EDTA disodium salt GRG

Ethylenediami­netetraacetic acid disodium salt

Technical grade

Disodium EDTA occurs as white, odourless crystalline granules or a white to nearly white powder. It is freely soluble in water but insoluble in alcohol. It is used as sequestrant, chelating agent, stabiliser, antioxidant synergist and preservative. Chelating agents bind or capture trace amounts of iron, copper, manganese, calcium and other metals that occur naturally in many materials.

Uses for EDTA disodium salt:

  • In the detergent industry as a stabilizer.
  • In the chemical industry as a metal carrier in redox systems.
  • In the printing industry to control hardness and as a stabilizer.

Other applications include: Agricultural Formulations, Bleaching (Pulp), Electronics/Se­miconductors, Electroplating, Photography, Textile Processing, Water Softening.

In Metalworking indutries it is used for surface preparation, metal cleaning, metal plating, and in metalworking fluids.

In Cleaning products EDTA is employed to remove hard water scale, soap film, and inorganic scales. It is commonly used in a wide variety of cleaning products and formulations, including hard surface cleaners, laundry detergents, bactericdal cleaners, vehicle washes etc.

Other key applications for EDTA Disodium include: In Photography as a bleach in photographic film processing. In the manufacturing of paper to maximize bleaching efficiency during pulping, prevent brightness reversion, and protect bleach potency. In Scale removal and prevention - to clean calcium and other types of scale from boilers, evaporators, heat exchangers, filter cloths, and glass-lined kettles. Water treatment - to control water hardness and scale-forming calcium and magnesium ions and to prevent scale formation.

It is used in RO membrane cleaning.
