Description

Ethylenediaminetetraacetic Acid Trisodium Salt Trihydrate is a high-purity, water-soluble chelating agent widely used in industrial and laboratory applications. Its primary value lies in its exceptional ability to sequester di- and trivalent metal ions, preventing unwanted precipitation and catalytic activity. This makes it an essential component for manufacturers and researchers in sectors requiring precise metal ion control, such as pharmaceuticals, cosmetics, and analytical chemistry.

Application

• Pharmaceutical Manufacturing: Used as a stabilizing agent in formulations to chelate trace metals that can catalyze drug degradation, extending shelf-life.
• Cosmetics & Personal Care: Acts as a sequestrant in creams, lotions, and shampoos to improve product stability and clarity by binding water hardness ions.
• Laboratory Analysis: Serves as a key component in buffer solutions for complexometric titrations and as a metal deactivator in various analytical procedures.
• Industrial Cleaning & Descaling: Incorporated into cleaning formulations to dissolve and prevent scale deposits (e.g., calcium carbonate) in boilers and heat exchangers.
• Textile Processing: Used to control metal ions in dye baths, improving color fastness and consistency of the final product.
• Agriculture & Horticulture: Employed in micronutrient fertilizer solutions to keep metal ions in a bioavailable, soluble form for plant uptake.

Quality Control

Our Ethylenediaminetetraacetic Acid Trisodium Salt Trihydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for demanding industrial and laboratory applications. A comprehensive Certificate of Analysis (COA), detailing parameters such as assay, purity, and heavy metal content, is provided with every shipment to guarantee traceability and consistent quality.

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 product is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
