Uses of alpha methyl styrene dimers in perfumery processes and products

Abstract

A process is described for providing clear extended compositions of essential oils which comprises a composition of an essential oil and an extender material miscible with said essential oil which does not appreciably alter the aroma of the essential oil insofar as its quality or strength is concerned, the proportion of essential oil in extender material being from about 70% up to about 99%, said extender material being a dimerization product of an alpha methyl styrene or a methyl or other C.sub.2 -C.sub.4 lower alkyl homologue thereof or hydrogenated derivative thereof or mixture of same, having one of the generic structures: ##STR1## wherein R.sub.3 and R.sub.4 are the same or different and each represents hydrogen or methyl or other C.sub.2 -C.sub.4 lower alkyl and wherein the dashed lines and wavy lines represent carbon-carbon single bonds or carbon-carbon double bonds with the proviso that when there is one double bond present only the wavy line is a double bond and when there is more than one double bond present, the ring containing the dashed lines and the wavy line is a benzene ring and wherein the line represents either a carbon-carbon single bond or no bond.
