Description

Tetrakis(Bis(2-Hydroxyethyl)Ammonium) Ethylenediaminetetraacetate is a specialized, water-soluble chelating agent derived from ethylenediaminetetraacetic acid (EDTA). This compound matters for its enhanced solubility and sequestering power, making it highly effective in binding and deactivating di- and trivalent metal ions in aqueous systems. It is needed by formulators in industries such as personal care, agrochemicals, and industrial cleaning, where superior chelation performance in neutral to alkaline conditions is required to prevent metal-catalyzed degradation and improve product stability.

Application

• Personal Care & Cosmetics: Acts as a highly effective chelating agent in shampoos, creams, and lotions to sequester calcium and magnesium ions from hard water, enhancing surfactant performance and stabilizing formulations against rancidity.
• Agrochemical Formulations: Used in micronutrient fertilizers and pesticide formulations to chelate essential metal ions like iron, zinc, and manganese, improving their bioavailability and stability in solution.
• Industrial & Institutional (I&I) Cleaning: Serves as a key builder in detergent and cleaner formulations for hard surface cleaning, laundry, and dishwashing, preventing scale formation and improving cleaning efficacy.
• Textile Processing: Employed in dyeing and bleaching baths to complex with metal impurities in water and fabric, ensuring consistent color yield and preventing catalytic damage to textiles.
• Pulp & Paper Industry: Used in bleaching processes to deactivate transition metal ions (e.g., iron, copper) that catalyze the decomposition of bleaching agents like hydrogen peroxide, thereby improving process efficiency and pulp quality.
• Water Treatment: Functions as a scale and corrosion inhibitor in boiler and cooling water systems by sequestering calcium, magnesium, and other metal ions that cause deposits.
• Laboratory & Analytical Reagent: Utilized as a component in buffer solutions and analytical chemistry for complexometric titrations and metal ion masking.
• Pharmaceutical Intermediate: May be used in the synthesis of certain pharmaceutical compounds where a highly soluble EDTA derivative is required for metal ion control.

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). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can lead to caking or reduced efficacy.
