Trisodium EDTA

Product Overview

Trisodium EDTA (Ethylenediaminetetraacetic acid trisodium salt) is a high-purity chelating agent utilized extensively in industrial applications to sequester metal ions. By forming stable, water-soluble complexes with multivalent metal ions, this Technical Grade salt prevents precipitation and scale formation in process water and liquid formulations. It is supplied as a white crystalline powder with high solubility, ensuring rapid dispersion in aqueous solutions.

Engineers and formulators rely on Trisodium EDTA for its ability to improve the stability and efficacy of detergents, metal finishing baths, and water treatment systems. It is particularly effective in neutralizing the adverse effects of hard water ions (calcium and magnesium) and heavy metals (iron, copper, manganese), which can interfere with chemical reactions or degrade product shelf life. This product is manufactured to strict specifications (CAS 150-38-9) to ensure consistent performance across batches.
