Abstract
Described are methods for augmenting or enhancing the aroma of perfumes and perfumed articles by adding thereto perfume aroma augmenting or enhancing quantities of C.sub.10 -branched olefin mixtures produced by dimerizing isoamylene, (2-methyl-2-butene) as well as perfume compositions, colognes and perfumed articles including solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, hair preparations and deodorant compositions as well as bleaching compositions containing same.
Claims3
A process for augmenting or enhancing the aroma of a consumable material selected from the group consisting of perfume compositions and colognes comprising the step of adding to a perfume composition or a cologne base, an aroma augmenting or enhancing quantity of a composition of matter consisting essentially of compounds produced by reacting two moles of diisoamylene with each other in the presence of an acid catalyst, thereby producing at least one compound defined according to the generic structure:
- ##STR10## wherein, R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 represent hydrogen or methyl with the provisos that (i) at least one of R.sub.3 and R.sub.4 represents methyl;
- (ii) the sum of the carbon atoms in each of R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 is 3;
- and (iii) R.sub.1 and R.sub.2 each represent hydrogen when R.sub.5 is methyl.
