What does this ingredient do in an antiperspirant?
It used to be a fragrance component and was on the list of allergens that had to be named in the ingredient list (Annex III, entry 83).
Part of a system, not a label in isolation
It has no effect on sweating. If it appears in an ingredient list, the formula does not meet current EU requirements: for example, it may be an older version of the formula or a product made for a market outside the EU.
Banned in EU cosmetics since 1 March 2022: Regulation (EU) 2021/1902 moved it to Annex II (prohibited substances, entry 1666) after it was classified as toxic for reproduction, category 1B.
The 2012 SCCS opinion lists it as an established contact allergen in humans, with 11 to 100 positive patch-test reactions reported.
The EU ban is based on its classification for reproductive toxicity, not only on allergenicity; the other substances on the fragrance allergen list remain allowed with labelling and restrictions.
