Science
Mechanism of Action
Forms a continuous, flexible polymer film through its unique tri-component structure: perfluoroalkyl chains provide dual hydrophobic and oleophobic barriers, the dimethicone backbone delivers smooth application and spreadability, while mercaptopropyl groups enhance adhesion to skin proteins for superior staying power.

Dusting Analysis
This high-performance film-former is typically used at effective concentrations rather than trace amounts, as its specialized function requires sufficient polymer density to form protective barriers.
The Formula
Formulation
Stability
Exceptionally stable polymer resistant to thermal degradation and hydrolysis, typically pre-dispersed in volatile silicones like cyclopentasiloxane or isododecane for optimal incorporation.
Synergies
- Volatile silicones for dispersion
- Oil-phase emollients
- Other film-forming polymers
Conflicts
- Purely aqueous systems without oil phase
- Highly polar solvents that may precipitate polymer
Safety
Safety Profile
Classified as a PFAS (Per- and Polyfluoroalkyl Substance) with environmental persistence concerns. Currently unrestricted by FDA/EU but appears on some retailer restricted substance lists due to sustainability considerations.
