Tetrapropylene benzene sulfonate (TPS) is a chemical compound from the class of sulfonates and an alkyl benzene sulfonate that is effective as an anionic surfactant . Since the tetrapropylene sulfonate, which is highly branched in the alkyl side chain, only biodegrades to around 20-30%, it was replaced by linear alkylbenzenesulfonates (LAS) such as dodecylbenzenesulfonate as early as the 1960s . The foaming of the rivers by TPS led to the first detergent and cleaning agent law in 1961.

Tetrapropylene benzene sulfonate is obtained from 1-dodecene .
