  • Applications

    Ascorbate (CAS 299-36-5) is used across a range of industrial applications with roles as an antioxidant and stabilizer, notably in cosmetics and personal care to protect active ingredients and extend shelf life; in food and beverages, ascorbate salts serve as preservatives and a vitamin C source, helping to maintain quality and color; in polymer, coatings and inks manufacturing, ascorbate often acts as a reducing/oxidation-stabilizing agent to mitigate degradation during processing and use; in cleaning and metal pretreatment formulations, ascorbate salts can function as chelating/reducing agents to complex metal ions and aid rust removal; in water treatment and plastics systems, ascorbate may be used as an additive to control oxidation; and in agriculture, it may be used as a vitamin C source for crops or in foliar sprays to help mitigate plant stress.
