  • Applications

    Bismuth Subgallate is used primarily in cosmetics and personal care as an astringent and odor-control ingredient in products such as powders and topical preparations; it also serves as a mild antimicrobial and drying agent in cosmetic formulations. In pharmaceutical contexts, it is considered as an astringent and mild antiseptic component for topical preparations. In household products, it can be used as an antimicrobial and odor-control additive in powders, cleaners, and sanitation products. In industrial manufacturing, it is occasionally evaluated as a stabilizer or processing aid in polymers and coatings to improve thermal stability and chemical resistance of plastics and paints.
