Description

Glycine, N-(Carboxymethyl)-N-2-(Carboxymethyl)Aminoethyl-, Trisodium Salt is a high-purity, water-soluble chelating agent and complexing salt, known commercially as Trisodium Nitrilotriacetate (NTA). This compound is valued for its exceptional ability to sequester and deactivate di- and trivalent metal ions, preventing precipitation and scaling in aqueous systems. It is a critical raw material for industrial formulators and manufacturers in sectors requiring controlled metal ion activity, such as detergents, water treatment, and textile processing.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance surfactant efficiency and prevent soap scum in laundry and dishwashing products.
• Industrial Water Treatment: Used for boiler and cooling water treatment to control scale formation by chelating calcium, magnesium, and other metal ions.
• Textile Processing: Serves as a chelating agent in dyeing and bleaching baths to improve color fastness and process consistency by controlling water hardness.
• Pulp & Paper Manufacturing: Enhances bleaching efficiency and stabilizes hydrogen peroxide by chelating transition metal catalysts.
• Agricultural Chemicals: Used in micronutrient fertilizers and pesticide formulations to improve stability and bioavailability of metal ions.
• Personal Care Products: Incorporated as a stabilizer and chelant in formulations like shampoos and liquid soaps.
• Metal Plating & Surface Treatment: Functions in electroplating baths to complex metal ions, ensuring smooth and even deposition.
• Laboratory & Analytical Reagent: Employed in analytical chemistry as a standard or buffer component for complexometric titrations.
