Methyl substituted propyl-substituted pentamethyl indane derivatives processes for producing same and perfumery uses thereof

Abstract

Described are methyl, substituted propyl-substituted pentamethyl indane derivatives defined according to the structure: ##STR1## wherein R.sub.1 represents hydroxyl or methyl; and R.sub.2 represents hydrogen, chloro or OR.sub.6 ; and R.sub.3 represents hydrogen or methyl with the provisos: (i) when R.sub.1 is hydroxyl, R.sub.2 is hydrogen and R.sub.3 is methyl; and (ii) when R.sub.1 is methyl, one of R.sub.2 is chloro or OR.sub.6 and R.sub.3 is hydrogen augmenting, enhancing or imparting aromas in or to perfume compositions, colognes and perfumed articles including but not limited to solid or liquid anionic, cationic, nonionic or zwitterionic detergents, perfumed polymers, fabric softener compositions, fabric softener articles, cosmetic powders and hair preparations. Also described are processes for preparing such methyl, substituted propyl-substituted pentamethyl indane derivatives using as a starting material the mixture of compounds defined according to the structure: ##STR2## also know as GALAXOLIDE.RTM. (trademark of International Flavors & Fragrances Inc.).
