EDTA (Ethylenediaminetetraacetic Acid)
Ethylenediaminetetraacetic acid (EDTA) was developed by Franz Munz inGermanyduring the 1930s as an alternative to citric acid. About the same time, Frederick Bersworth synthesized EDTA in the United States using a different technique. He obtained aUSpatent for this technique in1945. EDTAwas approvedby the US Food and Drug Administration (FDA) as a food additive in 1947. Since the early 1950s, E...

Ethylenediaminetetraacetic acid (EDTA) is a chelating agent can bind to metals via four carboxylate and two amine groups. It is a polyamino carboxylic acid and a colorless, water-soluble solid, which is widely used to dissolve lime scale. It is produced as several salts, notably disodium EDTA and calcium disodium EDTA. EDTA reacts with the calcium ions in dentine and forms soluble calcium chela...
