EDTA

|---|---|---|
Ethylenediaminetetraacetic acid (EDTA) is a medication used in the management and treatment of heavy metal toxicity. In foods, EDTA bound to iron is used to “fortify” grain-based products such as breakfast cereals and cereal bars. EDTA is also used in calcium and sodium compounds to preserve food; and to promote the color, texture, and flavor of food. In manufacturing, EDTA is used in calcium and sodium compounds to improve stability in pharmaceutical products, detergents, liquid soaps, shampoos, agricultural chemical sprays, oil emulsion devices, contact lens cleaners and cosmetics. It is also used in certain blood collection tubes used by medical laboratories |
Description | ||
|---|---|---|
Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-insoluble solid is widely used to bind to iron (Fe2+/Fe3+) and calcium ions (Ca2+), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca-containing scale as well as to deliver iron ions under conditions where its oxides are insoluble. EDTA is available as several salts, notably disodium EDTA, sodium calcium edetate, and tetrasodium EDTA, but these all function similarly. |
