Science
Mechanism of Action
It functions primarily as a perfuming agent by interacting with olfactory receptors. In a formulation context, it acts as a fixative, lowering the vapor pressure of more volatile aromatic molecules to prevent rapid evaporation and maintain the product's intended scent profile over time.
Research
Clinical Evidence
Medium confidence0.1%
Key findings
- 01 IFRA Amendment 51 established a 0.1% ceiling for leave-on facial applications based on a No Expected Sensitization Induction Level (NESIL) of 1700 µg/cm².
- 02 A large-scale RIFM patch test indicated no immediate adverse reactions in participants, though it remains classified as a potential sensitizer.
Transparency
Dusting Analysis
Because it is a regulated fragrance allergen, concentrations above 0.001% must be disclosed on labels. It is rarely 'dusted' for marketing claims; rather, it is used at very low levels strictly for its aromatic function.
The Formula
Formulation
Stability
Susceptible to oxidation which may convert the alcohol into anisic acid or aldehyde. High-water formulations may experience the 'ouzo effect,' resulting in unwanted turbidity.
Synergies
- Fragrance fixatives
- Lipophilic solvents
Conflicts
- Strong oxidizing agents
- Strong acids
Safety
Safety Profile
Regulated as a potential allergen by the EU and IFRA. Must be declared on INCI lists if it exceeds 0.001% in leave-on products.

Verdict
A precise aromatic stabilizer that provides a sophisticated scent profile but offers no direct physiological benefit to the skin.
