As a natural essential oil, Chuanxiong oil may contain trace levels of naturally occurring fragrance allergens that must be declared per IFRA/EC 1223/2009 when present above labeling thresholds.
Allergen Declaration
| Item | Detail |
|---|---|
| IFRA standard | IFRA 51st Amendment (current) applies to fragrance use |
| Cosmetic labeling | EU/UK EC 1223/2009 Annex III allergens must be declared when ≥0.001% (leave-on) / ≥0.01% (rinse-off) |
| Analysis | GC-MS quantitative allergen screen per batch |
| Report | Allergen declaration sheet issued with COA |
- Chuanxiong oil's phthalide backbone (ligustilide etc.) is not itself an Annex III allergen; declaration depends on the level of individual terpene/alcohol allergens naturally present
- Use-level limits per IFRA categories are assessed for each finished-product application
- We recommend final-formula assessment with the complete allergen sheet before market release
