Questions

Why is citronellol restricted in Europe?
Citronellol is one of 26 fragrance allergens the EU requires to be labeled by name on cosmetics. While most users tolerate it without issue, a minority of people develop skin sensitization to this rose-scented fragrance compound, so labeling ensures consumers with known sensitivities can identify and avoid it.
Am I allergic to citronellol?
Contact allergy to citronellol is uncommon, but if you have a history of fragrance sensitivity or react to products with rose or geranium scent, you may want to avoid it. A dermatologist can perform a patch test if you suspect fragrance allergy.
