  • Applications

    Diammonium EDTA (CAS 20824-56-0) is primarily used as a chelating (sequestering) agent to bind metal ions and improve stability and performance across a range of industrial and consumer formulations. In detergents and household cleaners it helps prevent precipitation and enhances cleaning efficiency by binding metal ions; in cosmetics and personal care it stabilizes formulations against metal-catalyzed oxidation; in coatings and inks it improves pigment dispersion and color stability by sequestering trace metals; in polymers and plastics processing it acts as a processing stabilizer to reduce metal-catalyzed degradation; in agriculture it is used to form chelated micronutrient complexes for fertilizers or foliar sprays, increasing nutrient availability; and in paper, textiles, and water-treatment formulations it serves as a metal ion scavenger to reduce interference, corrosion, or scale formation.
