The present invention relates to methods of using certain unsaturated derivatives of 2,6,6-trimethyl-cyclohexane-1-acetonitrile as perfuming ingredients. These compounds are valuable patchouli odorants.

Perfuming nitriles

The present invention relates to the use as perfuming ingredient of 1-oxaspiro[2.11]tetradecane, as well as to the perfuming compositions or perfumed articles containing said compound.

Spiroepoxy-macrocycle as perfuming ingredient

Utilization of cyclic compounds as perfuming ingredients

2-indanmethanol derivatives and their use in perfumery

Compounds consisting of indan derivatives of the formula: ##STR1## Wherein X or Y represents an aldehyde or an acetal group and the other represents a hydrogen, and R represents a hydrogen or a methyl group and the t-butyl group is at the 5 or 6 position of the phenyl ring. Where these compounds are useful as perfuming ingredients for the preparation of perfuming compositions and perfumed articles to which they impart floral odor notes.

Aromatic compounds and their use in perfumery

Process for the preparation of alkyl 3-oxo-2-pentyl-1-cyclopentene acetates starting from an epoxy-ester of formula ##STR1## wherein R designates a lower linear or branched alkyl radical of C.sub.1 -C.sub.6 and wherein the wavy line stands for a C--C bond of cis or trans configuration via an isomerization process.
