Science
Mechanism of Action
As a surfactant, Tridecylbenzenesulfonic Acid functions by lowering the surface tension between various phases, facilitating the emulsification and removal of oils and dirt from the skin. Sulfonic acids are also known to promote skin regeneration through enzymatic exfoliation, breaking down dead skin cells. Additionally, some benzenesulfonic acid derivatives have demonstrated capabilities as UV stabilizers and protectors in cosmetic formulations.

The Formula
Formulation
Stability
This ingredient is generally stable under normal ambient and anticipated storage conditions. Dodecylbenzenesulfonic acid, a closely related analogue, exhibits a pKa of approximately 0.7, indicating its nature as a strong acid that is fully dissociated within the typical environmental pH range of 4 to 9.
Conflicts
- Strong oxidizing agents
- Alkalis (causes liberation of excessive heat)
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that *salts* of Dodecylbenzenesulfonate, Decylbenzenesulfonate, and Tridecylbenzenesulfonate are safe for cosmetic use when formulated to minimize their irritancy potential. However, Tridecylbenzenesulfonic acid itself is classified as corrosive, capable of causing severe skin burns and eye damage. The irritant properties are concentration and pH-dependent, similar to other detergents. No specific SCCS status or direct FDA approval for the acid form was found.
