Abstract
A method for releasing one or more active volatile aldehydes or ketones from a delivery system based on photosensitive acetal or ketal compounds capable of liberating upon exposure to light an active volatile carbonyl compound in a controlled manner from a surface into the surrounding environment. The delivery system can be used to release active substances such as flavors, fragrances, malodor counteractants, insect attractants or insect repellents. The invention also relates to the use of such acetal or ketal compounds in perfumery, as well as in perfuming compositions or perfumed consumer articles.
