Science
Mechanism of Action
This copolymer functions by forming a continuous, hydrophobic film across the skin's surface, effectively creating a barrier against environmental stressors like chemicals, UV radiation, and pollution. As a derivative of Dimethiconol, it deeply conditions the skin, improving hydration, reducing flaking, and restoring suppleness. Its ability to temporarily fill fine lines and wrinkles also contributes to a visually plumped and refined skin texture.

Stability
A minimum pH of 3.0 is recommended for formulations containing dimethiconol and its derivatives to ensure stability and safety, particularly in certain product types. This ingredient, being insoluble in water, can also aid in stabilizing preparations by inhibiting foam formation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Dimethiconol and its related derivatives, including this copolymer, safe for use at current concentrations. This conclusion is primarily based on the large molecular weight of these ingredients, which significantly reduces the likelihood of skin absorption, thereby mitigating concerns regarding systemic toxicity. For certain product types, concentrations up to 30% are considered safe, particularly when formulated with a minimum pH of 3.0. A related compound, Dimethicone, is recognized as a safe skin protectant by the US FDA.
