Science
Mechanism of Action
This ingredient functions by creating a microscopic yet cohesive film across the skin's surface. This precisely formed barrier acts as a physical shield, reducing direct exposure to damaging external factors such as chemical irritants, UV radiation, and environmental pollutants, thereby enhancing skin defense.

Stability
Polysilicone-31, consistent with other silicone compounds, demonstrates high chemical stability across typical cosmetic formulation conditions.
Safety
Safety Profile
While Polysilicone-31 lacks a specific review by the CIR, it is generally considered safe for topical cosmetic applications. Its inclusion as an 'Approved Chemical Name' in Canada's Natural Health Products Ingredients Database (NHPID) suggests a level of regulatory acceptance, despite observations of high bioaccumulation and persistence.
