Abstract
The present invention relates to compounds of formula wherein one R group is a hydrogen atom and the other is a hydrogen atom or a C1-3 alkyl group; and each carbon-carbon double bond of said compound, independently from each other, can be in a configuration Z or E or a mixture thereof; which are useful perfuming ingredients.
Claims18
A compound of formula (I)
- wherein one R group is a hydrogen atom and the other is a hydrogen atom or a C1-3 alkyl group, wherein the compound (I) is in the form of a mixture of stereoisomers (4E,8E), (4Z,8E) and (4E,8Z), wherein the w/w ratio of (4E,8E)/[(4Z,8E)+(4E,8Z)] is between 20/80 and 1/99, or between 80/20 and 99.5/0.5.
A method of use of a compound of formula (I) wherein the method comprises imparting a hedonic effect through application of a compound of formula (I) as a perfuming ingredient
- wherein one R group is a hydrogen atom and the other is a hydrogen atom or a C1-3 alkyl group;
- and each carbon-carbon double bond of the compound (I), independently of each other, can be in a configuration Z or E or a mixture thereof.
