Description

Trisodium 2-[Carboxylatomethyl-[2-(Carboxylatomethyl-(2-Hydroxyethyl)Amino)Ethyl]Amino]Acetate is a high-purity, water-soluble chelating agent and complexing salt. This compound is valued for its exceptional ability to sequester and deactivate di- and trivalent metal ions, preventing unwanted precipitation and catalytic degradation. It is essential for industries requiring precise control over metal ion activity in aqueous systems, such as personal care, industrial cleaning, and water treatment formulations.

Application

• Personal Care & Cosmetics: Acts as a highly effective chelating agent in shampoos, liquid soaps, and creams to stabilize formulations by inactivating trace metal ions that can cause rancidity and discoloration.
• Industrial & Institutional (I&I) Cleaning: Used in alkaline and acidic detergent formulations for hard surface cleaning, where it controls water hardness and enhances surfactant performance.
• Water Treatment: Employed as a scale and corrosion inhibitor in cooling water systems and boiler water treatment by complexing calcium, magnesium, and iron ions.
• Textile Processing: Serves as a chelant in dyeing and bleaching baths to prevent metal-ion interference, ensuring consistent color yield and fabric quality.
• Pulp & Paper Production: Used in bleaching sequences to deactivate transition metals, protecting cellulose fibers and improving the efficiency of bleaching agents like hydrogen peroxide.
• Agriculture: Incorporated into certain agrochemical formulations and micronutrient fertilizers to improve the stability and bioavailability of active ingredients.

Quality Control

Our Trisodium HEDTA is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metal content, and loss on drying are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent caking and degradation from atmospheric moisture.
