Does this eucalyptus leaf oil require an IFRA allergen declaration?
Eucalyptus oil itself is not one of the 26 (or the new 80) EU cosmetic allergens, and its main component 1,8-cineole is not on the IFRA restricted allergen list. However, the oil can contain trace levels of naturally occurring fragrance allergens such as limonene and linalool that appear in the IFRA/EU allergen declaration lists.
Allergen Declaration
| Component | EU 2023/1545 list? | IFRA status |
|---|---|---|
| 1,8-Cineole (eucalyptol) | No | Not restricted as an allergen |
| Limonene (trace) | Yes — listed | Quantity declared if above labelling threshold |
| Linalool (trace) | Yes — listed | Quantity declared if above labelling threshold |
| α-Terpineol | No (not in the 80) | Safe; no label requirement |
- Per EU Regulation 2023/1545 (in force for products placed on the market after 31 July 2026), any listed allergen above 0.001% in leave-on or 0.01% in rinse-off products must appear on the label with its exact percentage
- We can supply an allergen declaration based on the actual GC-MS data of each batch, so your label quantities are accurate rather than guessed
- Eucalyptus oil is not on the IFRA prohibited list; its use is limited mainly by practical skin-sensitisation considerations rather than a formal standard
- For high-cineole eucalyptus oil, skin exposure guidelines recommend conservative use in leave-on products (typical max use in massage blends ~2-5%)
- Request the batch-specific allergen report at ordering; we generate it from the same GC-MS run as the COA
