Abstract
This invention provides smoking compositions which contain a novel flavorant-release additive. Under cigarette smoking conditions, a combustible filler and/or paper wrapper additive such as 2-(3-hexyl-2-hydroxy-4-phenyl-3-buten-1-yl)--3,5,6-trimethylpyrazine releases pyrazine and cinnamaldehyde type of volatile flavorants into the cigarette smoke: ##STR1## A present invention flavorant-release additive is represented by the formula ##STR2## where R is hydrogen or methyl, R.sup.1 is hydrogen or a C.sub.1 -C.sub.10 alkyl substituent; and R.sup.2 is hydrogen or a C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy substituent.
Claims22
A smoking composition comprising an admixture of (1) combustible filler selected from natural tobacco, reconstituted tobacco and tobacco substitutes, and (2) between about 0.0001-5 weight percent, based on the total weight of filler, of a flavorant-release additive corresponding to the formula:
- ##STR16## where R is hydrogen or methyl, R.sup.1 is hydrogen or a C.sub.1 -C.sub.10 alkyl substituent;
- and R.sup.2 is hydrogen or a C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy substituent.
A cigarette smoking product comprising (1) a combustible filler selected from natural tobacco, reconstituted tobacco and tobacco substitutes, and (2) a paper wrapper which has incorporated therein a flavorant-release additive corresponding to the formula:
- ##STR17## where R is hydrogen or methyl, R.sup.1 is hydrogen or a C.sub.1 -C.sub.10 alkyl substituent;
- and R.sup.2 is hydrogen or a C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy substituent.
