EDTA Disodium Salt DiHydrate

EDTA disodium salt, also known as ethylenediaminetetraacetic acid disodium salt, is a synthetic compound derived from ethylenediamine and chloroacetic acid. It belongs to the class of chelating agents, which can bind metal ions.

Chemical Formula: C10H14N2Na2O8

Appearance: A white, crystalline powder.

Uses:

• Food Additive: EDTA disodium salt is approved as a food additive in some countries and may be used to sequester metal ions that can catalyze oxidation reactions or degrade food quality. It helps maintain color, flavor, and nutritional value in processed foods and beverages.

• Cosmetics and Personal Care Industry: It helps enhance product stability, prevent color changes, and maintain product integrity during storage of certain cosmetic formulations.

• Analytical Chemistry: In laboratory analysis, it may be used for the quantitative determination of metal ions in samples such as water, soil, food, and biological fluids. It enables the selective extraction and measurement of specific metal ions of interest.

• Chelating Agent: EDTA disodium salt is primarily used as a chelating agent to sequester metal ions such as calcium, magnesium, iron, and copper. It forms stable complexes with these metal ions, preventing them from reacting with other compounds or causing unwanted interactions.

• Textile and Pulp Industries: Utilized in textile and pulp industries to chelate metal ions present in process water and chemicals. It helps prevent metal ion-induced discoloration, improve dyeing and bleaching processes, and enhance the quality of finished products.
