Contact allergens

This perfumed molecule is used as a fragrance in perfumes, a flavoring agent in soft drinks, ice creams, dentifrices, pastries, chewing-gum, etc. It can induce both contact urticaria and delayed-type reactions. It can be responsible for dermatitis in the perfume industry or in food handlers. Cinnamic aldehyde is contained in “fragrance mix.” As a fragrance allergen, it has to be mentioned by name in cosmetics within the EU.
