Abstract
Described are 1-oxo-substituted and unsubstituted isobutyl-4-ethoxy-benzenes and mixtures thereof with bicyclopentadiene derivatives, wherein the 1-oxo-substituted and unsubstituted isobutyl-4-ethoxy-benzenes are defined according to the structure: ##STR1## wherein Y.sub.1 represents one of the moieties: ##STR2## and wherein the bicyclopentadiene derivatives are defined according to the structure: ##STR3## wherein Z.sub.1 and Z.sub.2 represent hydrogen, C.sub.1 -C.sub.3 lower alkyl or C.sub.2 -C.sub.3 acyl and Z.sub.3 represents methyl or hydrogen with the proviso that Z.sub.1 and Z.sub.2 are not both hydrogen, and uses thereof in augmenting, enhancing or imparting aromas in and to perfume compositions, colognes, perfumed polymers and perfumed articles.
