Abstract
An aroma mixture for reducing undesired side-stream smoke effects, comprising: (a) one or more aldehydes, selected from the group consisting of saturated, mono- and polyunsaturated aliphatic, alicyclic and aromatic aldehydes containing 4 to 12 carbon atoms; (b) one or more heterocyclic compounds which contain oxygen or nitrogen as hetero atom(s) and at least one hydroxy group or one methyl group, selected from the group consisting of mono- and oligocyclic heterocycloalkanes, heterocycloalkenes and heteroaromatics; and (c) vanillin (4-hydroxy-3-methoxy benzaldehyde).
Claims12
A cigarette including a tobacco rod provided with a cigarette rod covering, improved in that an aroma mixture is applied to the cigarette rod covering, the aroma mixture comprising:
- (a) one or more aldehydes, selected from the group consisting of saturated, mono- and polyunsaturated aliphatic, alicyclic and aromatic aldehydes containing 4 to 12 carbon atoms;
- (b) one or more heterocyclic compounds which contain oxygen or nitrogen as the hetero atoms(s) and at least one hydroxy group or one methyl group, selected from the group consisting of mono- and oligocyclic heterocycloalkanes, heterocycloalkanes and heteroaromatics;
- and
- (c) vanillin, and the cigarette rod covering is double-layered, including an inner layer having the aroma mixture applied thereto and which comprises a highly porous covering paper with an air permeability of 4,000 to 80,000 CORESTA prior to application of the aroma mixture, and an outer layer comprising cigarette paper with an air permeability of 5 to 100 CORESTA, wherein the aroma mixture is applied to the inner layer in encapsulated form, whereby the tobacco rod remains essentially free of the aroma mixture and the side-stream smoke is given a tobacco-like odor.
A cigarette including a tobacco rod provided with a cigarette rod covering, improved in that an aroma mixture is applied to the cigarette rod covering, the aroma mixture consisting essentially of one or more aldehydes of lower hydrocarbons, one or more heterocyclic compounds containing oxygen or nitrogen as hetero atom(s), and vanillin or derivatives thereof having comparable fragrance properties, each having boiling points between 80.degree. C. and 250.degree. C., and the cigarette rod covering is double-layered, including an inner layer having microcapsules containing the aroma mixture applied thereto and which comprises a highly porous covering paper with an air permeability of 4,000 to 80,000 CORESTA prior to application of the aroma mixture, and an outer layer comprising cigarette paper with an air permeability of 5 to 100 CORESTA, whereby the tobacco rod remains essentially free of the aroma mixture and the side-stream smoke is given a tobacco-like odor.
