Ethylenediaminetetraacetic Acid Tetrasodium Salt

Product introduction:

Ethylenediaminetetraacetic Acid Tetrasodium Salt (EDTA.4Na) is one of the most powerful and stable chelating agents in alkaline environments. It forms stable complexes with multivalent metal ions such as calcium (Ca2+), iron (Fe3+), copper (Cu2+), and magnesium (Mg2+), thereby reducing water hardness, preventing scale formation, and enhancing the stability of industrial formulations.

  • Chemical Name
  • Tetrasodium Ethylenediaminetetraacetate
  • Common Name
  • EDTA.4Na
  • Product Name
  • EDTA.4Na
  • Packaging
  • 25 kg Bag

Features & Benefits:

  • Chelating agent
  • Soluble in water
  • High stability in alkaline environments
  • Limited biodegradability

Applications:

  • Detergent, Cosmetics & Personal Care: Used as a chelating agent to stabilize formulations, improve foam performance and prevent the negative effects of metal ions in shampoos, detergents, and personal care products.
  • Textile & Dyeing Industry: Controls metal ions to prevent purity loss and color changes in synthetic dyes, while improving color uniformity and stability.
  • Agriculture: Used in fertilizers to supply micronutrients such as iron, zinc, manganese, and copper in bioavailable forms for plants (e.g., Zn-EDTA, Fe-EDTA).
  • Water & Wastewater Treatment: Used to control water hardness, prevent scaling and corrosion in water facilities, and remove heavy metals from industrial effluents. It also improves the stability of chlorine and disinfectants by controlling metal ions.
  • Pulp & Paper Industry: Used to control heavy metals and improve the pulp bleaching process.
