Ethylenediaminetetraacetic acid, widely abbreviated as EDTA, is an aminopolycarboxylic acid and a colourless, water-soluble solid. Its conjugate base is named ethylenediaminetetraacetate. It is widely used to dissolve limescale. 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+.

Disodium EDTA

Tetrasodium EDTA is a water-soluble ingredient used as a chelating agent in cosmetics and personal care products because of its ability to sequester metal ions and allow them to remain in formulas but lose their ability to react with other ingredients. This ability allows it to not only soften water, but preserve formulas as well by improving its stability when it is exposed to air and prevent microbial growth.


EDTA 4NA is a versatile sequestering agent, forming stable, water-soluble chelates with polyvalent metal ions in a wide ph range.


Used to eliminate enzyme inhibition by traces of heavy metals, and to inhibit enzymes that require divalent cations as cofactors. Iron-EDTA enhances damage due to reactive oxygen species, such as depletion of reduced glutathione, formation of methemoglobin, and lipid peroxidation


EDTA Mg is a stable water soluble metal chelate, mainly used in agriculture and horticulture as micronutrient, to prevent and correct Magnesium deficiencies. Applicable in Foliage fertilizers, in trickle irrigation, absorbed in NPK etc. EDTA Mg provides healthy growth to plant and maximum yield to crop


Pentetic acid or diethylene triamine pentaacetic acid (DTPA) is an aminopolycarboxylic acid consisting of a diethylenetriamine backbone with five carboxymethyl groups. The molecule can be viewed as an expanded version of EDTA and is used similarly. It is a white, water-soluble solid
