The present invention primarily concerns the use of compounds of the following formula (I) ##STR00001##
wherein X represents an oxygen atom, a —CHO, an —OH, or a —CH.sub.2OH group, a single bond or a double bond is present at the respective location of one of the dotted lines, at least one double bond is present when X is an OH group, and the 3-isopentyl or 3-isopent-2-enyl residue is connected to the ring in the ortho, meta, or para position to the X group, as perfuming and/or flavouring agents. The invention further relates to fragrance and flavour compositions containing one or more of these compounds, perfumed or flavoured articles comprising one or more of these compounds and corresponding processes for imparting, modifying and/or enhancing certain odour notes.

The compound (3aS,4aR,5S,7aS,9R,9aR)-2,2,5,8,8,9a-hexamethyloctahydro-4H-4a,9-methanoazuleno[5,6-d][1,3]dioxole, compositions and consumer products comprising the compound, methods of making the compound, and the various uses of the compound.

The present invention relates to the perfumery industry. More particularly, the present invention relates to assays and methods for screening and identifying compositions and/or ingredients that intensify a subjects perception of target odorant compounds based on the use of particular olfactory receptors activated by the target odorant compound.

Disclosed are a method for manufacturing a microcapsule including a fragrance oil, and a microcapsule containing a fragrance oil. In the method for manufacturing a microcapsule including the fragrance oil, there is provided a fragrance oil-containing microcapsule which has an increased distribution of individual primary particles because the aggregation of the primary particles is suppressed even when the microcapsule is manufactured in a large quantity, has a uniform particle shape and excellent surface characteristics, shows an excellent strain recovery capability with respect to external pressure due to the high yield stress, and enables a stable support of the fragrance oil because the collapse of the microcapsule is suppressed. Also, there are provided a fragrance oil-containing microcapsule and a dispersion including the same, wherein the fragrance oil-containing microcapsule shows an excellent long-term fragrance diffusion-lasting property of the fragrance oil and has controlled release characteristics with respect to the fragrance oil.
