Key findings
- 01 Quantitative risk modeling supports 0.13%-0.78% as safe-use concentrations for leave-on products to minimize sensitization risks.
- 02 A 7.46% concentration is a calculated safe maximum for rinse-off formulations based on skin sensitization modeling.
- 03 Animal models demonstrated significant wound-healing activity at 20-40%, with 40% showing superior collagen deposition.

Stability
Hydrogenation significantly improves oxidative stability compared to the standard extract, remaining stable in emulsions up to pH 7.0.
Conflicts
- Strong oxidizing agents
- High heat during the water phase (should be added during the cooling phase or oil phase)
Safety
Safety Profile
While the raw extract is banned in food due to beta-asarone carcinogenicity, the hydrogenated version for cosmetics is processed for stability and requires limiting asarone isomers to ~100ppm in finished products.
