Abstract
This invention provides tobacco and non-tobacco smoking compositions which contain a quaternary ammonium compound as a flavorant additive. In one of its embodiments this invention provides tobacco compositions which contain a quaternary ammonium flavorant additive such as ##STR1## Under smoking conditions the above illustrated pyridinium additive and its pyrolysis products flavor the mainstream smoke.

A smoking composition comprising an admixture of (1) combustible filler selected from natural tobacco, reconstituted tobacco and non-tobacco substitutes, and (2) between about 0.001 and 5 weight percent, based on the total weight of filler, of a quaternary ammonium additive compound corresponding to the formula:
- ##STR16## wherein R, R.sup.1, R.sup.2 and R.sup.3 individually are selected from aliphatic, alicyclic and aromatic radicals containing between 1 and about 8 carbon atoms;
- R and R.sup.1 when taken together with connecting elements form a heteroalicyclic structure, and R, R.sup.1 and R.sup.2 when taken together with connecting elements form a heteroaromatic structure;
- and X is an organic acid anion.
A smoking composition comprising an admixture of (1) combustible filler selected from natural tobacco, reconstituted tobacco and non-tobacco substitutes, and (2) between about 0.001 and 5 weight percent, based on the total weight of filler, of a humectant flavorant additive compound corresponding to the formula:
- ##STR17## wherein, R, R.sup.1, R.sup.2 and R.sup.3 individually are selected from aliphatic, alicyclic and aromatic radicals containing between 1 and about 8 carbon atoms;
- R and R.sup.1 when taken together with connecting elements form a heteroalicyclic structure, and R, R.sup.1 and R.sup.2 when taken together with connecting elements form a heteroaromatic structure;
- and Y is a carboxylate anion containing between 2 and about 12 carbon atoms.
A smoking composition comprising an admixture of (1) combustible filler selected from natural tobacco, reconstituted tobacco and non-tobacco substitutes, and (2) between about 0.001 and 5 weight percent, based on the total weight of filler, of a humectant flavorant additive compound corresponding to the formula:
- ##STR18## wherein R.sup.4, R.sup.5, R.sup.6 and R.sup.7 individually are selected from aliphatic, alicyclic and aromatic radicals containing between 1 and about 8 carbon atoms;
- R.sup.4 and R.sup.5 when taken together with connecting elements form a pyrrolidine structure, and R.sup.4, R.sup.5 and R.sup.6 when taken together with connecting elements form a pyridine structure;
- and Y is a carboxylate anion containing between 2 and about 12 carbon atoms.
