Disodium ethylen ediamine tetraacetic acid is a powerful chelating agent, preservative and antioxidant. Due to the high stability constant, with alkali metal outside most of the metal ions can generate stable complex compound, removing metal ions, or caused by the harmful effects of inhibition of boiled food water turbidity, prevent food oxidation discoloration, which works as an antioxidant, protecting color, anticorrosive, make the product quality is stable, is a very widely used stabilizer.color-protecting, quality improver, and antioxidants, Preservative and preservative.

copper plating, gold plating, lead tin alloy, steel electrochemical polishing and copper before silver plating solution, can also be replaced by EDTA-Na. Also used in detergents, liquid soap, shampoo, agricultural chemical sprays, color photosensitive materials rinsing processing bleaching fixing solution, water purifier, PH regulator, anticoagulant, etc. In the reduction initiation system used for the polymerization of styrene butadiene rubber, EDTA disodium, as a component of the active agent, is mainly used for complexing ferrous ions to control the polymerization reaction rate.
