  • Applications

    Dipotassium EDTA dihydrate (CAS 25102-12-9) is widely used as a chelating agent to bind and sequester metal ions in a range of formulations. In detergents and cleaners, it softens water and stabilizes formulations by chelating metal ions; in water treatment it helps control scale and corrosion; in cosmetics and personal care it improves formulation stability and color retention through metal ion chelation; in polymers and plastics processing it acts as a stabilizer and processing aid by scavenging trace metals; in agriculture and hydroponics it is used to chelate micronutrients in fertilizers; in analytical chemistry it serves as a standard reagent for metal ion complexation and titration.
