On the label

Named on 4% of the 6,851 perfume ingredient lists we hold (265 perfumes).

EU
Annex III, entry 339. Must be named above 0.001% in leave-on products (0.01% rinse-off).
Great Britain
Not on Great Britain's list. It came to the EU list in 2023 and a GB label need not name it.

A list that does not name it does not prove it is absent: brands only have to name it above the threshold.
