  • Hydroxypropyl cellulose is a derivative of cellulose, and is a substance obtained by substituting the OH groups of cellulose with hydroxypropyl groups. Hydroxypropyl cellulose is widely used as a binder, a film-forming agent, and a gelling agent. Cellulose is a hydrophobic substance, since OH groups are hydrogen-bonded between molecules to crystallize. On the other hand, hydroxypropyl cellulose has hydroxypropyl groups, which make it difficult to form hydrogen bonds between molecules, and is therefore a substance having both hydrophilicity and hydrophobicity (i.e., an amphipathic substance).
  • hydroxypropyl cellulose forms a complex with a network structure through an interaction (hydrogen bond) between the hydroxypropyl groups of the hydroxypropyl cellulose and the OH groups of glycerin. Even when a flavorant other than glycerin is used, it is considered that hydroxypropyl cellulose can form a complex with a network structure through an interaction (hydrogen bond, a hydrophobic interaction, etc.) with the flavorant. Further, since hydroxypropyl cellulose has amphipathicity, it is considered that a hydrophilic flavorant and a hydrophobic flavorant can be incorporated into the network structure without using an emulsifier or the like.
  • such a complex with a network structure allows the flavorant to be stably carried without being volatilized during storage of the tobacco product, and to be stably released during the use of the tobacco product (in particular, during heating of the flavor inhalation article).
  • hydroxypropyl cellulose is soluble in an organic solvent, in particular, ethanol. Therefore, when the liquid composition containing hydroxypropyl cellulose, a flavorant, and a solvent is prepared as an ethanol solution, the viscosity of the ethanol solution can be made lower than that of an aqueous solution, which is advantageous over the aqueous solution in terms of transportation, coating, etc. in the manufacturing process.
  • the ethanol solution is dried to form a flavorant composition (e.g., a film of hydroxypropyl cellulose), the solvent vaporizes faster than in the case of the aqueous solution, which is advantageous in terms of reduction in manufacturing time and reduction in energy cost during drying.

  • flavorant component-containing particles specifically, ground leaf tobacco
  • a concentrated slurry liquid (viscosity: 409.5 [mPa ⁇ s]) consisting of 7.4% by weight of hydroxypropyl cellulose (Nippon Soda Co., Ltd.: CELNY SSL, which has a substitution degree of approximately 3.5 per glucose), 48.2% by weight of ethanol, 22.2% by weight of glycerin, and 22.2% by weight of ground leaf tobacco (particle diameter: 70-250 ⁇ m) was prepared.
  • a coating slurry liquid was prepared by diluting 10 g of the concentrated slurry liquid with 10 g of ethanol to adjust the viscosity to be suitable for coating on sheet tobacco.
  • a preparation liquid consisting of 64.0% by weight of ethanol, 20.0% by weight of glycerin, and 16.0% by weight of hydroxypropyl cellulose (Nippon Soda Co., Ltd.: CELNY SSL, which has a substitution degree of approximately 3.5 per glucose) was prepared.
  • the preparation liquid was applied to 0.626 g (15 cm ⁇ 11 cm) of cigarette paper (37 white) with a bar coater (pitch: 50 ⁇ m), and the cigarette paper was left at a room temperature of 22°C for 5 hours to volatilize ethanol. Thereby, the flavorant-carrying cigarette paper C was prepared.
  • the weight of the flavorant-carrying cigarette paper C was 1.143 g.
  • the flavorant-carrying cigarette paper C was cut into a size of 2.0 cm ⁇ 2.5 cm, and the flavorant-carrying cigarette paper C was bonded to a distal end portion of the heat-not-bum type flavor inhalation article 20 shown in FIG. 5 .
  • polyvinyl alcohol was used. Thereby, the flavor inhalation article C was prepared.
  • the flavor inhalation article C was heated by the heating device 10 shown in FIGS. 3 and 4 , and sample evaluation was performed.
  • a preparation liquid consisting of 50.0% by weight of ethanol and 50.0% by weight of glycerin was prepared.
  • 19 mg of the preparation liquid was equally injected into the tobacco-containing segment 20A (tobacco-containing segment: 250 mg) of the heat-not-burn type flavor inhalation article 20 shown in FIG. 5 using a microsyringe, and was left at a room temperature of 22°C for 5 hours to volatilize ethanol.
  • a flavor inhalation article D was prepared.
  • the flavor inhalation article D was heated by the heating device 10 shown in FIGS. 3 and 4 , and sample evaluation was performed.
  • the flavor inhalation article C and the flavor inhalation article D were coated with approximately 10 mg of glycerin per article, and were approximately equal in terms of the amount of coating of glycerin.
  • the two articles differ in that, in the flavor inhalation article C, glycerin was applied to the cigarette paper 22 located closer to the heating part, whereas, in the flavor inhalation article D, glycerin was applied to the tobacco filler 21 slightly distanced from the heating part. Therefore, it was confirmed that, when the flavor inhalation article C was inhaled, the amount of glycerin vapor was larger than that of the flavor inhalation article D. In addition, in the flavor inhalation article C, glycerin vapor was confirmed throughout the puff period.
  • a concentrated slurry liquid (viscosity: 691.5 [mPa ⁇ s]) consisting of 9% by weight of hydroxypropyl cellulose (Nippon Soda Co., Ltd.: CELNY SSL, which has a substitution degree of approximately 3.5 per glucose), 51% by weight of ethanol, 10% by weight of glycerin, and 30% by weight of ground leaf tobacco (particle diameter: 70-250 ⁇ m) was prepared. No precipitation of solid matter was observed in the concentrated slurry liquid even after being allowed to stand for 48 hours.
  • a coating slurry liquid was prepared by diluting 20 g of the concentrated slurry liquid with 20 g of ethanol to adjust the viscosity to be suitable for coating on a granular base material.
  • NONPAREIL 103 (Freund Corporation, particle diameter: 500 to 355 ⁇ m) was used as the granular base material.
  • 40 g of the coating slurry liquid was dropped onto 40 g of the granular base material while rolling the granular base material in a coating pan heated by applying hot air. During the dropping, ethanol in the coating slurry liquid was vaporized and removed. Thereby, a flavorant-carrying granular base material was prepared.
  • 310 mg of the flavorant-carrying granular base material was incorporated into the heat-not-bum type flavor inhalation article 30 shown in FIGS. 6 to 8 .
  • the flavorant-carrying granular base material can be prepared. Photographs of the prepared flavorant-carrying granular base material are shown in FIG. 13.

The photograph of the cut surface shows that the powder layer containing ground leaf tobacco was fixed to the surface of the granular base material.
  • a laminate of aluminum foil and paper (hereinafter referred to as "aluminum-laminated paper") was used.
  • the aluminum-laminated paper aluminum-bonded paper obtained by bonding aluminum foil to paper with an adhesive was used.
  • the slurry liquid was applied to a paper surface side of 0.672 g of the aluminum-laminated paper with a bar coater (OSG System Products Co., Ltd.: Wireless Bar Coater).
  • the slurry-coated aluminum-laminated paper was allowed to stand at a room temperature of 22°C to volatilize ethanol in the coating slurry liquid. Thereby, 1.222 g of flavorant-carrying aluminum-laminated paper was obtained.
