We offer superior quality EDTA, disodium salt. It is a white
crystalline compound, which acts as a chelating agent and used in a
variety of industrial applications. Ethylenediaminetetraacetic acid,
widely abbreviated as EDTA is a polyamino carboxylic acid and a
colourless, water-soluble solid. Its conjugate base is named
ethylenediaminetetraacetate. It is widely used to dissolve scale.
Its usefulness arises because of its role as a hexadentate ("six-toothed")ligand
and chelating agent, i.e. its ability to "sequester" metal ions such
as Ca2+ and Fe3+. After being bound by EDTA, metal ions remain in
solution but exhibit diminished reactivity. EDTA is produced as
several salts, notably disodium EDTA and calcium disodium EDTA.
In industry, EDTA is mainly used to sequester metal ions in
aqueous solution. In the textile industry, it prevents metal ion
impurities from modifying colours of dyed products. 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." In similar manner, EDTA
is added to some food as a preservative or stabilizer to prevent
catalytic oxidative decolouration, which is catalyzed by metal ions.
In personal care products, it is added to cosmetics to improve their
stability toward air. In soft drinks containing ascorbic acid and
sodium benzonate, EDTA mitigates formation of benzene (a
carcinogen).
Disodium EDTA is a derivative of Ethylenediamine Tetraacetic Acid.
Ethylenediamine Tetraacetic Acid is a Sequestering /
Chelating Agent. EDTA is a synthetic amino acid. It is widely known
as EDTA. It is a white powder. EDTA Acid is insoluble in water. It
is also named as Ethylenediamine Tetraacetate. It is widely used to
dissolve Metallic Impurities. There are various Salts / Derivatives
of EDTA.
The stability of this bond is vital to get the success in
removing the inorganic impurities out of the system. If the bond is
weak, other chemicals can break this bond to form their own
compounds.

Disodium EDTA is a Sequestering Agent, which is used in various
Industries such as Pharmaceutical, Photography, Textile, Boiler
Turbine scale removal, Agriculture. It is used for removing unwanted
inorganic impurities present in the system, which helps in getting
superior performance & cost saving.
