What does this ingredient do in an antiperspirant?
Adds a citrus note. It is a natural mixture of many substances, so it is counted as one entry rather than as a single substance.
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. A "natural" origin does not make it less relevant for people allergic to fragrance ingredients.
EU Regulation 2023/1545 added it to the list of fragrance allergens (Annex III, entry 351): 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 entry groups bitter orange (Citrus Aurantium Amara) and sweet orange (Citrus Aurantium Dulcis, Citrus Sinensis) peel oils, which may be listed under the common name Citrus Aurantium Peel Oil.
The SCCS lists both bitter and sweet orange peel oils as established contact allergens in humans, with 11–100 positive patch-test reactions reported for each.
Not bergamot oil (Citrus Aurantium Bergamia Peel Oil) or orange flower oil (Citrus Aurantium Flower Oil), which have their own entries on the EU list.
