Description

N,N'-Ethylenebis[n-(Carboxymethyl)Glycine], Compound With 2,2',2''-Nitrilotri(Ethanol) is a high-purity, complexing agent and chelator derived from ethylenediaminetetraacetic acid (EDTA) and triethanolamine. This compound is valued for its exceptional ability to sequester and deactivate metal ions, which is critical for stabilizing formulations and preventing unwanted catalytic degradation. It is primarily utilized by manufacturers in the personal care, industrial cleaning, and water treatment sectors where reliable metal ion control is essential for product performance and shelf life.

Application

• Personal Care & Cosmetics: Acts as a highly effective chelating agent in shampoos, creams, and lotions to bind metal ions that can cause rancidity and destabilize emulsions, thereby extending product shelf life.
• Industrial & Institutional (I&I) Cleaning: Enhances the performance of detergents, degreasers, and hard surface cleaners by sequestering water hardness ions (Ca2+, Mg2+) and heavy metals, improving surfactant efficiency and preventing scale formation.
• Water Treatment: Used in boiler and cooling water systems to control scale and corrosion by chelating metal ions that contribute to fouling and deposit formation.
• Chemical Synthesis & Process Industries: Serves as a stabilizing agent and metal scavenger in various chemical manufacturing processes to protect sensitive intermediates and final products from metal-catalyzed reactions.
• Textile & Leather Processing: Assists in dyeing and finishing processes by chelating metal ions in process water, which helps achieve consistent color and improves the quality of the final textile or leather product.
• Agriculture & Agrochemicals: Can be incorporated into certain pesticide and fertilizer formulations to improve stability and compatibility by mitigating the effects of trace metal contaminants.
