Science
Mechanism of Action
Functioning primarily as a film-forming agent, this ingredient creates a permeable, continuous barrier on the skin. This film provides protection from external environmental stressors. The Trimethylsiloxysilicate component is key in forming a water-resistant film that can extend makeup wear, while the acrylate crosspolymer elements contribute to increased formulation viscosity and overall stability.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed the constituent polysilsesquioxane and crosslinked alkyl acrylate categories safe for cosmetic use under current practices. However, these conclusions are contingent on specific restrictions: crosslinked alkyl acrylates must not be polymerized in benzene and formulations must be designed to prevent skin irritation. While no specific CIR assessment exists for this exact complex INCI name, related Polymethylsilsesquioxane studies have indicated slight local erythema and dryness in dermal toxicity tests. The FDA status for this precise compound is not explicitly documented, and its SCCS status is unavailable.
