EDTA disodium (Na2EDTA) is a salt form of ethylenediaminetetraacetic acid (EDTA), a chelating agent that can bind to metal ions and form stable complexes with them. EDTA disodium is a white, crystalline powder that is soluble in water and commonly used in various industries, including food, pharmaceuticals, and cosmetics.
EDTA disodium is used as a sequestrant and stabilizer in food and beverage products to prevent oxidation and other chemical reactions that can degrade the quality of the product. It is also used as a preservative in some personal care products to prevent bacterial growth.
