Disodium Ethylenediaminetetraacetic acid is a white or milky white crystal or granular powder that is tasteless, odorless or slightly salty. It is soluble in water but extremely difficult to dissolve in ethanol. It is an important chelating agent that can chelate metal ions in solution. Preventing metal induced discoloration, deterioration, turbidity, and oxidation loss of vitamin C can also improve the antioxidant properties of oils.

Among the salts of ethylenediaminetetraacetic acid, the disodium salt is the most important. It is an important complexing agent.It can also be used in electroless copper plating, gold plating, lead-tin alloy plating, electrochemical polishing of steel parts and solutions before silver plating of copper. It can also be replaced by EDTA-Na. Also used in detergents, liquid soaps,shampoos, agrochemical sprays, color sensitive materials, bleaching fixers, water purifiers, pH adjusters, anticoagulants, etc. In the reduction initiation system for the polymerization of styrene-butadiene rubber, disodium EDTA is used as a component of the active agent, and is mainly used for complexing ferrous ions to control the polymerization rate.
