Dusting Analysis
This ingredient is not commonly dusted, but its use is strictly regulated to 0.8% by IFRA due to the risk of phototoxicity, preventing high concentrations in formulations.
The Formula
Formulation
Stability
Highly volatile and susceptible to oxidation, its terpenes can polymerize upon exposure to air. Stabilization methods like cyclodextrin inclusion or microencapsulation are crucial to maintain efficacy and bioavailability.
Conflicts
- Strong oxidizing agents
- UV light (causes phototoxic reactions)
- High temperatures during processing (leads to loss of volatile ligustilides)
Safety
Safety Profile
Not formally reviewed by CIR but regulated by IFRA due to phototoxic furocoumarins. While FDA lists it as GRAS for food, its skincare application is limited by this phototoxicity concern.
