Abstract
A perfume composition comprising an effective amount of at least one alkadienal selected from 4,8-undecadienal and isomers thereof, 4,9-dodecadienal and isomers thereof, and 4,10-tridecadienal and isomers thereof. The isomers of 4,8-undecadienal comprise Z,Z-4,8-undecadienal, E,E-4,8-undecadienal, and mixed Z/E isomers of 4,8-undecadienal; the isomers of 4,9-dodecadienal comprise Z,Z-4,9-dodecadienal, E,E-4,9-dodecadienal, and mixed Z/E isomers of 4,9-dodecadienal; and the isomers of 4,10-tridecadienal comprise Z,Z-4,10-tridecadienal, E,E-4,10-tridecadienal, and mixed Z/E isomers of 4,10-tridecadienal. A composition comprising an effective amount of at least one alkadienal selected from 4,8-undecadienal and isomers thereof, 4,9-dodecadienal and isomers thereof, and 4,10-tridecadienal and isomers thereof. Processes for the preparation of the isomer mixtures of alkadienals are provided. The isomeric alkadienals have a range of fresh, watery, ozone, grapefruit, tangerine, orange peel, aldehydic notes of exceptional strength.
