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.

Claim (Index 1):
A method for releasing one or more active volatile aldehydes or ketones which comprises:\n providing a delivery system that includes a compound of formula wherein R 1  and R 2  represent simultaneously or independently a hydrogen atom, a C 1-18  hydrocarbon group or a C 1-18  group that includes one to three oxygen atoms, one to two nitrogen atoms, and/or one sulfur atom, provided that at least one or both of R 1  and R 2  includes one of the C 1-18  groups; wherein R 1  and R 2  are derived from an active aldehyde or ketone of formula (R 1 )(R 2 )C(\u2550O); said aldehyde or ketone having a molecular weight comprised between 80 and 230 g/mol and being a C 5-18  compound; R 3  represent simultaneously or independently from each other, a hydrogen atom, a linear C 1 -C 8  alkyl group, a branched or cyclic C 3 -C 8  alkyl group, a hydroxy group, a methoxy group, an ethoxy group, a 2-hydroxyethoxy group, a 2-ethoxyethoxy group, a (OCH 2 CH 2 ) n OH group, a (OCH 2 CH 2 ) n OCH 3  group, a methylthio group, a dimethylamino group, or a diethylamino group, with n being an integer varying between 2 and 8; and R 4  and R 5  represent, simultaneously or independently from each other, a hydrogen atom, a linear C 1 -C 4  alkyl group, a branched C 3 -C 4  alkyl group, a methoxy group, an ethoxy group, a 2-hydroxyethoxy group, a 2-ethoxyethoxy group, a (OCH 2 CH 2 ) n OH group, a (OCH 2 CH 2 ) n OCH 3  group, a methylthio group, a dimethylamino group, or a diethylamino group, with n having the same meaning as above, wherein at least one R 4  and at least one R 5  are a dimethylamino group; and triggering the release of the one or more active volatile aldehyde or ketone by light.
