Description

9-Octadecene-1-Sulfonic Acid, Potassium Salt is an anionic surfactant and emulsifying agent derived from olefin sulfonation. This compound is valued for its excellent wetting, dispersing, and foaming properties in aqueous systems. It is primarily utilized in the formulation of industrial and institutional cleaning products, as well as in emulsion polymerization processes.

Application

• Primary emulsifier and surfactant in industrial and institutional (I&I) cleaning formulations.
• Stabilizing agent and co-emulsifier in the emulsion polymerization of styrene, acrylics, and vinyl acetate.
• Wetting and dispersing aid in agricultural chemical formulations such as herbicides and pesticides.
• Foam booster and viscosity modifier in detergent and personal care products.
• Intermediate in the synthesis of more complex specialty surfactants and sulfonated derivatives.
• Additive for improving the stability and performance of textile processing auxiliaries and dyeing baths.
