Product Description
Ethylenediaminetetraacetic Acid Tetrasodium Salt EDTA-4Na
EDTA, is a good complexing agent in chemistry. It has six coordination atoms. The complex formed is called chelate. EDTA is often used in coordination titration It is generally to determine the content of metal ions. EDTA has important uses in dyes, food, medicine and other industries.
Ethylenediaminetetraacetic acid disodium is white crystalline particles or powder, odorless and tasteless. It is soluble in water and extremely insoluble in ethanol. It is an important chelating agent that can chelate metal ions in solution. Prevents discoloration, deterioration, turbidity caused by metals and oxidative loss of vitamin C, and also improves the oxidation resistance of fats and oils (the trace metals in fats and oils, such as iron and copper, can promote the oxidation of fats and oils)

Application
EDTA is mainly used for water treatment, as an additive to detergent, a chemical for photography, paper-making and oil-field. It is also used as detergent for boiler cleaning and reagent in chemical analysis.
1. High molecular chemical industry: EDTA is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre production.
2.Daily chemicals: EDTA is used as additive to detergent, skin cream and hair-conditioner.
3.Paper-making: EDTA is used for treating the steamed fibre. It will promote the whiteness of paper and reduce the incrustation in the steamer.
4.Pharmaceutical industry: Through cyclopolymerization with methyl amide, EDTA is made into ethyl amide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin.
5. Textile dyeing and printing: EDTA will promote colour ability of the dyestuff and brightness of the dyed fabric.
