Cooling block including cooling agent and aerosol generating article including the same

Abstract

The present disclosure provides a cooling block for an aerosol generating article including a cooling agent A, a cooling agent B, and a cooling agent C in a specific combination, and an aerosol generating article including the same.

1 . A cooling block for an aerosol generating article, the cooling block comprising:
 at least one cooling agent A selected from a group consisting of WS-3, WS-5, WS-23, and menthyl lactate;   at least one cooling agent B selected from a group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate; and   at least one cooling agent C selected from a group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineol, and eucalyptol.   
     
     
         2 . The cooling block of  claim 1 , wherein the cooling agent A comprises WS-3 and mentyl lactate. 
     
     
         3 . The cooling block of  claim 2 , wherein the cooling agent B comprises menthone and menthyl acetate. 
     
     
         4 . The cooling block of  claim 3 , wherein the cooling agent C comprises eucalyptol. 
     
     
         5 . The cooling block of  claim 1 , comprising:
 with respect to a total weight of the cooling block,   the cooling agent A in an amount of 10 wt % to 60 wt %;   the cooling agent B in an amount of 5 wt % to 50 wt %; and   the cooling agent C in an amount of more than 0 wt % and 40 wt % or less.   
     
     
         6 . The cooling block of  claim 1 , comprising:
 a solvent, in addition to the cooling agent A, the cooling agent B, and the cooling agent C.   
     
     
         7 . The cooling block of  claim 6 , wherein
 the solvent comprises at least one selected from a group consisting of alcohol, propylene glycol, and glycerol, and   a content of the solvent is 50 wt % or less with respect to a total weight of the cooling block.   
     
     
         8 . The cooling block of  claim 1 , comprising:
 with respect to a total weight of the cooling block,   WS-3 in an amount of 10 wt % to 15 wt %;   menthyl lactate in an amount of 30 wt % to 40 wt %;   menthone in an amount of 15 wt % to 25 wt %;   menthyl acetate in an amount of 2 wt % to 8 wt;   eucalyptol in an amount of 0.5 wt % to 5 wt %; and   alcohol in an amount of 15 wt % to 30 wt %.   
     
     
         9 . A method of manufacturing a cooling block for an aerosol generating article, the method comprising:
 step S 1  of preparing raw materials for a cooling agent A, a cooling agent B, and a cooling agent C; and   step S 2  of mixing the cooling agent A, the cooling agent B, and the cooling agent C in a solvent,   wherein the cooling agent A is at least one selected from a group consisting of WS-3, WS-5, WS-23, and menthyl lactate,   wherein the cooling agent B is at least one selected from a group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate, and   wherein the cooling agent C is at least one selected from a group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineol, and eucalyptol.   
     
     
         10 . The method of  claim 9 , wherein the solvent comprises at least one selected from a group consisting of alcohol, propylene glycol, and glycerol. 
     
     
         11 . An aerosol generating article comprising:
 a tobacco medium portion;   a filter portion;   a wrapper; and   the cooling block of  claim 1 .   
     
     
         12 . The aerosol generating article of  claim 11 , wherein the aerosol generating article is a combustible or non-combustible heating type. 
     
     
         13 . (canceled)
