Science
Mechanism of Action
This polymer operates by forming a breathable, protective film upon application to the skin's surface. This film modifies formulation texture and can aid in water resistance, with broader polyurethane applications also demonstrating support for cellular adhesion and mimicking skin's biomechanical properties.

Stability
Precise pH stability data for POLYURETHANE-95 is not available. However, polyether-based polyurethanes generally exhibit superior hydrolytic stability compared to polyester-based variants. A related compound, Polyurethane-35, shows stability within a pH range of 4.5 to 7.0.
Conflicts
- Formulations containing residual diisocyanate monomers from the synthesis process pose a risk of irritation and sensitization.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel assessed 66 polyurethane ingredients, concluding their safety in cosmetic applications, particularly when formulated to be non-sensitizing and without detectable residual isocyanate monomers. While POLYURETHANE-95 is not explicitly listed, it falls under this generally recognized safe class. Some polyurethanes receive FDA approval for specific medical or food contact uses, indicating general material safety, but this does not directly regulate cosmetic use. A specific SCCS opinion for POLYURETHANE-95 is currently unavailable.
