What does this ingredient do in an antiperspirant?
Contributes to the scent of the blend; since 2023 it has been on the EU extended list of allergens that must be named separately.
Part of a system, not a label in isolation
In an antiperspirant or deodorant it only contributes to the scent and does not reduce sweating. Its presence in the list means the product is fragranced.
EU Regulation 2023/1545 added it to the list of fragrance allergens (Annex III, entry 337): above 0.001% in leave-on and 0.01% in rinse-off products it must be named separately in the ingredient list. New products must comply from 31 July 2026; products already on the market may be sold until 31 July 2028.
The SCCS lists it as an established contact allergen in humans: up to 10 positive reactions reported for the non-oxidised form and 11–100 for the oxidised form. Like linalool, it oxidises in air, which increases its sensitising potential.
Not linalool (Linalool): a related but different substance with its own entry on the allergen list.
