Embodiment 1

[0179] [Example 1] Evaluation of phenol selective filtration ability

[0180]

[0181] (Production of cigarette sample 1)

[0182] First, a paper filter with a length of 27 mm and a diameter of 7.7 mm was prepared. Specifically, first, paper (weight per unit area: 40 g / m 2 ) was bent or folded so as to form a plurality of air flow paths respectively extending from one end to the other end, and a rod having a length of 120 mm and a ventilation resistance of 400 mmAq was produced. This rod was cut to a length of 27 mm, and the thus obtained filter medium was wrapped in a paper tube having a length of 27 mm and a diameter of 7.7 mm as winding paper to produce a paper filter.

[0183] Next, 10 parts by mass of commercially available glyceryl monooleate (MGO: Glyceryl Monooleate) was supported on the filter material of the filter in an amount of 100 parts by mass. When loading glycerol monooleate, it was heated to 50° C. to make it fluidized, and then loaded so as to have a un...

Embodiment 2

[0214] [Example 2] Time-dependent stability evaluation of phenol selective filtration ability

[0215] In order to evaluate the stability of the phenol selective filtration ability over time, for cigarette sample 1, the phenol selective filtration index Sx after storage (sample number 1-2 or 1-3) was calculated relative to the immediately after production (sample number 1-1) The ratio of the phenol selection filtration index Sx [Sx (after storage) / Sx (before storage)]. The ratio [Sx (after storage) / Sx (before storage)] is an index for evaluating storage stability.

[0216] Similarly, the respective ratios [Sx (after storage) / Sx (before storage)] of cigarette samples 2 to 6 were calculated. These results are also shown in Table 4 above. It should be noted that for the cigarette sample 7 without adding phenol trapping agent, the value of Sx after storage and the value of Sx before storage basically did not change, so the ratio [Sx (after storage) / Sx (before storage) was not ca...

Embodiment 3

[0221] [Example 3] Leakage Evaluation of Phenol Scavenger

[0222]

[0223] (Production of filter sample A)

[0224] First, a paper filter with a length of 27 mm and a diameter of 7.7 mm was produced. Specifically, a corrugated paper was bent or folded so as to form a plurality of air flow paths extending from one end to the other end, and a rod with a length of 120 mm and a ventilation resistance of 400 mmAq was produced. This rod was cut to a length of 27 mm, and the thus obtained filter medium was wrapped in a paper tube having a length of 27 mm and a diameter of 7.7 mm as winding paper to produce a paper filter.

[0225] Next, this filter was erected on thick paper (Rengo Co.), and commercially available monoolein (MGO) heated to 50° C. and flowing was dripped onto the upper end surface of the filter using a microsyringe. The dropping amount was 10 parts by mass with respect to 100 parts by mass of filter media (excluding the paper tube). In addition, this dripping am...

Abstract

Provided is a member for a flavor inhalation article that has sufficient selective filtering performance with respect to phenols and has exceptional storage stability. This member for a flavor inhalation article includes: a base member; and a phenol scavenger supported by the base member, the phenol scavenger including a substance that satisfies formulas (1) to (3). (1) HSP(phenol) <= 8 (2) Vp <= 0.2 Pa (3) DP >= 50 DEG C In the formulas, HSP(phenol) is the distance between a Hansen solubility parameter pertaining to the substance and a Hansen solubility parameter pertaining to a phenol, Vp is the vapor pressure of the substance, and DP is the drop point of the substance.

Description

technical field [0001] The present invention relates to a member for scented inhalation articles, a scented inhalation article, a phenol trapping agent for scented inhalation articles, and a method for manufacturing a member for scented inhalation articles. Background technique [0002] Filters for flavored smoking articles such as cigarettes and non-combustible tobacco are required to reduce undesired components in mainstream smoke while maintaining flavor. As one of the methods for realizing this, it is known that a substance having a selective filtering ability for a specific component is loaded on a filter as an additive. As the additive leaks out of the filter, the filter's selective filtering ability for a particular ingredient is reduced. Therefore, such filters require storage stability, which refers to the property that the above-mentioned additives remain in the filter in an amount sufficient to maintain its selective filtering ability until the user takes a puff....
