Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(Methylphenyl)-.Omega.-Hydroxy- is a nonionic surfactant belonging to the class of alkylphenol ethoxylates, specifically a methylphenyl-capped polyethylene glycol. This compound is valued for its excellent surface-active properties, acting as an effective emulsifier, wetting agent, and dispersant in a wide range of industrial formulations. It is a critical raw material for manufacturers in the agrochemical, coatings, textile, and industrial cleaning sectors who require reliable performance and consistent quality in their end products.

Application

• Agrochemical Formulations: Primary use as an emulsifier and dispersant in pesticide and herbicide concentrates (EC, SC formulations).
• Industrial & Institutional (I&I) Cleaners: Key surfactant in heavy-duty degreasers, metal cleaners, and floor care products.
• Coatings & Paints: Acts as a pigment wetting and grinding aid, improving dispersion stability in water-based and solvent-based systems.
• Textile Processing: Used in scouring, dyeing, and finishing operations as a wetting and leveling agent.
• Oilfield Chemicals: Component in drilling muds and production chemicals for emulsification and demulsification processes.
• Polymerization: Serves as a surfactant or stabilizer in emulsion polymerization processes for synthetic rubbers and plastics.
