Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Sulfo-.Omega.-(1,1,3,3-Tetramethylbutyl)Phenoxy-, Sodium Salt is a high-performance, nonionic-anionic surfactant belonging to the alkylphenol ethoxylate sulfonate class. This compound is valued for its excellent wetting, emulsifying, and dispersing properties, offering superior stability across a wide pH range. It is a critical raw material for formulators in the industrial cleaning, agrochemical, textile, and coatings industries who require robust and versatile surface-active agents.

Application

• Industrial & Institutional (I&I) Cleaners: A key component in heavy-duty degreasers, alkaline cleaners, and floor care formulations for its powerful emulsification of oils and fats.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticide and herbicide concentrates (EC, SC, EW formulations) to enhance stability and spray performance.
• Textile Processing: Employed as a wetting agent and detergent in scouring, dyeing, and finishing baths to ensure uniform penetration and processing.
• Coatings & Paints: Acts as a pigment dispersant and grinding aid in water-based systems, improving color development and preventing settling.
• Metal Working Fluids: Functions as an emulsifier in soluble oils and semi-synthetic coolants, providing lubrication and rust prevention.
• Enhanced Oil Recovery (EOR): Investigated for use in chemical flooding formulations to reduce interfacial tension and improve oil displacement.
