Composition for non-heating-type aerosol generating system including cooling agent and having improved amount of menthol transfer

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.

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.
