Hydrated ionic clay and tobacco material compositions
Compositions made from combinations including an hydrated ionic clay and a tobacco material are described herein. Methods of manufacture, as well as methods of extracting nicotine from these compositions are also described. The compositions can be used to prepare liquid vaporizable materials by extracting nicotine from tobacco material and directly from the tobacco material and into a liquid vaporizable material.
1 . A composition comprising:
a gel matrix comprising a hydrated ionic clay and a tobacco material; and
a solution comprising a solvent configured to extract nicotine from the tobacco material, wherein the gel matrix is immersed in the solution.
2 . The composition of claim 1 , wherein the hydrated ionic clay is between 1 wt % to 10 wt % of the gel matrix.
3 . The composition of claim 1 , wherein the tobacco material is between 20 wt % to 95 wt % of the gel matrix.
4 . The composition of claim 1 , wherein the hydrated ionic clay is a gel forming grade or a sol forming grade.
5 . The composition of claim 1 , wherein the hydrated ionic clay is Laponite.
6 . The composition of claim 1 , wherein the solution further comprises an organic acid, a flavoring agent, or both.
7 . The composition of claim 1 , wherein the tobacco material is a pure tobacco or a tobacco blend.
8 . The composition of claim 1 , wherein
the hydrated ionic clay is between 0.1 wt % to 5 wt % of the gel matrix, and
the tobacco material is between 20 wt % to 95 wt % of the gel matrix.
9 . The composition of claim 1 , wherein the tobacco material has a particle size distribution ranging from 50 to 5000 microns.
10 . The composition of claim 1 , wherein the gel matrix is formed as a pellet, brick, bead, tablet, plug, cylinder, or porous rod.
11 . The composition of claim 1 , wherein the gel matrix retains its shape within the solution.
12 . The composition of claim 1 , wherein the solution has a pH between 3 and 7.
13 . The composition of claim 1 , wherein a ratio of the tobacco material to the hydrated ionic clay is from 1:1 to 15:1.
14 . The composition of claim 1 , wherein 60% to 80% by mass of nicotine is released from the gel matrix into the solution.
15 . The composition of claim 1 , wherein the solvent comprises a humectant.
16 . The composition of claim 15 , wherein the humectant is vegetable glycerol, propylene glycol, or a combination thereof.
17 . The composition of claim 15 , wherein the solvent further comprises water.
18 . The composition of claim 17 , wherein the solution comprises propylene glycol, vegetable glycerol, and water at a ratio of 60:30:10.
19 . The composition of claim 16 , wherein a ratio of vegetable glycerol to propylene glycol is from 100:0 to 50:50.
20 . The composition of claim 16 , wherein a ratio of vegetable glycerol to propylene glycol is from 50:50 to 100:0.
