Disodium dihydrate (Disodium Ethylenediaminetetraacetate 2h2o) ethylenediamine tetraacetic acid, its properties are different. In terms of its properties, it is a white crystalline powder, easily soluble in water, but difficult to dissolve in organic solvents. This substance has good chelating properties and can form stable complexes with a variety of metal ions.

In terms of its application, it is often used as a chelating agent in the chemical industry. In the electroplating process, it can stabilize the plating solution and make the coating uniform and dense. In the food industry, it is used as a preservative and antioxidant. By chelating metal ions, it delays the oxidation and deterioration of food and ensures its quality and shelf life. In the field of medicine, it is also useful. For example, in pharmaceutical preparations, it can prevent the catalytic degradation of metal ions on drugs and ensure the stability of drugs.

As for the use, in water treatment, it can remove metal ions in water, prevent scaling and corrosion; in cosmetic formulations, it can chelate metals in water, protect the texture and efficacy of products, and prevent deterioration. Due to its unique properties and wide application, EDTA disodium dihydrate plays an important role in many industries, contributing greatly to production and life.
