Description

α-Sulfo-ω-(Undecyloxy)Poly(Oxy-1,2-Ethanediyl), Sodium Salt, Branched And Linear is a high-performance anionic-nonionic hybrid surfactant, specifically a sulfated alcohol ethoxylate. This compound is engineered to deliver superior wetting, emulsifying, and dispersing properties in challenging formulations. It is a critical raw material for industrial manufacturers requiring robust and stable surface-active performance under a range of conditions.

Application

• Primary surfactant and emulsifier in industrial and institutional (I&I) cleaning formulations, including hard surface cleaners and degreasers.
• Key component in textile processing auxiliaries for scouring, dyeing, and finishing operations.
• Stabilizing and wetting agent in agricultural chemical formulations such as herbicides and pesticides.
• Emulsifier for metalworking fluids and lubricants, providing stability in oil-in-water systems.
• Dispersant and grinding aid in pigment and coating preparations.
• Foam control and detergent builder in pulp and paper processing chemicals.
• Raw material for synthesizing specialized surfactant intermediates with tailored properties.
