inorganic bismuth salt used in pharmaceutical and cosmetic manufacturing as an opacifying agent and mild antimicrobial active.
Where is Bismuth subcarbonate used?
- Pharmaceuticals: mucosal protectant and mild astringent in antacid and gastrointestinal tablets and suspensions
- Cosmetics: opacifier and white pigment in pressed powders, foundations and skin-care creams
- Wound care and dermatological products: low-level antimicrobial activity against surface pathogens
- Ceramics and glass: precursor for bismuth oxide
- It functions as a protective and preservative ingredient in topical and oral formulations.
Good to know: Pharmaceutical-grade material meets BP and Ph. Eur. specifications; technical-grade powder is offered for non-pharmaceutical industrial applications where certification is not required.
