Description

N,n-Bis(Carboxylatomethyl)Alanine Trisodium Salt is a high-purity, water-soluble chelating agent and complexing salt. This compound is valued for its strong metal-binding capabilities, particularly for calcium and transition metals, making it a critical component in formulations requiring sequestration and stabilization. It is primarily utilized by manufacturers in the detergent, personal care, and industrial cleaning sectors, as well as in specialized chemical synthesis and water treatment applications.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to inactivate water hardness ions, enhancing surfactant performance.
• Personal Care Products: Used in shampoos, liquid soaps, and other cosmetics as a chelating agent to stabilize formulations and improve shelf life.
• Industrial Cleaning & Descaling: Key ingredient in acidic or alkaline cleaners for boilers, heat exchangers, and membranes to prevent and remove mineral scale.
• Water Treatment: Employed in processes to control scale formation and inhibit corrosion in industrial water systems.
• Chemical Synthesis & Intermediates: Serves as a versatile building block or catalyst ligand in organic and coordination chemistry.
• Textile & Pulp Processing: Assists in bleaching and dyeing processes by chelating metal impurities that can affect product quality.
• Agricultural Formulations: Used in certain agrochemicals to improve stability and compatibility of micronutrients.
