Science
Mechanism of Action
As a dimethicone by-product, METHACRYLOYLOXYPROPYL DIMETHICONE forms a continuous, ultra-thin hydrophobic film on the stratum corneum. This barrier function prevents excessive water evaporation from the skin and acts as a shield against external stressors. Its film-forming properties also contribute to a refined skin texture, described as smooth and non-greasy, and it offers UV-resistant characteristics.

Stability
This hydrophobic polymer exhibits general stability to heat and oxygen. For optimal formulation, it is recommended to incorporate it into the oil phase and avoid heating above 50°C (125°F). Effective catalyst removal during its synthesis is crucial for maintaining its long-term stability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed dimethicone and its derivatives, including METHACRYLOYLOXYPROPYL DIMETHICONE, deeming them safe for cosmetic use when formulated to be non-irritating. Reported maximum use concentrations for dimethicone itself extend up to 85% for products with dermal contact. The FDA acknowledges dimethicone as a safe skin protectant within concentrations of 1-30%.
