Description

Tetraammonium Ethylenediaminetetraacetate is the tetraammonium salt form of the widely used chelating agent EDTA. This compound is valued for its superior solubility in aqueous systems and its powerful ability to sequester di- and trivalent metal ions, preventing unwanted precipitation and catalytic activity. It is essential for industries requiring high-purity, water-soluble chelation in formulations, including detergents, textile processing, personal care products, and water treatment.

Application

• Detergent & Cleaning Formulations: Acts as a water softener and builder, enhancing surfactant efficiency by chelating calcium and magnesium ions that cause hardness.
• Textile Processing: Used in dyeing and bleaching baths to complex metal impurities that can cause color distortion or fabric degradation.
• Personal Care & Cosmetics: Serves as a stabilizer and chelating agent in shampoos, liquid soaps, and creams to improve shelf life and product clarity.
• Industrial Water Treatment: Prevents scale formation in boilers and cooling systems by sequestering scale-forming cations.
• Pulp & Paper Industry: Chelates metal ions during bleaching processes to protect cellulose fibers and improve brightness.
• Agriculture: Can be used in micronutrient fertilizers and as a chelating agent in agrochemical formulations.
• Laboratory & Analytical Reagent: Employed in analytical chemistry and buffer solutions for complexometric titrations.

Quality Control

Our Tetraammonium EDTA is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters are available for every 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation from atmospheric moisture.
