Synonym: TETRASODIUM ETHYLENEDIAMINETETRAACETATE TETRAHYDRATE; ETHYLENEDIAMINETETRAACETIC ACID TETRASODIUM SALT TETRAHYDRATE; tetrasodium edta tetrahydrate; Ethylenediaminetetraacetic acid tetrasodium salt; edta tetrasodium salt
EDTA-4NA (CAS 13235-36-4), also known as tetrasodium EDTA tetrahydrate or ethylenediaminetetraacetic acid tetrasodium salt, is a widely used chelating agent with excellent ability to bind metal ions. It forms stable, water-soluble complexes with calcium, magnesium, iron, and other metal ions, making it essential in many industrial, cosmetic, and cleaning applications.
With its strong sequestering capability, EDTA tetrasodium salt helps improve the stability, clarity, and performance of formulations by preventing unwanted metal ion reactions.
