Trimethylsiloxysilicate
Ingredient Info
Trimethylsiloxysilicate is a silicone-derived ingredient that forms a lightweight, breathable film on the skin's surface. It's used in cosmetics to improve texture, increase viscosity, and help products spread evenly while providing a smooth, non-greasy finish.
Benefits
- Creates a smooth, silky texture in skincare formulations
- Helps products spread evenly and absorb without a heavy feeling
- Improves product stability and prevents caking in powders
- Forms a breathable film that conditions skin without occluding pores
Potential concerns
- Must be formulated to avoid inhalation exposure during application (particularly in powdered or spray products)
- Potential for respiratory irritation if aerosolized; use in aerosolized products requires careful safety testing
Science: The Cosmetic Ingredient Review Expert Panel concluded that trimethylsiloxysilicate is safe as used in cosmetics when formulated to prevent respiratory irritation. Research demonstrates it creates persistent, non-occlusive skin films suitable for delivery of active ingredients, making it a well-established ingredient in modern skincare formulations.
