Science
Mechanism of Action
This modified dimethicone-type silicone functions by depositing a thin, vapor-permeable film upon the skin's surface. This protective layer is effective in reducing moisture evaporation, thereby contributing to enhanced skin hydration. Its inherent low surface tension ensures excellent spreading quality, resulting in a desirable smooth and silky tactile sensation. Furthermore, this film can subtly occupy fine lines and wrinkles, offering a temporary aesthetic plumping effect.

The Formula
Formulation
Stability
Amodimethicone, the base compound, maintains stability within a pH range of 5.5 to 7.0. In acidic conditions, its amine groups undergo protonation, acquiring a positive charge, which is a key consideration for formulation stability and interaction.
Conflicts
- Formulations should avoid combination with cationic surfactants, as this may lead to irritation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined Amodimethicone, including its derivatives like PG-AMODIMETHICONE, to be safe for use in cosmetic formulations. Its high molecular weight suggests negligible absorption into the skin, supporting its overall safety profile. The US FDA also recognizes Butoxy Peg-4 Pg-Amodimethicone as a safe skin protector at low concentrations due to its poor skin absorption. While generally well-tolerated, rare individual allergic reactions are possible.
