Science
Mechanism of Action
Functions as a non-polar solvent that dissolves oil-based ingredients and reduces formulation viscosity for improved spreadability. In specialized delivery systems, it facilitates the transport of active compounds into the upper stratum corneum layers without compromising skin barrier integrity.

Key findings
- 01 Effective as primary solvent in delivery systems but classified as Category 2 skin irritant at these concentrations
- 02 Successfully enhances active ingredient penetration in nanoporous delivery systems while maintaining skin barrier integrity
Transparency
Dusting Analysis
Concentrations above 15% may indicate formulation reliance on this potentially irritating solvent rather than gentler alternatives
The Formula
Formulation
Stability
Demonstrates excellent thermal stability under standard storage conditions and remains stable across pH 3-10 due to its non-reactive hydrocarbon structure
Synergies
- Lipophilic actives
- Oil-based carriers
- Waterproof formulations
Conflicts
- Strong oxidizing agents
- Strong acids
- Nitrating agents
Safety
Safety Profile
Safety depends on proper refining to ensure PAH content remains below 3%. May cause reversible skin irritation at high concentrations but does not induce sensitization.
