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. EDTAS is a preservative, sequestrant, and stabilizer in foods. EDTA is added to ascorbic acid-disodium benzoate containing soft drinks to mitigate the formation of benzene. EDTA and its salts are used as a component in the production of food-contact paper and paperboard. EDTAS is permitted in the feed and drinking water of animals and/or for the treatment of food-producing animals. In the textile industry, EDTA and its salts prevent metal ion impurities from changing colors of dyed products. In the pulp and paper industry, EDTA and its salts inhibit the ability of metal ions from catalyzing the disproportionation of hydrogen peroxide (a typical bleaching agent). EDTAS is used in synthetic rubber manufacture. EDTAS is also used as a corrosion inhibitor to carbon steel in the industries. As an anticoagulant, EDTAS and tripotassium salts of EDTA are most commonly used.
