Identity
| Name in the ingredient list | Citrus Aurantium Flower Oil |
|---|---|
| Also covered by this entry | Citrus Aurantium Amara Flower Oil; Citrus Aurantium Dulcis Flower Oil |
| CAS / EC numbers | 72968-50-4 / EC 277-143-28028-48-6 / EC 232-433-88016-38-4 |
| EU Annex III entry | 350 |
| Group entry | Several substance forms are declared under this single name. |
Citrus Aurantium Amara Flower Oil and Citrus Aurantium Dulcis Flower Oil share this Annex III entry, and the label must read "Citrus Aurantium Flower Oil" for any of them. A supplier figure given under either name therefore counts toward the same threshold, so add them together before comparing.
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
Citrus Aurantium Flower Oil is itself an essential oil or plant extract, added for its scent or as part of a fragrance compound. 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".
Common questions
Do I have to list Citrus Aurantium Flower Oil on my label?
Citrus Aurantium Flower Oil 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. It must be named individually once it exceeds 0.001% of a leave-on product or 0.01% of a rinse-off product, summed across every fragrance source in the recipe. Below that it stays inside the collective term "Parfum".
