Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-[3-[(Carboxymethyl)(2-Hydroxyethyl)Amino]-2-Hydroxypropyl]-.Omega.-(4-Nonylphenoxy)-, Monosodium Salt is a high-performance, nonionic surfactant and complexing agent belonging to the class of ethoxylated nonylphenol derivatives with a built-in iminodiacetic acid (IDA) functional group. This unique molecular structure provides exceptional chelating power for polyvalent metal ions combined with superior surface-active properties, making it a critical component in formulations requiring dual functionality. It is primarily utilized by industries where scale inhibition, detergency, and metal ion control are essential for process efficiency and product stability.

Application

• Industrial Cleaning & Detergents: Key ingredient in heavy-duty alkaline and acidic cleaners, degreasers, and metal cleaning formulations for its synergistic cleaning and sequestering action.
• Water Treatment Chemicals: Acts as a scale inhibitor and dispersant in cooling water, boiler water, and reverse osmosis systems, effectively controlling calcium, magnesium, and other metal salt deposits.
• Textile Processing: Used in scouring, bleaching, and dyeing baths to sequester metal ions that can interfere with chemical processes and cause fabric discoloration.
• Pulp & Paper Industry: Employed as a stabilizer in hydrogen peroxide bleaching and as a dispersant to prevent pitch and deposit formation.
• Enhanced Oil Recovery (EOR): Functions as a surfactant in chemical flooding formulations to reduce interfacial tension and improve oil displacement.
• Agrochemical Formulations: Serves as an emulsifier, dispersant, and compatibility agent in pesticide and herbicide concentrates.
• Personal Care & Cosmetics: Used in select rinse-off products as a foaming agent and chelant, though usage is regionally restricted due to the nonylphenol ethoxylate component.
• Metal Surface Treatment: Incorporated into pickling and plating baths to complex free metal ions and improve surface finish quality.
