Abstract
A method of preparing a nicotine and menthol sustained-release composition is provided. The method includes step S1 of melting menthol, step S2 of preparing a semi-solid dispersion by mixing the molten menthol, glycerin, and liquid nicotine, and step S3 of preparing a solid dispersion by adding at least one of lactose, microcrystalline cellulose (MCC), or cellulose to the semi-solid dispersion, wherein in step S2, the menthol is included in an amount of 25% by weight (wt %) to 58 wt % based on a total weight of the menthol and glycerin.
Claims15
A method of preparing a nicotine and menthol sustained-release composition, the method comprising:
- step S1 of melting menthol;
- step S2 of preparing a semi-solid dispersion by mixing the molten menthol, glycerin, and liquid nicotine;
- and
- step S3 of preparing a solid dispersion by adding at least one selected from a group consisting of lactose, microcrystalline cellulose (MCC), and cellulose to the semi-solid dispersion,
- wherein in step S2, the menthol is included in an amount of 25% by weight (wt %) to 58 wt % based on a total weight of the menthol and glycerin.
A nicotine and menthol sustained-release composition comprising:
- a solid dispersion comprising menthol, nicotine, and glycerin,
- wherein the solid dispersion is obtained by uniformly dispersing the menthol and the nicotine in the glycerin, and
- wherein the menthol is included in an amount of 25% by weight (wt %) to 58 wt % based on a total weight of the menthol and glycerin.
A tobacco-free smoking article comprising:
- a medium portion;
- and
- a filter portion,
- wherein the medium portion comprises a nicotine and menthol sustained-release composition,
- wherein the nicotine and menthol sustained-release composition comprises a solid dispersion comprising menthol, nicotine, and glycerin,
- wherein the solid dispersion is obtained by uniformly dispersing the menthol and the nicotine in the glycerin, and
- wherein the menthol is included in an amount of 25% by weight (wt %) to 58 wt % based on a total weight of the menthol and glycerin.
