Product Description
Ethylenediaminetetraacetic Acid Disodium Salt#139-33-3
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.

Product Usage
Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid and a hexadentate ligand. It chelates with metal ions, especially with cations to form an octahedral complex. Ethylenediaminetetraacetic acid disodium salt (EDTA) is a blood anticoagulant and contributes to the pathogenesis of pseudothrombocytopenia. It chelates with calcium in the blood and inhibits clotting and is routinely used in haematological tests. It enhances the antibacterial activity of lysozyme.
