Abstract
Improved delivery of additives is provided through encapsulation. The encapsulated additives can be formed by encapsulating additives using co-ionic cross-linking, in-situ overcoating, and/or step-growth overcoating. By encapsulating additives, additives can be made heat and moisture stable and migration and/or loss of the additives within a cigarette, such as an activated carbon containing cigarette, can be reduced.
