Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(4-Nonylphenyl)-.Omega.-(2-Sulfoethoxy)-, Sodium Salt is a high-performance, anionic surfactant belonging to the alkylphenol ethoxylate sulfonate class. This compound is engineered to deliver superior wetting, emulsification, and dispersion properties in demanding industrial formulations. It is a critical raw material for manufacturers in the agrochemical, textile, and industrial cleaning sectors who require robust and reliable performance under challenging conditions.

Application

• Agrochemical Formulations: Acts as a key wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates and wettable powders (WP).
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaners, and alkaline cleaning formulations for its excellent detergency and stability.
• Textile Processing: Serves as a scouring agent, dye leveling agent, and wetting agent in various textile pretreatment and dyeing processes.
• Emulsion Polymerization: Functions as an effective surfactant and stabilizer in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
• Oilfield Chemicals: Employed in drilling muds and production chemicals as an emulsifier and surfactant for enhanced oil recovery.
• Paint & Coating Additives: Used to improve pigment dispersion, wetting, and stability in water-based coating systems.
• Leather Processing: Aids in wetting and penetration during the tanning and dyeing stages of leather production.
