Product Usage

Sodium dodecylbenzenesulfonate is one of the most widely used anionic surfactants. In the detergent industry, it is the core detergency component in household laundry powders, dishwashing liquids, and industrial cleaners, offering excellent detergency, emulsifying, and foaming properties. In the textile and dyeing industry, it is used as a penetrating agent and leveling agent to help dyes penetrate evenly. In pesticide formulations, it acts as an emulsifier and dispersant to improve suspension stability. Additionally, it is used in electroplating, leather processing, and emulsification viscosity reduction in oil extraction. Its advantages include hard water resistance, good biodegradability, and high cost-effectiveness, though mild skin irritation should be noted.
