  • Applications

    edetate dipotassium anhydrous (CAS 2001-94-7) is a chelating (sequestering) agent used to bind metal ions and stabilize formulations, helping to prevent metal-catalyzed oxidation and color changes. Real-world applications include as a chelating agent in detergents and household cleaners; as a stabilizer and cosmetic additive in cosmetics and personal care products; as a chelating/stabilizing agent in pharmaceutical solutions; as a sequestrant in food processing to control metals and stabilize colors and flavors; and in industrial manufacturing and water treatment to reduce water hardness and improve process stability in activities such as plating, coatings, and inks.
