Science
Mechanism of Action
By integrating long-chain C26-28 hydrocarbons into a silicone backbone, this ingredient functions as a hybrid emollient. It forms a hydrophobic, breathable lattice on the skin's surface that significantly reduces transepidermal water loss (TEWL) while acting as a coupling agent that stabilizes emulsions and ensures even pigment distribution.

Key findings
- 01 Demonstrated measurable prevention of moisture loss (TEWL) and enhanced SPF performance through superior film uniformity.
Transparency
Dusting Analysis
While often used at lower levels for texture modification, clinical efficacy for barrier protection and SPF enhancement is typically documented between 4-12%. Concentrations below 1% in barrier-focused products may indicate 'label claim' usage.
The Formula
Formulation
Stability
Highly stable across a broad pH spectrum; requires heating to 46-55°C to incorporate into the oil phase. It offers superior compatibility with organic oils compared to standard dimethicone.
Synergies
- Mineral UV filters
- Organic oils
- Color pigments
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
The 2020 CIR assessment confirms safety in concentrations up to 71.3% in leave-on products, though skincare applications are generally much lower.
