ETDA Edetic Acid

ETDA Edetic Acid is the acid form of edetate, a chelating agent with anti-hypercalcemic and anticoagulant properties. Edetic acid binds calcium and heavy metal ions, forming soluble stable complexes which are readily excreted by the kidneys. This results in a decrease in serum calcium levels. This agent is also used as an anticoagulant for blood specimens and is applied as a treatment of lead poisoning.

Edetic acid is a Lead Chelator and Anti-coagulant. The mechanism of action of edetic acid is as a Lead Chelating Activity and Calcium Chelating Activity. The physiologic effect of edetic acid is by means of Decreased Coagulation Factor Activity.

Ethylenediamine tetraacetic acid is a colorless crystalline solid. It is slightly soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used in chemical analysis, to make detergents and cleaning compounds, and for many other uses.

Ethylenediaminetetraacetic acid (EDTA) is mainly used to bind metal ions in aqueous solution making EDTA useful in a wide variety of uses as a chelating agent. It is widely used to dissolve limescale. In shampoos, cleaners, and other personal care products EDTA salts are used as stabilizers. EDTA is added to some food as a preservative or stabilizer to prevent catalytic oxidative decoloration, which is catalyzed by metal ions. In the pulp and paper industry, EDTA inhibits the ability of metal ions, especially Mn2+, from catalyzing the disproportionation of hydrogen peroxide, which is used in "chlorine-free bleaching."
