Science
Mechanism of Action
This ingredient functions by creating a robust, yet adaptable, polymeric film directly on the skin's surface. As a fluoro-modified silicone resin, it physically establishes a barrier that efficiently repels both water and oil. This action effectively prevents cosmetic product degradation and transfer, significantly extending the adherence and sustained aesthetic of facial and color cosmetic applications.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated the safety of 'trifluoropropyldimethyl/trimethylsiloxysilicate', a closely related compound, alongside other silylates and surface-modified siloxysilicates. These were deemed safe as used, provided final products are formulated to prevent irritation or sensitization of the respiratory tract. A broader CIR assessment of 18 related polysilsesquioxanes also found them safe in cosmetics, noting their large, insoluble molecular structure renders them unlikely to penetrate the skin and thus pose low concerns for dermal irritation or sensitization. No specific SCCS opinion or FDA status for this exact ingredient was identified.
