Science
Mechanism of Action
By combining a high-molecular-weight silicone backbone with long-chain alkyl groups (C24-28), this ingredient creates a breathable yet substantive hydrophobic film. This barrier significantly reduces transepidermal water loss (TEWL) and functions as a molecular bridge, allowing organic oils and silicones to blend harmoniously for a uniform skin finish.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 Safety assessments confirm its use as a standard conditioning agent in suncare and lip products at concentrations up to 2%.
- 02 CIR data establishes systemic safety for concentrations up to 15% when utilized as a skin-conditioning and occlusive agent.
Transparency
Dusting Analysis
While often used for texture at lower levels, therapeutic occlusive benefits and formula stability typically require at least 2%. Concentrations below 0.5% in heavy creams are likely for label claims rather than structural integrity.
The Formula
Formulation
Stability
Highly thermally stable up to 80°C with a specific melting point range of 65-75°C, making it ideal for stick formulations and stable emulsions.
Synergies
- Organic botanical oils
- Cyclic siloxanes
- Mineral UV filters
Conflicts
- Pure water phases
- Isopropanol
Safety
Safety Profile
Due to its large molecular size, dermal penetration is negligible. Our standards require high-purity grades to ensure residual cyclic siloxanes remain below 0.01%.
