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.
Edetate Disodium is the disodium salt form of edetate, a heavy metal chelating agent with anti-hypercalcemic and anti-arrhythmic properties. Edetate, a heavy metal antagonist, chelates divalent and trivalent metals, forming soluble stable complexes which are readily excreted by the kidneys, thereby can be used to lower serum calcium concentrations. In addition, this agent exerts a negative inotropic effect on the heart through a transiently induced hypocalcemic state, thereby antagonizing the inotropic and chronotropic effects of digitalis glycosides on the ventricles of the heart. Upon ocular administration, edetate exerts its ophthalmic effect by chelating calcium to form soluble complexes, thereby removing corneal calcium deposits.
Applications of Na2 EDTA
Na2 EDTA (ethylenediaminetetracetic acid disodium) is a chelating agent, used to sequester and decrease the reactivity of metal ions that may be present in many industrial and personal care products.
EDTA Na2 is used in cleaners, detergent, fertilizers, fixer solution for development of colour film, water cleaner and pH modifier. It is also used in redox reaction for the polymerization of butyl benzene rubber, it is used as part of activator for the control of polymerization speed.
EDTA Na2 is used in Cosmetics to increase effectiveness and improve stability of bar and solid soaps, bath preparations; creams, oils, hair care products and many other personal care formulations.
Disodium Edta E386 can be used in food such as in Processed fruits and vegetables, Meat, Seafood, Egg and Dairy Products, Grain-Based Products.
