EDTA-2NA is a white crystal powder with two crystal water,
easy to lose crystal water when dried and easy to soluble in water,
but hard to soluble in organic solvents like alcohol or ethyl ether.
The PH value of 5%(25 °C ) aqueous solution is 4.0~6.0.
EDTA-2Na is used in detergent, liquid soap, shampoo, agricultural chemicals,fixer solution for development of color film, water cleaner, PH modifier.
Properties: white crystal powder soluble in water, and a variety of metal ion chelation.This product is used as bleaching fixing solution and dyeing aid, fiber treatment agent, coagulant,complexing agent, detergent, stabilizer, synthetic rubber, polymerization initiator of heavy metal quantitative analysis agent, etc., lies in the initiation system.
Disodium EDTA, as a component of active agent, is mainly used in cosmetics for complexing iron ions and controlling polymerization.The reaction speed, at the same time, can also be used for cleaning.
