Description

Ethylenediaminetetraacetic Acid Tetrasodium Salt is a highly effective, water-soluble chelating agent widely used to sequester di- and trivalent metal ions. Its core value proposition lies in its superior stability and solubility in aqueous systems compared to the free acid form, making it indispensable for controlling metal-catalyzed degradation and precipitation. This product is essential for manufacturers in the detergent, textile, pulp & paper, and personal care industries who require reliable metal ion control to ensure product stability, performance, and quality.

Application

• Detergent & Cleaning Formulations: Acts as a water softener and builder to enhance surfactant efficiency by chelating calcium and magnesium ions in hard water.
• Textile Processing: Used in dyeing and bleaching baths to prevent metal ion interference, ensuring consistent color and fabric quality.
• Pulp & Paper Industry: Stabilizes hydrogen peroxide and other bleaching agents by deactivating trace metals that catalyze decomposition.
• Personal Care & Cosmetics: Serves as a preservative booster and stabilizer in shampoos, liquid soaps, and creams by chelating metals that promote rancidity.
• Industrial Cleaning & Boiler Treatment: Prevents scale formation and aids in the removal of metal oxide deposits in cooling and boiler water systems.
• Agriculture: Used in micronutrient fertilizers and as a chelating agent in agricultural chemical formulations to improve nutrient availability.
• Laboratory & Analytical Chemistry: Employed as a standard reagent in complexometric titrations and buffer solutions.

Quality Control

Our Ethylenediaminetetraacetic Acid Tetrasodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for assay, purity, and physical parameters. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key quality attributes. While we offer technical and commercial grades, our processes are designed to support compliance with relevant industry standards for various applications.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area. Recommended storage temperature is 15-25°C. Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and CO2.
