Science
Mechanism of Action
As a volatile silicone, Cyclohexasiloxane functions as a transient carrier fluid, evaporating rapidly from the skin's surface without being absorbed. Its exceptionally low surface tension promotes excellent spreadability, contributing to a smooth, matte finish. It forms a breathable, protective film that minimizes transepidermal water loss, thereby enhancing skin hydration and promoting a soft, supple complexion. Additionally, it acts as an effective emollient and skin conditioning agent.

Stability
Cyclohexasiloxane demonstrates robust chemical stability, resisting degradation or reactivity under typical cosmetic formulation conditions. It maintains a neutral pH and exhibits broad compatibility, integrating seamlessly with a wide array of cosmetic ingredients without inducing destabilizing chemical interactions.
Synergies
- Enhances the efficient delivery and uniform distribution of other active ingredients due to its carrier fluid properties and excellent spreadability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Cyclohexasiloxane as safe under current practices of use and concentration in cosmetics. It is recognized by international regulatory bodies such as the FDA and ECHA as safe for cosmetic applications when adherence to specified concentration limits is maintained. The European Chemicals Agency (ECHA) proposes a restriction of its concentration to 0.1% in cosmetic products, primarily due to environmental considerations. Notably, a 2012 report documented product content of D6 up to 48%, which, upon risk assessment, indicated a potential health risk depending on the specific product type and maximum concentration.
