Sodium 4-n-Octylbenzenesulfonate is widely used as a surfactant in various industrial and household applications. It is particularly effective in detergents and cleaning products due to its ability to reduce surface tension, allowing for better removal of dirt and grease. In the textile industry, it is employed as a wetting agent and dye dispersant, ensuring even color distribution and improved fabric processing. Additionally, it finds use in emulsion polymerization, where it acts as an emulsifier to stabilize polymer particles during the production of synthetic rubbers and plastics. Its role in agricultural formulations includes enhancing the spread and penetration of pesticides and herbicides on plant surfaces. Furthermore, in the paper industry, it aids in fiber dispersion and enhances the uniformity of the paper sheet.
