  • Applications

    Azelaic acid, dipotassium salt, CAS number: 19619-43-3 is a potassium salt of azelaic acid with multiple industrial and cosmetic applications. In cosmetics and personal care, it serves as an azelate source and can help adjust pH in formulations; in polymers and plastics, it acts as a diacid building block for the synthesis of aliphatic polyesters and polyurethanes, imparting stability and flexibility; in coatings and inks, it is used as a diacid monomer for polyester/alkyd resins used in paints and printing inks; it functions as a precursor to azelate-based plasticizers (diesters) for imparting flexibility to polymers; and it is an industrial intermediate for azelate-derived esters and specialty azelate chemicals in chemical manufacture.
