Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(3-Carboxy-1-Oxo-3-Sulfopropyl)-.Omega.-(Nonylphenoxy)-, Disodium Salt is a high-performance, nonylphenol ethoxylate-based anionic surfactant and dispersant, distinguished by its unique carboxy-sulfopropyl functional group. This chemical structure provides exceptional stability, wetting power, and compatibility in demanding formulations, making it a critical component for achieving superior product performance. It is primarily utilized by manufacturers in the textile, paint and coatings, agrochemical, and industrial cleaning sectors where reliable dispersion and surface activity are paramount.

Application

• Textile Processing: Acts as a highly effective dispersing and leveling agent in dye baths, ensuring uniform color uptake and preventing dye agglomeration.
• Paints & Coatings: Serves as a pigment grinding aid and stabilizer, improving color development, gloss, and preventing settling in water-based and solvent-based systems.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticide and herbicide concentrates (ECs, SCs, WGs) to enhance stability and spray tank compatibility.
• Industrial & Institutional (I&I) Cleaners: Provides powerful wetting and soil suspension properties in heavy-duty alkaline and acidic cleaning formulations.
• Construction Chemicals: Functions as a plasticizer and water-reducing agent in cement admixtures to improve workability and final strength.
• Paper & Pulp Industry: Employed as a dispersant for pigments and fillers like calcium carbonate and kaolin in paper coating slips.
• Oilfield Chemicals: Utilized in drilling muds and completion fluids as a rheology modifier and dispersant for solids control.
