Abstract: Described are processes and compositions for augmenting or enhancing the flavor and/or aroma of consumable materials including foodstuffs, chewing gums, medicinal products, toothpastes, perfumes, colognes, and perfumed articles using as the essential ingredient at least one C.sub.10 -terpene alkyl, alkenyl, haloalkenyl, and alkynyl ether and diether having the formula:(C.sub.10 -TERPENYL) (O-R.sub.1).sub.nwherein n is 1 or 2; the terpene group is a moiety having one of the structures: ##STR1## AND R.sub.1 is one of C.sub.1 -C.sub.4 alkyl, C.sub.3 or C.sub.4 alkenyl, C.sub.3 alkynyl, or C.sub.3 haloalkenyl. The compounds wherein R.sub.1 is C.sub.2 -C.sub.4 alkyl, C.sub.3 or C.sub.4 alkenyl, C.sub.3 alkynyl or C.sub.3 haloalkenyl are novel compounds.

Abstract: Described is a tobacco product having added thereto an amount sufficient to augment or enhance the flavor or aroma of a tobacco product particularly on smoking, of one or more thiazoline compounds having the generic structure: ##STR1## wherein, X is one of: ##STR2## and wherein, one of R.sub.1 or R.sub.2 is methyl and the other of R.sub.1 or R.sub.2 is hydrogen; processes for producing such tobacco products and flavor formulations for use in conjunction with tobacco products containing one or more of such thiazoline compounds.

Abstract: Perfume and fragrance compositions and perfumed articles including soaps, detergents, powders, as well as colognes containing 2-alkyl-substituted-4,5-dimethyl thiazolines having the structure: ##STR1## wherein R.sub.1 and R.sub.3 are the same or different, and each is selected from the group consisting of methyl and hydrogen, which impart thereto chocolate-like, fresh ground coffee-like, green, cucumber, dill aromas and yielding on dry-out floral, natural tuberose-like, orris-like nuances.
