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 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.
Key Properties

- Industrial Cleaning: Acts as a builder in soaps and detergents to improve cleaning efficiency in hard water environments.
- Textile Processing: Utilized in bleaching and dyeing processes to prevent metal ion impurities from causing discoloration or fiber damage.
- Metal Finishing: Employed in electroplating and surface preparation to control metal ion concentrations in plating baths.
- Paper Manufacturing: Prevents brightness reversion by chelating metal ions during the bleaching process.
Safety & Handling
Trisodium EDTA should be handled by trained industrial professionals using appropriate Personal Protective Equipment (PPE), including safety glasses, gloves, and dust masks to prevent inhalation or contact. The product is a solid powder; avoid generating dust. Store in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly closed when not in use to prevent moisture absorption.
Refer to the Safety Data Sheet (SDS) for comprehensive safety, first aid, and disposal information.
