What is the IFRA status and EU allergen declaration for this michelia leaf oil?
This michelia leaf oil is IFRA-compliant when used within the category limits for linalool and — critically — for methyleugenol (STD_100), which is present at ~0.25% and is a carcinogen (IARC Group 2B). EU cosmetics law (Regulation 1223/2009, updated by 2023/1545) requires linalool to be declared as an allergen above labelling thresholds; methyleugenol is also a named substance in IFRA STD_100.
IFRA & EU Allergen Data (Typical Batch)
| Allergen | Typical content | Key limits |
|---|---|---|
| Linalool | ~89% (main constituent) | EU labelling: >0.001% (leave-on) / >0.01% (rinse-off) in finished product |
| Methyleugenol | ~0.25% | IFRA STD_100: e.g. Cat5B face cream ≤0.00021%, Cat9 shampoo ≤0.0017%, Cat12 candle ≤0.066% |
| β-Phenethyl alcohol | ~0.17% | EU 2023/1545 allergen — declare if above threshold |
| α-Terpineol | ~0.14% | EU 2023/1545 allergen — declare if above threshold |
| trans-Nerolidol | ~3.5% | Allergen screening per EU 2023/1545 |
- IFRA 51st Amendment STD_100 for methyleugenol is the key constraint for cosmetics: compute your finished-product level from the actual batch COA
- Because linalool is ~89% of the oil, any finished product containing even 0.1% of this oil will exceed the EU linalool labelling threshold
- We supply a ready-made EU-format allergen declaration sheet and IFRA compliance data with every cosmetic-grade order
- The declaration values are batch-specific; always use the values on the COA of the actual batch you purchased
