Also used in the  dyeing adjuvant, processing agent for fibers, cosmetic additive, etc.

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.
