Abstract The physicochemical properties of sodium p‐perfluorononenyloxy benzene sulfonate (OBS) in aqueous solution were investigated. Compared to linear alkylbenzene sulfonate (LAS), OBS has a lower critical micelle concentration (CMC) and a low surface tension at the CMC. At the same concentration, OBS shows lower dynamic surface tension than LAS indicating faster wetting kinetics. In aqueous solution, OBS forms large spherical vesicles above the CMC. OBS shows excellent dynamic wetting properties on low‐energy surfaces. The superior properties of OBS make it ideal for use in many industry fields.
