What does this ingredient do in an antiperspirant?
It contributes to the scent of the composition; according to COSMILE Europe it occurs in nature and is used in perfumes and scented cosmetics. CosIng lists its functions as fragrance and flavouring.
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.
In the EU it is on the list of fragrance allergens (Regulation 1223/2009, Annex III, entry 69): it must be named separately in the ingredient list above 0.001% in leave-on and 0.01% in rinse-off products. Regulation 2023/1545 extended this list and updated existing entries; the new rules apply to products placed on the market from 31 July 2026.
The 2012 SCCS opinion classifies it as an established contact allergen in humans, with 101 to 1,000 positive patch-test reactions described, and lists it among the fragrance allergens of special concern. In the skin it can be converted to cinnamal, so reactions to the two substances often go together.
Not cinnamal (Cinnamal) or Amylcinnamyl Alcohol: these are separate entries on the EU allergen list. Nor is it ethanol: here "alcohol" names the chemical class and does not make the formula alcohol-based.
