What is Ethylenediaminetetraacetic Acid Disodium Salt?

Ethylenediaminetetraacetic Acid Disodium Salt is a widely used chelating agent and a disodium salt of ethylenediaminetetraacetic acid (EDTA). It effectively binds and deactivates di- and trivalent metal ions (such as Ca²⁺, Mg²⁺, Fe³⁺) in aqueous solutions. This property makes it invaluable across numerous industries, including water treatment, cosmetics, food, pharmaceuticals, and detergents, where it helps to prevent metal-ion catalyzed degradation, improve stability, and enhance product performance.
