EDTA - Dissolvine Z

Ethylenediami­netetraacetic Acid

Technical grade

EDTA is a white odourless, colourless crystalline powder, with a melting point of 240C at which it decomposes. It is insoluble in cold water, alcohol and general organic solvents, slightly soluble in water, soluble in sodium hydroxide, sodium carbonate and ammonia solution, soluble in boiling water. The alkali metal salts are soluble in water. EDTA (Ethylene Diamine Tetraacetic Acid) is an important complexing agent. EDTA is widely used, can be used for processing colour photographic materials bleach fixing bath washing, dyeing auxiliaries, textile processing auxiliaries, detergent, stabiliser, synthetic rubber and polymerization initiator.

EDTA is predominatly used in agriculture, water treatment, pulp and paper industries and also used in the manufacture of cleaners and detergents.

Chelating agents bind or capture trace amounts of iron, copper, manganese, calcium and other metals that occur naturally in many materials. Such naturally occurring metals can cause chemical degradation, discoloration, scaling, instability, rancidity, ineffective cleaning performance and other problems.

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, bacteridal cleaners, vehicle washes etc.

Other key applications for EDTA 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. I Water treatment - to control water hardness and scale-forming calcium and magnesium ions and to prevent scale formation.
