Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(Carboxymethyl)-.Omega.-(Diisononylphenoxy)-, Sodium Salt is a high-performance, nonionic surfactant and emulsifier belonging to the class of alkylphenol ethoxylate carboxylates. This specialty chemical is engineered to provide superior wetting, dispersing, and emulsification properties in demanding industrial formulations. It is a critical component for manufacturers in the agrochemical, coatings, textile, and industrial cleaning sectors seeking stable and effective surfactant systems.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates (EC, SC, EW formulations) to ensure stability and enhance biological efficacy.
• Industrial & Institutional (I&I) Cleaners: Provides excellent wetting and soil suspension in heavy-duty alkaline and acidic cleaning products for hard surface and metal cleaning.
• Coatings & Paints: Used as a pigment dispersant and grinding aid in water-based and solvent-based coating systems to improve color development and prevent settling.
• Textile Processing: Functions as a scouring agent, dye leveler, and wetting agent in various textile pretreatment and dyeing processes.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic metalworking fluids and rolling oils.
• Oilfield Chemicals: Employed in drilling muds and stimulation fluids as an emulsifier and surfactant for enhanced oil recovery (EOR) applications.
• Adhesives & Sealants: Aids in the emulsification and stabilization of polymer dispersions used in adhesive formulations.
