EDTA-4NA CAS 13235-36-4

What is EDTA 4NA CAS 13235-36-4?

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.
