Science
Mechanism of Action
Polysilicone-24 operates on multiple fronts. As a skin conditioning agent, it aids in restoring and improving the skin's tolerance to external factors by incorporating emollient and humectant properties to prevent dehydration. In its role as a skin protectant, it creates a physical barrier on the skin's surface, defending against harmful substances, irritants, allergens, and pathogens. Furthermore, within a formulation, it acts as a light stabilizer, preventing the degradation of light-sensitive ingredients and thus extending product efficacy and shelf-life.

Stability
As a silicone chemical compound and polymer, Polysilicone-24 exhibits high inherent chemical stability. While specific pH and temperature stability data for Polysilicone-24 are not available, related polysilicones like Polysilicone-15 have shown stability across acidic to slightly basic environments (pH 4.0–5.0) and at elevated temperatures, suggesting a generally robust profile for this class of ingredient.
Safety
Safety Profile
While Polysilicone-24 has not been directly reviewed by CIR, SCCS, or FDA panels, it is generally considered safe for cosmetic applications. It's important to note its reported potential for high bioaccumulation and environmental persistence. For context, the CIR Expert Panel deemed the related ingredient Polysilicone-11 safe for cosmetic use at concentrations up to 19.9% in other skincare preparations.
