Abstract
Electrically heated cigarettes used in an electrical smoking system include a flavoring-release additive and sorbent effective to remove one or more gas-phase constituents of mainstream tobacco smoke. The flavoring-release additive includes gamma cyclodextrin and at least one flavoring. Flavoring is released in a cigarette upon the flavoring-release additive reaching at least a minimum temperature during smoking. The flavoring-release additive can have various forms including, for example, powder and films.
Claims19
A flavoring-release additive for a smoking article, the flavoring-release additive comprising:
- gamma cyclodextrin having a ring structure that includes hydrophobic cavities;
- a flavoring incorporated within the hydrophobic cavities of the gamma cyclodextrin, the flavoring configured to undergo a controlled release from the hydrophobic cavities upon exposure of the flavoring-release additive to a first temperature, and the flavoring being present in an amount of at least 23% by weight of the flavoring-release additive;
- and
- an encapsulating material that at least partially encapsulates the gamma cyclodextrin.
