Science
Mechanism of Action
It functions by creating a hydrophobic, non-polar film across the stratum corneum. This physical barrier effectively traps moisture to prevent trans-epidermal water loss (TEWL) while simultaneously shielding the skin surface from external environmental aggressors.
Research
Clinical Evidence
High confidence15%
Key findings
- 01 Clinical assessments indicate that C21-28 alkanes at 10-20% concentrations significantly stabilize mineral formulations and reduce moisture evaporation without contributing to a heavy skin feel.
- 02 Comparative data suggests these hydrocarbons serve as effective, non-comedogenic alternatives to petrolatum in balm and stick formats, providing equivalent barrier support.
Transparency
Dusting Analysis
While often used at lower levels for simple viscosity control, clinical skin-protecting benefits require concentrations above 5%. Its inclusion at trace amounts (<1%) suggests it is being used merely as a processing aid rather than an active skin-conditioning agent.
