Science
Mechanism of Action
It functions as a vapor-permeable occlusive, creating a protective film that significantly curbs transepidermal water loss (TEWL) without suffocating the skin. Additionally, it acts as a rheology modifier, improving the spreadability of formulations and increasing the wear-time of active ingredients on the skin surface.
Research
Clinical Evidence
High confidence15%
Key findings
- 01 A 2021 CIR safety assessment confirmed that concentrations up to 15% are effective for skin conditioning and are not dermally absorbed due to their high molecular weight.
- 02 OECD TG 404 tests demonstrated that even at 100% concentration, the ingredient remains non-irritating, validating its safety in concentrated anhydrous products.
Transparency
Dusting Analysis
While often used at lower levels for texture enhancement, concentrations below 1% may not provide the significant barrier repair and occlusive benefits noted in clinical evaluations.
The Formula
Formulation
Stability
A chemically inert silicone wax with a melting point of 66-72°C. It must be integrated into the oil phase and fully melted to ensure a homogenous emulsion.
Synergies
- Heavy botanical waxes
- Mineral UV filters
- Volatile silicones
Conflicts
- High-viscosity aqueous systems without emulsification
- Incompatible with formulas prone to recrystallization without proper solvency
Safety
Safety Profile
Safe for topical applications; however, it is not recommended for airbrush or aerosol delivery systems due to potential inhalation risks associated with small particles.
