Science
Mechanism of Action
This dimethicone derivative functions by forming a hydrophobic, viscoelastic film on the skin's surface. This barrier effectively minimizes transepidermal water loss (TEWL) and provides protection against external irritants. Additionally, it imparts a desirable non-greasy feel, enhances skin lubricity and shine, and possesses inherent UV-resistance properties. It also contributes to cleansing and emulsification in formulations.

The Formula
Formulation
Stability
When incorporating into formulations, avoid heating this ingredient above 50°C (125°F) if adding directly to the oil phase. Alternatively, it can be seamlessly blended into emulsions once the temperature has cooled to approximately 50°C. Typical usage levels for related compounds range from 1% to 5%.
Safety
Safety Profile
Recognized by the U.S. FDA as a safe skin protectant at lower concentrations. Its high molecular weight restricts skin absorption, contributing to its safety profile. The CIR Expert Panel affirms the safety of dimethicone crosspolymer ingredients, including related compounds like PEG-8 Dimethicone (up to 5.6%), when formulated to be non-irritating, aligning with safe cosmetic practices. No specific SCCS assessment for this exact compound was found, though dimethicone materials have been reviewed.
