A combustion retarding material and uses thereof

Abstract

A combustion retarding material including a combustion retarding salt and an amorphous solid material as well as consumables having the combustion retarding material, and non-combustible aerosol provision systems having such consumables. Methods for manufacturing the combustion retarding material and the use of a combustion retarding salt and an amorphous material to retard combustion.

1 . A material comprising a combustion retarding salt and an amorphous solid material. 
     
     
         2 . The material as claimed in  claim 1 , wherein the combustion retarding salt is an alkali metal salt, optionally selected from the group consisting of: sodium chloride, potassium chloride, sodium bromide, potassium bromide, and combinations thereof. 
     
     
         3 . The material as claimed in  claim 1 , wherein the combustion retarding salt is incorporated in the amorphous solid material. 
     
     
         4 . The material as claimed in  claim 1 , wherein the combustion retarding salt is applied to the amorphous solid material. 
     
     
         5 . The material as claimed in  claim 1 , wherein the material comprises from about 3 wt % to about 60 wt % combustion retarding salt (dry weight basis). 
     
     
         6 . A consumable comprising the material as claimed in  claim 1 . 
     
     
         7 . The consumable as claimed in  claim 6 , wherein the consumable further comprises an aerosol-generating material. 
     
     
         8 . The consumable as claimed in  claim 7 , wherein the material at least partially surrounds the aerosol-generating material. 
     
     
         9 . The consumable as claimed in  claim 6 , wherein the consumable further comprises a wrapper. 
     
     
         10 . The consumable as claimed in  claim 7 , wherein the material is distributed within the aerosol-generating material. 
     
     
         11 . The consumable as claimed in  claim 6 , wherein the aerosol-generating material comprises tobacco material. 
     
     
         12 . The consumable as claimed in  claim 11 , wherein the tobacco material is cut rag tobacco. 
     
     
         13 . The consumable as claimed in  claim 6 , wherein the consumable comprises a binder. 
     
     
         14 . The consumable as claimed in  claim 6 , wherein the consumable is rod shaped. 
     
     
         15 . The consumable as claimed in  claim 14 , wherein the rod has a distal and proximal end and wherein the material is provided exclusively or in greater concentration at a location proximal to the distal end of the rod. 
     
     
         16 . A non-combustible aerosol provision system comprising a consumable as claimed in  claim 6 . 
     
     
         17 . A method for manufacturing the material as claimed in  claim 1 , wherein the combustion retarding salt is incorporated into or added to the amorphous solid material. 
     
     
         18 . The method as claimed in  claim 17 , wherein a solution or suspension comprising the combustion retarding salt is applied to the amorphous solid material. 
     
     
         19 . The method as claimed in  claim 17 , wherein the combustion retarding salt is added during the manufacture of the amorphous solid material. 
     
     
         20 . Use of the material as claimed in  claim 1  for retarding combustion of a consumable for use in a non-combustible aerosol provision system.
