Disodium ethylenediaminetetraacetate (also known as disodium EDTA) is a powerful chelating agent. Due to its high stability constant and extensive coordination properties, it can almost interact with most metal ions except alkali metals ( Such as iron, copper, calcium, magnesium and other multivalent ions) chelate to form stable water-soluble complexes, eliminating metal ions or harmful reactions caused by them.

Disodium EDTA is a white crystalline powder that is soluble in water and almost insoluble in ethanol and ether. The pH value of its aqueous solution is about 5.3 and is used in detergents, dyeing auxiliaries, fiber processing agents, cosmetic additives, food additives, agricultural micro-fertilizers and Mariculture, etc.
