Description

n-(2-Hydroxyethyl)Ethylenediamine-N,N',N'-Triacetic Acid Trisodium Salt is a high-purity, water-soluble chelating agent and complexing compound. This versatile chemical is critical for processes requiring the effective sequestration of di- and trivalent metal ions in aqueous systems. It is essential for manufacturers and formulators in industries such as pharmaceuticals, personal care, industrial cleaning, and water treatment where precise metal ion control is paramount for product stability and performance.

Application

• Pharmaceutical Synthesis & Formulation: Acts as a stabilizing agent and metal chelator in injectable solutions, ophthalmic preparations, and other sensitive drug products to prevent catalytic degradation.
• Personal Care & Cosmetics: Used in shampoos, creams, and lotions as a sequestrant to enhance shelf-life by binding trace metals that can cause rancidity or color changes.
• Industrial Cleaning & Detergents: A key component in heavy-duty cleaning formulations, boiler descaling agents, and metal surface treatments to control water hardness and improve surfactant efficacy.
• Water Treatment Chemicals: Employed in cooling water systems and industrial process water to inhibit scale formation and corrosion by chelating calcium, magnesium, and iron ions.
• Analytical Chemistry & Laboratory Reagents: Serves as a standard or buffer component in complexometric titrations and various analytical methods for metal ion determination.
• Textile & Pulp Processing: Utilized in bleaching baths and dyeing processes to deactivate metal impurities that could affect fiber quality or color consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
