Beta-Caryophyllene
Beta-Caryophyllene must be declared in the EU and Northern Ireland, but it is NOT on the Great Britain list: GB retains the older, shorter list and has not adopted Reg (EU) 2023/1545.
Identity
| Name in the ingredient list | Beta-Caryophyllene |
|---|---|
| CAS / EC number | 87-44-5 / EC 201-746-1 |
| EU Annex III entry | 332 |
It was ADDED to the EU list by Reg (EU) 2023/1545, so products made for the older 26-entry list may need relabelling.
When it must appear on the label
Beta-Caryophyllene may be present as a constituent of essential oils or fragrance compounds. It must be named individually in the ingredient list when its total concentration in the finished product exceeds 0.001% in leave-on products (lotions, balms) or 0.01% in rinse-off products (soap, shower gel), summed across every fragrance source in the recipe. Below the threshold it stays within the collective term "Parfum".
United States: no individual fragrance-allergen labelling is in force yet (MoCRA rulemaking pending); fragrance is declared collectively as "Fragrance".
