Abstract
Described are compounds defined according to the structure: ##STR1## wherein R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 represent hydrogen or methyl with the provisos that: PA1 (i) the sum total of carbon atoms in R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 is three; PA1 (ii) when R.sub.7 is methyl, then R.sub.5 and R.sub.6 are both methyl, and PA1 (iii) when either R.sub.3 or R.sub.4 is methyl, then R.sub.7 is hydrogen and wherein R.sub.8 represents hydrogen, acetyl, alkoxyacyl, hydroxyacyl, or alkali metal carboxylate; and R.sub.9 is hydrogen or allyl with the additional proviso that R.sub.8 and R.sub.9 are not both hydrogen. Also described is the use of the subgenus of such compounds defined according to the structure: ##STR2## in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles including solid or liquid nonionic, cationic, anionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, cosmetic powders, hair preparations and the like.
