Abstract

Provided are a composition for an aerosol generating system, the composition including a humectant including propylene glycol (PG) and vegetable glycerin (VG), WS-3, and menthol, and a cartridge and an aerosol generating system including the same.

First claim

What is claimed is:

1 . A composition for an aerosol generating system, the composition comprising:
a humectant comprising propylene glycol (PG) and vegetable glycerin (VG); WS-3 (N-ethyl-5-methyl-2-(1-methylethyl) cyclohexanecarboxamide); and menthol.

2 . The composition of claim 1 , wherein a weight ratio of PG to VG in the humectant is 8:2 to 2:8.

3 . The composition of claim 1 , wherein a content of the WS-3 is 1.5 wt % or less based on the composition.

4 . The composition of claim 1 , wherein
a weight ratio of PG to VG in the humectant is 5:5, and a content of the WS-3 is 1.5 wt % or less based on the composition.

5 . The composition of claim 1 , wherein a content of the menthol is 10 to 15 wt % based on the composition.

6 . The composition of claim 1 , further comprising:
WS-23 (N,2,3-trimethyl-2-isopropyl butanamide).

7 . The composition of claim 6 , wherein a content of the WS-23 is more than 0 and 5 wt % or less based on the composition.

8 . The composition of claim 1 , wherein the aerosol generating system is a non-heated type or a low-temperature heated type of 0° C. to 150° C.

9 . A cartridge for an aerosol generating system comprising a liquid composition, wherein the liquid composition comprises a humectant comprising propylene glycol (PG) and vegetable glycerin (VG), WS-3 (N-ethyl-5-methyl-2-(1-methylethyl) cyclohexanecarboxamide), and menthol.

10 . An aerosol generating system comprising:
an aerosol generating article comprising a medium portion and at least one filter portion; and an aerosol generating device comprising a battery, a controller, and a vaporizer, wherein the medium portion comprises one or more of reconstituted tobacco, cut tobacco leaves and tobacco granules, a liquid composition is sprayed onto surfaces of one or more of the reconstituted tobacco, cut tobacco leaves and tobacco granules, and the liquid composition comprises a humectant comprising propylene glycol (PG) and vegetable glycerin (VG), WS-3 (N-ethyl-5-methyl-2-(1-methylethyl) cyclohexanecarboxamide), and menthol.

11 . The aerosol generating system of claim 10 , wherein
the aerosol generating device further comprises a cartridge, and the cartridge comprises the liquid composition.

12 . The aerosol generating system of claim 10 , wherein the liquid composition is sprayed onto the at least one filter portion.

13 . The aerosol generating system of claim 10 , wherein one or more of the reconstituted tobacco, cut tobacco leaves and tobacco granules are pH-treated to have a pH of 7.0 to 9.5.

14 . The aerosol generating system of claim 10 , wherein one or more of the reconstituted tobacco, cut tobacco leaves and tobacco granules generate volatile free nicotine under non-heated conditions or under low-temperature heated conditions of 0° C. to 150° C.
