Science
Mechanism of Action
As a fluorinated silicone polymer, Perfluorobutylethyl Dimethicone forms a highly hydrophobic yet breathable film on the skin's surface. This advanced film acts as a protective shield, significantly reducing transepidermal water loss (TEWL) and bolstering the skin's defense against external aggressors and irritants. The unique fluorine component contributes to its extreme water repellency and wash-off resistance, ensuring long-lasting effects without occluding pores or feeling heavy, thereby promoting a smoother skin texture.

Stability
Silicones are generally stable under heat and resistant to most chemical substances, though exposure to strong acids may affect their integrity. This ingredient is noted to be compatible with a majority of cosmetic formulation components.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed dimethicone and related substituted-methicone polymers, including Perfluorobutylethyl Dimethicone, safe for use in cosmetics when formulated to be non-irritating. Reported concentrations for dimethicone in dermal products can reach up to 85%. Additionally, the FDA permits dimethicone as an active ingredient in over-the-counter skin protectant formulations at concentrations ranging from 1% to 30%.
