High-purity Vitamin C powder for pharmaceuticals, foods, and cosmetics.
Ascorbic Acid (Vitamin C) USP/FCC, Kosher 99% - 100.5%
Ascorbic Acid, commonly known as Vitamin C, is a high-purity compound (99% - 100.5%) with multiple applications in pharmaceuticals, food additives, and cosmetics. This potent antioxidant is vital for health and is used in the production of supplements, fortified foods, and skincare formulations. It appears as colorless crystals or white to nearly white powder, meeting rigorous BP/USP/EP/FCC/E300 standards. Its solubility in various alcohols like propylene glycol, glycerin, and isopropyl alcohol makes it versatile for different formulations. Ascorbic Acid offers excellent stability when stored in dry, light-protected, and cool conditions, but it is sensitive to moisture, heat, and oxidative materials. Certified kosher and available with a Certificate of Analysis (COA) for bulk orders, it is a reliable choice for commercial and industrial use. Lead, iron, and copper content are tightly controlled (≤10 ppm, ≤2 ppm, and ≤5 ppm, respectively) to ensure purity and safety. Perfect for pharmaceutical manufacturers, food industry professionals, skincare formulators, laboratories, and wholesale buyers.
