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.
Packaging: 25kg white woven bag or drum lined with plastic bag; should be preserved to avoid sunlight, moisture and fire
