product description
Ethylenediaminetetra-acetic acid (abbreviated as EDTA) is used in several industrial applications attributing to its high ability to bind to most of metal cations.  EDTA is produced as several salts, e.g. ethylenediaminetetra-acetic acid disodium salt (EDTAS). EDTA and its salts are used as chelating agents in cosmetic formulations.

Product Usage

DTA disodium salt, a versatile chelating agent, is widely utilized for its exceptional ability to sequester divalent metal ions, particularly calcium and magnesium. In the pharmaceutical and cosmetic industries, it is an essential stabilizer and preservative booster, preventing the oxidative degradation of active ingredients caused by trace metal impurities. Its primary application in food and beverage is to maintain color, flavor, and clarity by inhibiting enzyme-catalyzed oxidation. In laboratory settings, it is a standard reagent for complexometric titrations and biochemical assays. Furthermore, it is extensively used in industrial cleaning and water treatment to prevent scale formation and in the textile industry to ensure consistent dyeing by removing metal interference from processing water.
