Science
Mechanism of Action
Disiloxane primarily functions as an inert solvent and carrier, facilitating the uniform distribution of active ingredients across the skin's surface. Its low viscosity and high volatility allow for quick evaporation, leaving behind a soft, silky feel without residual tackiness or oiliness. Beyond its solvent properties, Disiloxane forms a vapor-permeable film that can contribute to improved moisture retention and hydration. It also imparts 'slip' to formulations, enhancing the user experience from application through dry-down, and acts as an antifoaming agent.

Stability
Disiloxane itself exhibits a neutral pH in its raw state. As a silicone, it generally demonstrates high stability against degradation from UV radiation, acids, alkalis, and ozone. However, formulators should be aware of the silicon-oxygen bond's hydrolytic stability, which can be compromised under strong alkaline conditions, potentially impacting long-term product integrity.

Safety
Safety Profile
Disiloxane is broadly considered safe for cosmetic applications and has been deemed suitable for formulation by regulatory bodies. It is noted as non-comedogenic and vegan-friendly. While specific CIR assessments for Disiloxane were not found, the CIR Expert Panel has affirmed the safety of similar silicone polymers (e.g., Dimethicone) for cosmetic use, including for teens and children, primarily due to their low skin absorption. Concerns regarding inhalation exposure of larger dimethicone polymers in airbrush cosmetics do not directly apply to typical topical uses of Disiloxane.
