- fragrance further possessing an aldehydic
note, reminiscent of citronellal, citrusy,
spicy, recalling the odor of the citronella
leaves. As to its bottom note, it has a
character which is reminiscent of the odor of
3-(4-tert-butyl-1-phenyl)-2-methylpropanal, but
with an even greener connotation and a slightly
orangy aspect

(+)-(1'S)-4-(2',2',3'-trimethyl-3'-cyclopenten-1'-yl)-4-penten-1-al
- a more metallic and aldehydic odor, recalling
that of trans-4-decenal, and the bottom note of
which is more floral and even stronger in the
aqueous character. The use of this latter
compound to enhance the latter odor character in
perfumed compositions and articles is in fact
preferred to that of its
(-)-(1'R)-enantiomer
