Cinnamyl alcohol
Cinnamyl alcohol is listed in Annex III and may only be used under the conditions shown in this record.
This substance is on the EU list of fragrance allergens that must be named individually in the ingredient list, rather than being covered by the word "parfum", once it exceeds 0.001% in a leave-on product or 0.01% in a rinse-off product.
Declaration is a labelling duty under Article 19, not a restriction on use. See the allergen record
Chemical identity and properties
Cinnamyl Alcohol
Cinnamyl alcohol is a primary alcohol comprising an allyl core with a hydroxy substituent at the 1-position and a phenyl substituent at the 3-position (geometry of the C=C bond unspecified). It has a role as a plant metabolite. — ChEBI
