Non-combustion suction type tobacco product

Abstract

A non-combustion suction type tobacco product has tobacco particles made of tobacco material such as leaf tobacco, and at least one kind of stabilizer for stabilizing the delivery of nicotine from the tobacco particles, and the stabilizer has a characteristic where solubility parameter distance with respect to nicotine is 17 or less, and that vapor pressure at a temperature of 25 degrees centigrade is 1 mmHg or less.

1 . A non-combustion suction type tobacco product comprising tobacco particles obtained by shredding or pulverizing tobacco material, the tobacco product mixing nicotine specific to tobacco, which is generated from the tobacco particles, into suction air, and delivering the nicotine with the suction air into a user's mouth, wherein
 the tobacco particles further contains at least one kind of stabilizer for stabilizing the nicotine delivery to the user; and   said stabilizer has a characteristic where solubility parameter distance with respect to the nicotine is 17 or less, and vapor pressure at a temperature of 25 degrees centigrade is 1 mmHg or less.   
     
     
         2 . The non-combustion suction type tobacco product according to  claim 1 , wherein said stabilizer is selected from among compounds containing propylene glycol, benzyl alcohol or an ester group. 
     
     
         3 . The non-combustion suction type tobacco product according to  claim 2 , wherein said stabilizer is characterized in that the solubility parameter distance is 12 or less, and that the vapor pressure at a temperature of 25 degrees centigrade is 0.1 mmHg or less. 
     
     
         4 . The non-combustion suction type tobacco product according to  claim 2 , wherein said stabilizer is a compound containing the ester group. 
     
     
         5 . The non-combustion suction type tobacco product according to  claim 4 , wherein the compound is selected from among medium-chain triglyceride, triester citrate, benzyl benzoate, and ethyl laurate. 
     
     
         6 . The non-combustion suction type tobacco product according to  claim 5 , wherein the triester citrate is triethyl citrate or tributyl citrate. 
     
     
         7 . The non-combustion suction type tobacco product according to  claim 5 , wherein the tobacco particles further contain an additive having at least either one of carbonate and hydrogen carbonate. 
     
     
         8 . The non-combustion suction type tobacco product according to  claim 5 , further comprising a heat source for heating the tobacco particles to given temperature. 
     
     
         9 . The non-combustion suction type tobacco product according to  claim 1 , wherein said stabilizer has a content ranging from 5 to 20 percent by weight relative to dry weight of the tobacco particles. 
     
     
         10 . The non-combustion suction type tobacco product according to  claim 1 , wherein said stabilizer is characterized in that the solubility parameter distance is 12 or less, and that the vapor pressure at a temperature of 25 degrees centigrade is 0.1 mmHg or less.
