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 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
