What is EDTA 2Na (Disodium EDTA)?

EDTA 2Na, or Disodium Ethylenediaminetetraacetate, is the disodium salt of EDTA, a widely used chelating agent. It appears as a white, crystalline powder that is highly soluble in water. Its primary function is to bind metal ions, such as calcium, magnesium, iron, and lead, thereby deactivating their reactivity in various chemical and industrial processes.

Disodium EDTA is known for its ability to sequester metal ions, which helps improve product stability, enhance cleaning performance, and prevent discoloration or degradation due to metal contamination.

It is extensively used in cosmetics, pharmaceuticals, water treatment, laboratories, textile processing, and cleaning agents.

USES AND APPLICATIONS

INDUSTRIES

EDTA 2Na is commonly used in:

• Cosmetics and personal care products (as a stabilizer to prevent metal-catalyzed degradation)

• Pharmaceuticals (as a preservative and stabilizer)

• Water treatment (removal of hardness ions like calcium and magnesium)

• Cleaning agents and detergents (enhances effectiveness in hard water)

• Textile and paper industry (as a bleaching stabilizer and water softener)

• Laboratory reagents (for metal ion analysis and titration)

KEY ADVANTAGES

• Excellent chelating ability for a wide range of metal ions

• Enhances product shelf life and stability

• Improves cleaning performance in hard water

• Non-toxic and environmentally safer compared to phosphates
