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.

1.Water Treatment: Used as a scale and corrosion inhibitor in boiler water, cooling water, and industrial cleaning systems.
2.Cosmetics & Personal Care: Acts as a stabilizer in creams, lotions, and shampoos to prevent rancidity and discoloration caused by metal ions.
3.Food Industry: Approved as a preservative and color retention agent (INS 386) in beverages, canned goods, and sauces.
4.Pharmaceuticals: Serves as an anticoagulant in blood collection tubes and a chelator in drug formulations.
5.Detergents & Cleaners: Enhances cleaning efficiency by softening hard water and inactivating metal ions in stain removal.
6.Textile & Pulp Industry: Used in dyeing processes and as a stabilizer in hydrogen peroxide bleaching.
7.Laboratory Reagent: Commonly used in analytical chemistry and molecular biology for buffer preparation and metal ion control.
Ethylenediaminetetraacetic Acid Disodium Salt is generally considered safe for use in regulated applications. It is non-toxic at recommended levels but can cause irritation upon contact with eyes or skin. Prolonged exposure or ingestion of large amounts should be avoided. It is biodegradable under certain conditions.
