What is EDTA 4Na (Tetra Sodium EDTA)?

EDTA 4Na, or Tetrasodium Ethylenediaminetetraacetate, is the tetrasodium salt of EDTA. It appears as a white crystalline powder or granules and is highly soluble in water. EDTA 4Na functions as a chelating agent, meaning it binds to and inactivates metal ions such as calcium, magnesium, iron, and copper.

By sequestering these metal ions, EDTA 4Na prevents unwanted chemical reactions, such as oxidation or scale formation, making it essential in cleaning formulations, water treatment, personal care products, and industrial applications.

USES AND APPLICATIONS

INDUSTRIES

EDTA 4Na is widely used in:

• Water treatment (softens hard water, prevents scale)

• Detergents and cleaners (improves performance in hard water)

• Cosmetics and personal care products (stabilizes formulations)

• Textile and paper industry (bleaching and dyeing assistance)

• Photography (as a stabilizer in processing solutions)

• Laboratories and analytical chemistry (complexometric titrations)

KEY ADVANTAGES

• Strong chelating power for metal ions

• Enhances stability and shelf life of products

• Prevents scale, discoloration, and degradation

• Non-corrosive and environmentally safer than phosphate-based agents
