Ethylene Diamiine Tetra Acetic Acid-Disodium (EDTA-2NA)

Properties:
EDTA-2NA is a white crystalline powder, containing two crystal water, dry easily lose crystal water, aqueous solution of the pH value of 4 - 5, insoluble in ethanol, ether and other organic solvents.

Feature:
EDTA-2Na salt is a white powder with two crystal waters, 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% (25degree) water solution is 4.0-6.0.

Use:
EDTA. 2Na is a good pincers mixture/ the complexing agent, is used to soften with hard water mainly, It can get various metal ion in effect chelation/ complexation hard water (to be that the calcium, magnesium, iron, lead, copper, manganese wait mainly). Be used for the detergent, dyeing help an agent, fibre sells the agent, cosmetics additive, food additives at reduced prices, agriculture tiny fertilizer and mariculture etc.

Storage:
Be stored on shelves in dry and ventilated warehouse. Avoid breakage of the bags, humidity and contamination
