Wholesale Chelating Agent EDTA 4Na CAS 67401-50-7

Destribtion:

Chelating Agent Tetrasodium EDTA is the salt resulting from the neutralization of ethylenediaminetetraacetic acid with four equivalents of sodium hydroxide (or an equivalent sodium base). It is a white solid that is highly soluble in water. Commercial samples are often hydrated, e.g. Na4EDTA.4H2O. The properties of solutions produced from the anhydrous and hydrated forms are the same, provided they are at the same pH.

Specification:

Application:

EDTA 4Na is incorporated in personal care products to chelate and sequester metal ions, in an effort to increase shelf life and enhance the products foaming properties. EDTA is used in shampoo, dyes, lotion, gel, cosmetics. EDTA 4Na has a pH higher than 7.

As an agent for complexation, 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.
