Features of EDTA-2NA:
Ethylene diamine tetraacetic 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:
1.High molecular chemical industry: EDTA Disodium Salt is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre production.
2.Daily chemicals: EDTA Disodium Salt is used as additive to detergent, skin cream and hair-conditioner.
3.Paper-making: EDTA Disodium Salt 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 Disodium Salt 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 Disodium Salt will promote colour ability of the dyestuff and brightness of the dyed fabric
