Aerosol generation

Abstract

Disclosed herein is an aerosol generating material comprising an aerosol-forming layer, the aerosol-forming layer comprising an amorphous solid, wherein the aerosol-forming layer has a thickness of 0.015 mm to 1.0 mm.

1 . An aerosol generating material comprising an aerosol-forming layer, the aerosol-forming layer comprising an amorphous solid, wherein the aerosol-forming layer has a thickness of 0.015 mm to 1.0 mm. 
     
     
         2 . An aerosol generating material according to  claim 1 , further comprising a carrier on which the amorphous solid is provided. 
     
     
         3 . An aerosol generating material according to  claim 1 , wherein the amorphous solid comprises one or more of an active substance, an aerosol generating agent, a flavorant and a gelling agent. 
     
     
         4 . An aerosol generating material according to  claim 3 , wherein the material comprises a gelling agent selected from cross-linked pectin, cross-linked alginate and mixtures thereof. 
     
     
         5 . An aerosol generating material according to  claim 3 , wherein the material comprises an aerosol generating agent selected from erythritol, propylene glycol, glycerol and mixtures thereof. 
     
     
         6 . An aerosol generating assembly comprising an aerosol generating material according to  claim 1 , further comprising a heater configured to heat but not burn the aerosol generating material. 
     
     
         7 . An aerosol generating assembly according to  claim 6 , wherein the aerosol generating assembly is a heat-not-burn device. 
     
     
         8 . An aerosol generating assembly according to  claim 6 , wherein the aerosol generating assembly is an electronic tobacco hybrid device. 
     
     
         9 . An aerosol generating article for use in an aerosol generating assembly, the article comprising an aerosol generating material according to  claim 1 . 
     
     
         10 . A method of making an aerosol generating material according to  claim 1 . 
     
     
         11 . A method according to  claim 10 , the method comprising:
 (a) forming a slurry comprising components of the amorphous solid or precursors thereof,   (b) forming a layer of the slurry,   (c) setting the slurry to form a gel, and   (d) drying the gel to form an amorphous solid.   
     
     
         12 . A method according to  claim 11 , wherein the drying element causes the cast material thickness to reduce by at least 80%. 
     
     
         13 . A method according to  claim 11 , wherein (c) comprises the addition of a setting agent to the slurry.
