Description

Trisodium N,n-Bis(Carboxymethyl)-3-Amino-2-Hydroxypropionate is a high-purity, water-soluble chelating agent and complexing salt, valued for its exceptional stability and sequestering power across a wide pH range. This compound is engineered to deliver superior performance in applications requiring the control of metal ions, preventing unwanted precipitation and catalysis. It is a critical raw material for formulators and manufacturers in the personal care, detergent, industrial cleaning, and water treatment industries, where consistent quality and reliable supply are paramount.

Application

• Personal Care Formulations: Acts as a highly effective chelating agent in shampoos, liquid soaps, and creams to sequester calcium and magnesium ions, enhancing surfactant performance and product stability.
• Detergent & Cleaning Products: Used in industrial and institutional cleaners, dishwashing liquids, and laundry detergents to prevent scale formation, improve cleaning efficiency, and protect equipment.
• Water Treatment Processes: Employed as a scale and corrosion inhibitor in boiler water, cooling water, and reverse osmosis systems to manage water hardness.
• Textile & Pulp Processing: Serves as a chelant in bleaching, dyeing, and finishing operations to control metal ions that can cause fabric degradation or color inconsistencies.
• Agricultural Formulations: Used in certain pesticide and fertilizer solutions to improve stability and compatibility by chelating trace metals.
• Industrial Process Chemistry: Functions as a stabilizing agent and metal ion control additive in various chemical synthesis and manufacturing processes.

Quality Control

Our Trisodium HEDTA is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, heavy metal content, loss on drying, and other critical parameters is available for each shipment 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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial opening to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
