Strong Chelating Ability – EDTA effectively binds to a wide range of metal cations, making it a powerful chelating agent.
Versatile Industrial Use – It is applied across various industries due to its metal-binding properties.
Multiple Salt Forms – Available in different salt forms such as disodium EDTA, offering flexibility in formulation.
Cosmetic Applications – Widely used as a chelating agent in cosmetic products to enhance stability and performance.
Ethylenediaminetetraacetic acid (EDTA) is widely used in various industrial applications due to its strong ability to bind with a broad range of metal cations. It is available in several salt forms, such as disodium EDTA (EDTAS). Both EDTA and its salts serve as effective chelating agents in cosmetic formulations.

Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid and a hexadentate ligand that forms octahedral complexes by chelating with metal ions, particularly cations. Its disodium salt form (EDTA) functions as a blood anticoagulant, playing a role in the development of pseudothrombocytopenia by binding calcium in the blood and preventing clotting. It is commonly used in hematological tests and also enhances the antibacterial activity of lysozyme.
