Isoeugenyl Acetate
Isoeugenyl Acetate 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 | Isoeugenyl Acetate |
|---|---|
| CAS / EC number | 93-29-8 / EC 202-236-1 |
| EU Annex III entry | 370 |
It was ADDED to the EU list by Reg (EU) 2023/1545, so products labelled for the familiar 26 (24 still in force by 2023) may need relabelling.
When it must appear on the label
Isoeugenyl Acetate 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".
