Mechanism of Action
DIMETHICONE/MERCAPTOPROPYL METHICONE COPOLYMER functions as a hydrophobic, viscoelastic polymer, forming a continuous film upon application to the skin. This ultra-thin film establishes a physical barrier, effectively preventing the ingress of exogenous substances and minimizing moisture evaporation. Its robust film-forming properties contribute to enhanced skin conditioning and protection against external factors such as chemicals, UV radiation, and pollution, while simultaneously imparting a smooth, slippery feel.

Safety Profile
The CIR Expert Panel has concluded that Dimethicone, Methicone, and Substituted-Methicone Polymers, including this ingredient, are safe for use in cosmetic formulations when specifically formulated to be non-irritating. The US FDA considers this ingredient safe at low concentrations for its role as a skin protectant. However, data are presently insufficient to ascertain safety for use in products that may lead to incidental inhalation, such as those applied via airbrush devices.
