EDTA-4Na | Tetrasodium EDTA Chelating Agent
CAS: 64-02-8 | EC No.: 200-573-9
Product Overview
EDTA-4Na (Tetrasodium ethylenediaminetetraacetate) is a highly efficient chelating agent capable of forming stable complexes with a wide range of divalent and trivalent metal ions. It is particularly effective under alkaline conditions, providing excellent control of metal-induced reactions such as oxidation, discoloration, precipitation, and scale formation.
Widely used in detergents, personal care formulations, textile processing, water treatment, and industrial cleaning systems.
