Science
Mechanism of Action
Vinyltrimethylsilyloxy Silicate functions by creating a durable, yet permeable, film on the skin's surface. This film helps to bind other ingredients, extending wear time and imparting water-resistant properties.

Stability
General silicate stability is influenced by pH; acid conditions can cause polymerization, while higher pH may offer more stability. Optimal pH ranges for this specific ingredient are not available.
Conflicts
- Formulations that could lead to respiratory tract irritation or sensitization, especially via incidental inhalation
- High alkalinity (e.g., pH around 11) can cause skin irritation with some silicates
Safety
Safety Profile
The CIR Expert Panel considers silylates safe when formulated to avoid respiratory tract irritation or sensitization. Care should be taken in spray products where incidental inhalation might occur.
