Description

n-(2-Hydroxyethyl)Ethylenediaminetriacetic Acid, Trisodium Salt Hydrate, 85 is a high-purity, water-soluble chelating agent belonging to the aminopolycarboxylate family. This compound is valued for its superior sequestering power for di- and trivalent metal ions, particularly under alkaline conditions, making it a critical component in formulations requiring stable metal complexation. It is essential for industrial and laboratory professionals in sectors such as detergent manufacturing, water treatment, textile processing, and as a stabilizing agent in various chemical syntheses.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), enhancing surfactant efficiency and preventing scale deposition.
• Industrial Water Treatment: Used in boiler and cooling water systems to control scale and corrosion by chelating metal ions like iron and copper.
• Textile Processing: Serves as a chelating agent in dyeing and bleaching baths to prevent metal-ion interference, ensuring consistent color quality and fabric strength.
• Pulp & Paper Industry: Improves bleaching efficiency and brightness of pulp by sequestering transition metals that catalyze peroxide decomposition.
• Chemical Synthesis & Catalysis: Functions as a ligand or stabilizer in various catalytic processes and as a buffer in complexometric titrations.
• Personal Care Products: Incorporated into formulations like shampoos and liquid soaps as a stabilizer and to improve clarity by binding trace metals.
• Agriculture: Used in micronutrient fertilizers and agrochemical formulations to enhance the bioavailability and stability of metal ions.
• Laboratory Research: Employed as an analytical reagent for complexometric titrations and in buffer solutions for biochemical studies.

Quality Control

Our n-(2-Hydroxyethyl)Ethylenediaminetriacetic Acid, Trisodium Salt Hydrate, 85 is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profile, and physical parameters is provided with each shipment to guarantee traceability and compliance with your quality requirements.

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 sealed immediately after use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
