Science
Mechanism of Action
Inhibits tyrosinase activity by binding to the enzyme's active site and quenching its fluorescence, thereby blocking the oxidation of L-DOPA in melanin synthesis pathways. Additionally exhibits antimicrobial effects through electrophilic interactions that disrupt bacterial cell wall integrity.
Research
Clinical Evidence
Medium confidence0.06%
Key findings
- 01 Potent tyrosinase inhibition with IC50 values of 0.075 mM for monophenolase and 0.049 mM for diphenolase activity
- 02 Significant antibacterial activity against S. aureus and E. coli, outperforming unsubstituted cinnamaldehyde
Transparency
Dusting Analysis
Primarily used as a fragrance component with experimental brightening applications; not commonly used for dusting marketing claims
The Formula
Formulation
Stability
Susceptible to oxidation forming 2-bromocinnamic acid under air exposure or extreme pH conditions. Requires opaque, airtight storage containers for stability maintenance.
Conflicts
- Amines (forms Schiff bases)
- Strong oxidizing agents
- Nucleophilic compounds
Safety
Safety Profile
EU Annex III listed masking agent with mandatory labeling requirements when exceeding 0.001% in leave-on products due to cinnamic derivative sensitization potential

Verdict
While showing theoretical promise for tyrosinase inhibition, high sensitization risk and limited clinical validation make it unsuitable for precision skincare applications.
