First Claim
Patent Images
1. A composition capable of progressively releasing flavor in smoking articles upon contact with moisture-containing smoke comprising an admixture of:
- a selected soluble flavoring material;
a solvent for said flavoring material;
a moisture releasing hydrophilic polymer; and
an amount of triacetin effective to retain the flavoring material in the composition.

24. A method for making a flavor-releasing smoking article comprising the steps of:
-
a. admixing a soluble flavoring material with a solvent; b. adding triacetin to the mixture of step (a); c. admixing the mixture of step (b) at a slow rate with a moisture releasing hydrophilic polymer; d. applying the final mixture of step (c) to a smoking article where it will be exposed to moisture containing smoke; and e. providing a source of moisture-containing smoke capable of causing said mixture to progressively release said flavoring material. - View Dependent Claims (25, 26, 27, 28, 29, 30)
