  • Applications

    Edetate tripotassium (CAS 17572-97-3) is a versatile chelating agent used to sequester metal ions across many formulations in industry and consumer products. It is commonly employed in household and industrial cleaners to control metal ions, improving cleaning performance and formulation stability; in cosmetics and personal care to preserve formulations by binding trace metals; in industrial manufacturing and metal finishing to manage metal ion concentrations in plating and processing baths; in coatings, inks, and adhesives to enhance pigment dispersion and long-term stability; and in polymers and plastics to stabilize formulations and processing by inhibiting metal-catalyzed degradation; in agriculture as a chelating agent for micronutrient delivery in fertilizer systems.
