Science
Mechanism of Action
This fluorocarbon acts on the skin primarily by forming a stable, low surface tension film that aids in conditioning and provides a waterproof barrier. Its inert nature ensures chemical stability within formulations, functioning effectively as a solvent without impeding pore function.

Formulation
Stability
The substance exhibits robust stability under standard conditions of use, storage, and transport, demonstrating significant resistance to degradation. Hydrolysis rates are negligible across the environmentally relevant pH range of 4 to 9.
Safety
Safety Profile
Perfluoroperhydrophenanthrene is identified as a PFAS (per- and polyfluoroalkyl substance). The Environmental Working Group (EWG) considers it unacceptable for EWG Verified products due to concerns including enhanced skin absorption, high use restrictions, moderate endocrine disruption potential, high persistence and bioaccumulation, and moderate non-reproductive organ system toxicity. The FDA has indicated that the safety of this, and most other intentionally added PFAS in cosmetics, cannot be definitively established due to insufficient toxicological data.
