Usage:
Water Treatment & Chelating Agents: Binds metal ions in water, preventing scaling and eliminating the adverse effects of metal ions on industrial production.
Detergents & Cosmetics: Used as a stabilizer and water softener. Prevents discoloration, rancidity, and decreased foaming performance caused by metal ions.
Textile Industry: Eliminates heavy metal impurities and improves color fastness, brightness, and whiteness during fabric dyeing and bleaching.
Food & Pharma Grade: Used as an antioxidant synergist and preservative to prevent food oxidation and discoloration; used in pharmaceuticals as an anticoagulant and for heavy metal detoxification.
Agriculture: Used in the production of chelated micronutrient fertilizers (such as EDTA iron/zinc/manganese), significantly improving the efficiency of nutrient absorption by plants.
