  • Tobacco sensation cigarette-like was evaluated as "a somatic sensation including a cigarette-like flavor and irritation.”
  • the maximum number of evaluations per day was 5, and additive-free lots were also evaluated for each evaluation day.
  • the evaluation was made by starting smoking 30 seconds after the start of heating, then smoking at intervals of 30 seconds, and smoking was possible for up to 5 minutes. In order to perform a stable evaluation, it was excluded from the evaluation target for 2 minutes from the start of heating.
  • the median number of particles that can be measured by DMS is an index for the generated aerosol particles to exist stably without volatilizing until they are delivered to the user's oral cavity.
  • the diameter (Count Median Diameter) was used. Since the DMS measures the aerosol under reduced pressure (0.25 bar) and high dilution conditions, the highly volatile aerosol easily disappears and is gasified. In the case of an aerosol having relatively low volatility, although the aerosol shrinks due to volatilization, a particle size distribution can be obtained as a residual aerosol.
  • the particle size distribution of the residual aerosol differs depending on the amount of volatility.
  • the peak particle size based on the number indicates stability under reduced pressure and high dilution conditions, and was used as an index. The larger the central diameter of the number of particles, the more stable the aerosol exists, and the smaller the central diameter of the number of particles, the more unstable the aerosol.
  • the primary dilution was performed at 25 L / min and the secondary dilution was performed at a setting of 200 times.
  • Spraytec (Model STP5321, Mulvern) is used to measure the mass peak particle size immediately after the occurrence before dilution or decompression, and there is no difference in the type of additive and the range of the amount added in this example. There was a median diameter of the number of particles in the vicinity of about 200 nm.
  • Table 2 shows the test results.
  • FIG. 5 shows the solubility with glycerin and the effect of tobacco sensation on each single fatty acid
  • FIG. 6 shows the tobacco sensation when palmitic acid, which is a saturated fatty acid of C16, and oleic acid as a mixture are added.
  • palmitic acid which is a saturated fatty acid of C16
  • oleic acid as a mixture
  • the highest tobacco sensation can be obtained when palmitic acid, which is a saturated fatty acid of C16
  • stearic acid which is a saturated fatty acid of C18
  • unsaturated fatty acids have a relatively high solubility in glycerin, it was clarified that even if they are C18, their effects are lower than those of saturated fatty acids. Although the effect was confirmed on the saturated fatty acid of C19, the amount of C19 is very small as a naturally occurring amount, and there is a manufacturing problem when using it. Therefore, it is considered that a high tobacco sensation can be obtained by adding saturated fatty acids corresponding to C16 to C18.
  • palmitic acid which is an unsaturated fatty acid
  • palmitic acid which is a saturated fatty acid of C16
