Amyl Cinnamal is a fragrance that could be associated with sensitizing mechanisms and/or allergic reactions (1).

Together with 7 other perfume components, Amyl cinnamal is considered an excellent screening agent for contact allergies to perfumes (2).

Regarding the sensitization induced on the skin by fragrances, some non-reactive compounds such as α-isomethyl ionone, benzyl alcohol, amyl cinnamal and farnesol have become reactive after photo-oxidative degradation (3).

In this study an ex vivo comparison of the sensitization potency of different fragrances including Amyl cinnamal which achieved a moderate result (4).

Amyl Cinnamal is a chemical compound used to give jasmine scent to liquid soaps, shampoos, fragrances.

Also allowed in foods, but must be reported on the label as it may cause allergies if in quantities greater than those allowed (0.01% in cosmetics that can be rinsed and 0.001% in creams).
