Description

[Technical Field]

[0001] The present invention relates to scented sheets, filters, wrappers, and aerosol products containing the same, which contain cooling blocks. [Background technology]

[0002] Although some cooling agents have been used independently in shaving foam, toothpaste, mouthwash, and food products, there have been no cases where they have been used in aerosol products as a menthol substitute by utilizing a cooling block that incorporates the cooling agent's flavoring design technology.

[0003] Meanwhile, in current aerosol products, menthol accounts for a higher proportion than other flavoring substances, and only by adding the key characteristics of menthol and providing differentiation and diversity from existing menthols can a product be competitive with existing menthol products. Therefore, it is considered a pressing issue to develop menthol substitutes and secure product application technology so that the competitiveness of existing products can be maintained by realizing menthol-like characteristics and providing continuous benefits to consumers.

[0004] Meanwhile, the sensory characteristics of menthol can be divided into primary and secondary characteristics, with primary characteristics including cooling (refreshing feeling, body), freshness (clean feeling without dryness), and minty (minty aroma), while secondary characteristics include herbal, green, and earthy.

[0005] In order to realize such complex menthol sensory characteristics, it can be seen that the use of a specific cooling agent alone is extremely limited, and menthol-like characteristics can be realized only through blending technology that reflects the characteristics of various cooling agents, so it can be seen that recipe development for this is essential. Summary of the Invention [Problem to be solved by the invention]

[0019] In addition, in the description with reference to the accompanying drawings, the same components are denoted by the same reference numerals regardless of the drawing numerals, and redundant description thereof will be omitted. In describing the embodiments, if it is determined that a detailed description of related publicly known technology may unnecessarily obscure the gist of the embodiments, the detailed description thereof will be omitted.

[0020] Furthermore, when describing components of the embodiments, terms such as first, second, A, B, (a), (b), etc. are used to distinguish the components from other components, and the terms do not limit the essence, order, or sequence of the components.

[0021] Components having common functions to components included in any of the embodiments will be described using the same names in other embodiments. Unless otherwise specified, the description of one embodiment can be applied to other embodiments, and detailed description will be omitted to the extent that it overlaps.

[0022] Throughout the specification, the term "aerosol-producing article" can refer to anything that can generate an aerosol, and is used as a concept that includes not only combustion-type aerosol-producing articles such as tobacco (cigarettes) and cigars, but also non-combustion-heated aerosol-producing articles. The aerosol-producing article can include an aerosol-forming substance or an aerosol-forming substrate. The aerosol-producing article can also include a solid substance (tobacco medium) based on tobacco raw materials such as tabular tobacco, shredded tobacco, and reconstituted tobacco. The aerosol-forming substance can include a volatile compound.

[0023] Also, throughout the specification, "upstream" or "upstream direction" means a direction away from the mouth of a user smoking the aerosol product, and "downstream" or "downstream direction" means a direction toward the mouth of a user smoking the aerosol product. For example, in the combustion aerosol product 100 shown in Figure 1, the tobacco medium portion 120 is located upstream or in the upstream direction of the filter portion 110.

[0024] Furthermore, although the present specification uses examples of aerosol product 100 selected from the case of a combustion cigarette or a non-combustion (heated) cigarette used in conjunction with an aerosol generating device (not shown), such as an electronic cigarette device, the present specification is not limited to these examples and can include all of the above concepts.

[0025] In addition, in this specification, the term "cooling block" may refer to a flavor or cooling agent composition consisting of a combination of specific cooling agents developed in the present application to impart the refreshing, clean, minty, and other properties of menthol.

[0026] Furthermore, in this specification, the term "wrapper" refers to a material such as paper that wraps an aerosol product, and can be a concept that includes cigarette paper that wraps a tobacco medium portion, wrapping paper that wraps a filter, and a tipping wrapper that wraps both the tobacco medium portion and the filter.

[0027] According to one embodiment of the present invention, a method for manufacturing a cooling block is provided, comprising: The cooling block is one or more cooling agents A selected from the group consisting of WS-3, WS-5, WS-23 and menthyl lactate; one or more cooling agents B selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate; one or more cooling agents C selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineole, and eucalyptol; The present invention provides a scented sheet comprising:

[0028] According to another embodiment of the present invention, there is provided a filter for an aerosol product including a cooling block, the filter comprising: The cooling block is one or more cooling agents A selected from the group consisting of WS-3, WS-5, WS-23 and menthyl lactate; one or more cooling agents B selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate; one or more cooling agents C selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineole, and eucalyptol; The present invention provides a filter for an aerosol product, comprising:

[0029] Further, in accordance with one embodiment of the present invention, there is provided a wrapper for an aerosol product including a cooling block, the wrapper comprising: The cooling block is one or more cooling agents A selected from the group consisting of WS-3, WS-5, WS-23 and menthyl lactate; one or more cooling agents B selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate; one or more cooling agents C selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineole, and eucalyptol; The present invention provides a wrapper for an aerosol product, comprising:

[0030] The cooling agent A contained in the cooling block is a base-type cooling agent with relatively low volatility that is responsible for imparting body and longevity to the fragrance. Specific examples of the cooling agent A include WS-3 (N-ethyl-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide), WS-5 (N-(ethoxycarbonylmethyl)-p-menthane-3-carboxamide), WS-23 (N,2,3-trimethyl-2-isopropyl butanamide), and menthyl lactate, and combinations of these may also be included as needed.

[0031] WS-3 has good cooling sensation durability, and WS-5 has a similar cooling effect to WS-3, but may produce an unpleasant odor such as salty taste. Menthyl lactate can also provide a certain cooling sensation and maintain its durability, and WS-23 can also provide a cooling sensation, but the degree of cooling sensation may be less than that of menthyl lactate, and menthyl lactate can provide a cleaner or milder sensation than WS-23.

[0032] Furthermore, when used in combination with WS-3, the menthyl lactate can neutralize the harsh taste of WS-3. From a comprehensive perspective, it is preferable to use a mixture of WS-3 and menthyl lactate in order to provide a cooling sensation, lasting power, a refreshing sensation, a mild sensation, etc.

[0033] Meanwhile, the content of the low-volatility base-type cooling agent A contained in the cooling block according to one embodiment of the present invention may be 10 wt% to 60 wt%, preferably 15 wt% to 55 wt%, and more preferably 20 wt% to 50 wt%.

[0034] If the content of Cooling Agent A exceeds the upper limit, the overall harmonious flavor of the fragrance (cooling sensation, minty character, fresh, herbal harmony) may be lost, the fragrance may become heavy, and the expression of the middle-type Cooling Agent B and top-type Cooling Agent C may be suppressed, resulting in negative consequences. If the content of Cooling Agent A is less than the lower limit, the content of Cooling Agent A may be so small that the cooling sensation imparting effect is weak and the harmonious flavor may be reduced.

[0035] The content of WS-3 contained in the cooling agent A may be 5% to 20% by weight, preferably 10% to 15% by weight, based on the total weight of the cooling block, and the content of menthyl lactate may be 5% to 40% by weight, more preferably 30% to 40% by weight.

[0036] When the contents of WS-3 and menthyl lactate fall within the above-mentioned preferred ranges, the overall effects such as cooling sensation, lasting power, refreshing sensation, and mild sensation are the best, as mentioned above, and the difference in effects depending on the ranges will be clearly seen in the examples and comparative examples described in detail later.

[0037] The cooling agent B contained in the cooling block is a medium-type cooling agent with medium volatility that plays a role in enhancing the fragrance character. Specific examples of the cooling agent B include isopulegol, 4-terpineol, menthone, and menthyl acetate, and combinations thereof may also be included as needed.

[0038] Among the types of cooling agents B, menthone can impart a minty feeling, and menthyl acetate plays a role in harmoniously connecting the base, middle, and top notes so that the individual characteristics of the base-type cooling agent A described above and the top-type cooling agent C described below do not stand out too much. Furthermore, isopulegol exhibits an earthy feeling, and 4-terpineol can bring out a harsh feeling. However, since isopulegol is an expensive ingredient and the harsh feeling of 4-terpineol can cause negative impressions to smokers, considering the objective of the present invention to achieve properties most similar to menthol, the combination of menthone and menthyl acetate is considered to be preferable.

[0039] Meanwhile, the content of the middle-type cooling agent B having medium volatility contained in the cooling block according to one embodiment of the present invention may be 5 wt% to 50 wt%, preferably 10 wt% to 45 wt%, and more preferably 15 wt% to 40 wt%.

[0040] If the content of cooling agent B exceeds the upper limit, it may inhibit the combination with base-type cooling agent A and top-type cooling agent C, thereby reducing the overall harmonious flavor of the fragrance and limiting the expression of the unique fragrance characteristics of top-type cooling agent C. If the content of cooling agent B is below the lower limit, the content of cooling agent B is so small that the minty character-imparting effect is weak, and the harmonious flavor may be reduced.

[0041] Furthermore, the content of menthone contained in the cooling agent B may be 10% by weight to 30% by weight, and preferably 15% by weight to 25% by weight, based on the total weight of the cooling block. Also, the content of menthyl acetate may be 5% by weight to 20% by weight, and more preferably 2% by weight to 8% by weight.

[0042] When the contents of menthone and menthyl acetate are within the above-mentioned preferred ranges, as can be seen from the comparison between Examples 1 and 2 and Comparative Example 2 described below, it is found that the fragrance intensity and harmonious taste are good, and further, a minty feeling like menthol is imparted, and the characteristics of the top, middle and base type cooling agents are combined to effectively achieve harmony.

[0043] The cooling agent C contained in the cooling block is a highly volatile top-type cooling agent that is responsible for the strength, unique characteristics, and diffusibility of the fragrance. Specific examples of the cooling agent C include cis-3-hexenol, hexyl alcohol, 1,4-cineole, and eucalyptol, and combinations thereof may also be included as needed.

[0044] Among the cooling agents C, cis-3-hexenol can impart a grassy, ​​green note, while hexyl alcohol can impart an oily feel in addition to the grassy smell. Eucalyptol enhances the minty characteristics and cooling effect and can impart natural, herbal, and fresh notes. 1,4-cineole exhibits herbal, green, fresh, and light fragrance characteristics, but has the disadvantage of being less harmonious than eucalyptol. Therefore, it is preferable to use eucalyptol as the cooling agent C.

[0045] Meanwhile, the content of the highly volatile top-type cooling agent C contained in the cooling block according to one embodiment of the present invention may be more than 0 wt% and not more than 40 wt%, and preferably 0.5 wt% to 10 wt%, or 0.5 wt% to 5 wt%.

[0046] If the content of Cooling Agent C exceeds the upper limit, the fragrance's inherent characteristics will be artificial rather than natural, resulting in a heavy fragrance and a lack of harmony with the middle-type Cooling Agent B. On the other hand, if Cooling Agent C is not included, the fragrance's inherent characteristics will not be conveyed, resulting in a less complete fragrance and a loss of the overall freshness and lightness.

[0047] These results can also be confirmed through a comparison of sensory evaluation between Examples 1 and 2 described below and Comparative Example 3, which does not contain eucalyptol. This shows that Cooling Agent C has a significant effect on the refreshing feeling of menthol, the enhancement of fragrance strength, and the clean aftertaste, despite being contained in a small amount in the cooling block.

[0048] Meanwhile, the cooling block included in the scented sheet, filter for aerosol product, or wrapper according to one embodiment of the present invention may further include a solvent for mixing the agents in addition to the above-mentioned cooling agents A, B, and C. In this case, the solvent used may include one or more selected from the group consisting of alcohol, propylene glycol, and glycerol, and may be preferably alcohol.

[0049] In this case, the content of the solvent contained in the cooling block may be about 50% by weight or less, preferably about 15% to 30% by weight, based on the total weight of the cooling block.

[0050] In this way, by adjusting the amount of solvent contained in the cooling block, the harmonious taste of cooling agents A, B, and C can be maintained and their role as menthol substitutes can be maintained, but only the flavor intensity can be adjusted.

[0051] Meanwhile, the cooling block can be manufactured, for example, according to a method including the following steps.

[0052] Step S1 of preparing cooling agent A, cooling agent B, and cooling agent C raw materials; Step S2: mixing the cooling agent A, the cooling agent B, and the cooling agent C into a solvent.

[0053] In this case, the cooling agent A is one or more selected from the group consisting of WS-3, WS-5, WS-23, and menthyl lactate; the cooling agent B is one or more selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate; The cooling agent C can be one or more selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineole, and eucalyptol.

[0054] The solvent that can be used in step S2 is substantially the same as the solvent mentioned above, and is preferably alcohol.

[0055] To prepare the scented sheet according to one embodiment of the present invention, a slurry (or liquid preparation) containing distilled water, alcohol, a cellulose-based polymer, and the cooling block may be prepared, and the slurry may further contain a bulking agent and / or an emulsifier.

[0056] The distilled water is a factor that determines the viscosity of the slurry, and alcohol can be used as a solvent, an example of which is ethanol.

[0057] The cellulose-based polymer may include at least one selected from the group consisting of methyl cellulose (MC), ethyl cellulose (EC), carboxymethyl cellulose (CMC), carboxyethyl cellulose (CEC), hydroxymethyl cellulose (HMC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), hydroxypropyl methyl cellulose (HPMC), and hydroxyethyl methyl cellulose (HEMC). These types of cellulose-based polymers are easily soluble in alcohol solvents such as ethanol at room temperature.

[0058] The bulking agent serves to increase the total mass (i.e., dry mass) of the components other than water in the raw slurry, thereby increasing the volume of the scented sheet produced. The bulking agent only serves to increase the volume of the scented sheet, and has the property of not substantially increasing the viscosity of the raw slurry and not adversely affecting the cooling block-containing function of the scented sheet.

[0059] The bulking agent may preferably be a starch or a starch hydrolysate. Starch hydrolysate refers to a substance obtained by a process including a step of hydrolyzing starch. The starch hydrolysate may be, for example, a substance obtained by directly hydrolyzing starch (i.e., dextrin) or a substance obtained by hydrolyzing starch after heat treatment (i.e., fire-resistant dextrin). The bulking agent may be, for example, dextrin, more specifically, cyclodextrin.

[0060] On the other hand, a specific example of the emulsifier is lecithin.

[0061] A slurry containing the above-mentioned substances can be thinly spread to produce a sheet, which can then be dried to produce a scented sheet of a certain thickness.

[0062] Referring to Figure 3, it can be seen that the scented sheet before the final drying process has the same thickness as d1, and after the final drying process, it becomes even thinner and is produced with a thickness of d2. This difference is due to the difference in moisture content during drying, and the thickness of the scented sheet after drying can correspond to approximately 5 μm to 300 μm.

[0063] Furthermore, the drying step can be carried out at a temperature of about 40°C to 70°C.

[0064] Meanwhile, a filter for an aerosol product according to an embodiment of the present invention may be formed including a tow containing fiber bundles and a binder.

[0065] The fibers may include one or more selected from the group consisting of cellulose acetate (CA), lyocell, polypropylene (PP), and polylactic acid (PLA), and the binder may include one or more selected from the group consisting of hydroxypropyl methyl cellulose (HPMC), hydroxypropyl cellulose (HPC), polyvinyl alcohol (PVA), ethylene vinyl acetate (EVA), and polyvinyl acetate (PVAc).

[0066] The fibers correspond to a framework (support) that forms the filter portion, and the binder serves to connect a plurality of fiber bundles that form the framework and the tows that are formed by the bundles.

[0067] Furthermore, the filter according to an embodiment of the present invention may further include, in addition to the tow containing the fiber bundles and the binder, a plasticizer for improving the hardness of the filter, an emulsifier for preventing layer separation in the mixed solution during filter manufacturing, etc.

[0068] The plasticizer for improving hardness may be one or more of triethyl citrate (TEC) and triacetine (TA), and the emulsifier may be one or more of fatty acid carboxyl compounds, sorbitan ester compounds, sorbate compounds, and ethoxy compounds.

[0069] Meanwhile, the cooling block produced by the above-mentioned manufacturing method can be sprayed directly onto the wrapper of the aerosol product itself to be flavored (e.g., TJNS; Transfer Jet Nozzle System). In this case, the wrapper can be a sheet made of pulp or the like, specifically, a porous sheet having a thickness of about 5 μm to 150 μm, preferably 10 μm to 100 μm, and more preferably 10 μm to 50 μm, but is not limited thereto, and the thickness can vary depending on the role of the part where the wrapper is located.

[0070] For example, when the wrapper is used as cigarette paper to wrap the tobacco medium portion (shaved tobacco portion), it can have a thinner thickness than when used as a filter portion wrapper (filter paper) in order to prevent leakage of the contents of the portion wrapped by the cigarette paper and to ensure effective combustion while maintaining the shape of the aerosol product (smoking article).

[0071] Furthermore, the wrapper including the cooling block according to an embodiment of the present invention may contain at least one additive selected from the group consisting of a mineral filler and a burning chemical, in addition to the pulp and the cooling block, and may also contain a coating material made of a low-flammability material such as a low-flammability metal material.

[0072] The filler can increase whiteness and opacity, adjust porosity, improve texture and printability, and also reduce paper odor. Examples of fillers with such functions include calcium carbonate (CaCO3), magnesium oxide (MgO), and magnesium carbonate (MgCO3).

[0073] The combustion improver has the function of promoting or suppressing combustion, and examples thereof include ammonium phosphate, sodium citrate, and potassium citrate.

[0074] By simultaneously containing such a filler and a combustion improver, it is possible to ensure the smoking sensation, burning properties, extinguishing properties, and manufacturing workability of the cigarette.

[0075] The aroma-added sheet, filter, and wrapper including the cooling block according to one embodiment of the present invention can be used for aerosol products, and the aerosol products may be smoking articles including a tobacco medium portion, a filter portion, a wrapper, etc.

[0076] Existing methods of adding flavorings by directly spraying flavoring materials onto the tobacco medium, filter, wrapper, etc. (e.g., TJNS; Transfer Jet Nozzle System) have the disadvantage that when a large amount of flavoring is added, the amount of solvent required increases, causing stains on the target, such as the wrapper. However, when used as an aerosol product in sheet form, as in the present invention, these problems can be avoided, and a larger amount of flavoring can be added than with existing methods, which has the advantage of providing consumers with a greater smoking satisfaction.

[0077] The aromatizing sheet including the cooling block is located in the tobacco medium portion of the aerosol product, and can be mixed with the tobacco medium (cut grass) as shown in Figure 4. By including the aromatizing sheet in the tobacco medium portion together with the tobacco medium, it is possible to overcome the drawback of existing smoking articles in which the aroma weakens towards the latter half of smoking, and it has the advantage of enabling the cooling block to be continuously exerted during smoking.

[0078] The tobacco medium portion typically contains a tobacco substance containing nicotine, such as leaf tobacco, and may further contain excipients such as binders and other additives. For example, the tobacco medium contained in the tobacco medium portion of the present invention may be prepared in the form of granules containing a tobacco substance and excipients.

[0079] In the present invention, the tobacco material is a material constituting the aerosol-forming substrate, and may be tobacco leaf strips, tobacco stems, tobacco dust generated during tobacco processing, and / or tobacco leaf strips. The tobacco leaf may be at least one selected from the group consisting of flue-cured, burley, oriental, cigar, and toasted tobacco, but is not limited thereto.

[0080] Furthermore, when the scented sheet is located in the filter section, the filter section included in the aerosol product can be divided into two or more segments, such as a first filter section, a second filter section, etc., and therefore, regardless of the position where the scented sheet is located, it can be included in the scope of the present invention if one or more of the two or more segments includes a scented sheet according to an embodiment of the present invention. Therefore, the scented sheet can be located in various types of filter sections, and as an example, it can be located inside a paper tube filter.

[0081] Furthermore, if one of the two or more segments corresponds to a filter including a cooling block according to one embodiment of the present invention, it can be considered to be included in the scope of the present invention regardless of the location where it is placed.

[0082] That is, in the present application, the use of both a filter including a cooling block and a filter not including a cooling block is also included in the scope of the present invention.

[0083] On the other hand, a wrapper used as an aerosol product wraps components of a smoking article such as a tobacco medium section and / or a filter section, and a wrapper including a cooling block according to one embodiment of the present invention that wraps one or more of the tobacco medium section and the filter section can be considered to be within the scope of the present invention.

[0084] That is, in this application, the use of both a wrapper that includes a cooling block and a wrapper that does not include a cooling block is also included within the scope of the present invention.

[0085] Furthermore, when a flavoring sheet is added to the tobacco medium or filter, or a cooling block is added to the filter, the amount of the flavoring sheet or cooling block contained in the filter can be 50g to 250g, preferably 100g to 105g, per 100kg of tobacco medium (cut grass). If the amount of cooling block is more or less than the above range, the effect of the cooling block intended by the present invention may be reduced.

[0086] Meanwhile, as shown in Figure 1 (combustion aerosol product), a wrapper according to one embodiment of the present invention may include a wrapper for each component of the aerosol product, such as a tobacco medium wrapper 120a that wraps the tobacco medium section, a filter section wrapper (filter paper) 110a that wraps the filter, etc. In addition, as described above, if the filter section is divided into multiple segments, a wrapper for wrapping each segment may be included. Also, to secure the connection between the tobacco medium section and the filter section, a tipping wrapper 130 that wraps a portion of the tobacco medium section and the filter section may be included, and an outer wrapper 140 that is located at the outermost periphery of the aerosol product and wraps the tobacco medium section and filter section, etc., may be included to maintain the overall shape of the aerosol product.

[0087] The tipping wrapper, which connects the tobacco medium portion and the filter, may be selectively formed with one or more perforations along the circumferential direction to allow external air to flow in or internal gas to flow out, thereby achieving the air dilution rate of the cigarette and controlling the amount of mainstream smoke components transferred.

[0088] Meanwhile, the cooling block according to one embodiment of the present invention may also be included in a non-combustion heated aerosol product as shown in FIG. 2, and the specific parts included therein may be substantially similar to those shown in FIG. 1, such as the tobacco medium part, filter part, and wrapper.

[0089] According to yet another aspect of the present invention, there is provided a method of manufacturing a filter for an aerosol product including a cooling block, the method comprising the steps of: Step S1 of preparing a cooling block; Step S2: mixing one or more of a binder, a plasticizer, and an emulsifier with the cooling block to prepare a mixed solution; Step S3 of spraying the mixed solution onto a tow containing fiber bundles; The present invention provides a method for manufacturing a filter for an aerosol product, comprising:

[0090] According to yet another aspect of the present invention, there is provided a method of manufacturing a filter for an aerosol product including a cooling block, the method comprising the steps of: Step S1 of preparing a cooling block; Step S2: mixing one or more of a binder, a plasticizer, and an emulsifier with the cooling block to prepare a mixed solution; Step S3 of spraying the mixed solution onto a tow containing fiber bundles; The present invention provides a method for manufacturing a filter for an aerosol product, comprising:

[0091] The step S1 of manufacturing the cooling block can be considered to be substantially the same as the above-described method of manufacturing the cooling block, and the cooling block manufactured thereby is also the same as that described above.

[0092] The prepared cooling block may be mixed with one or more of a binder, a plasticizer, and an emulsifier and sprayed onto a tow containing fiber bundles, as described above, to be incorporated into a filter. Alternatively, a filter may be prepared through steps S2 and S3 excluding only the cooling block, and then the prepared cooling block may be separately sprayed onto the filter to be incorporated into the filter.

[0093] The spraying method is not particularly limited, but may be a method of directly spraying onto the tow or filter itself (e.g., TJNS; Transfer Jet Nozzle System), or may be sprayed in the form of a brush spray or electric spray.

[0094] This allows for the creation of a filter for an aerosol product including a cooling block according to one embodiment of the present invention.

[0095] The present invention will be described in more detail with reference to the following examples and comparative examples. However, the present invention is not limited to these examples, and the scope of the present invention is not limited to these examples.

[0096] [Example] (1) Manufacturing Example 1: Manufacturing of Cooling Block [Example 1] To manufacture a cooling block according to one embodiment of the present invention, WS-3 and menthyl lactate in powder form, and menthone, menthyl acetate, and eucalyptol in liquid form were prepared as fragrance raw materials. The prepared WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol raw materials were mixed and stirred for a certain period of time in alcohol, which was the solvent, to ensure they were sufficiently dissolved.

[0097] The amounts of the added raw materials and alcohol were adjusted as shown in Table 1 below.

[0098] [Example 2] A cooling block was manufactured in the same manner as in Example 1, except that the cooling agent contents were adjusted so that the WS-3 content was 25 wt % and the menthone content was 10 wt % and dissolved in alcohol.

[0099] [Comparative Example 1] A cooling block was prepared in the same manner as in Example 1, except that WS-23 was dissolved in alcohol instead of WS-3, and the amount of WS-23 added was 15 wt % based on the total weight of the prepared cooling block.

[0100] Comparative Example 2 A cooling block was prepared in the same manner as in Example 1, except that 4-terpineol was dissolved in alcohol instead of menthone, and the content of the 4-terpineol added was 20 wt % based on the total weight of the prepared cooling block.

[0101] Comparative Example 3 A cooling block was prepared in the same manner as in Example 1, except that 1,4-cineole was dissolved in alcohol instead of eucalyptol, and the content of the 1,4-cineole added was 2 wt % based on the total weight of the prepared cooling block.

[0102] The types and contents of the cooling agents contained in the cooling blocks manufactured in Examples 1 and 2 and Comparative Examples 1 to 3 are summarized in Table 1 below.

[0103] [Table 1]

[0104] (2) Manufacturing Example 2: Manufacturing of scented sheet containing cooling block Before preparing the scented sheet, the cooling block prepared in Example 1 above was first prepared, and distilled water, ethanol, methyl cellulose (MC), and cyclodextrin were mixed to prepare a scented sheet slurry with an appropriate viscosity.

[0105] The scented sheet slurry prepared above was thinly spread to form a sheet, and then dried at a temperature of 60°C to prepare the scented sheet containing a cooling block of the present invention having a uniform thickness and sheet shape.

[0106] (3) Test Example 1: Sensory evaluation of the manufactured cooling blocks Sixteen KT&G R&D in-house panelists smoked aerosol products containing the previously prepared cooling block-containing flavored sheets of Examples 1-2 and Comparative Examples 1-3 in the tobacco medium, and then evaluated the smoking taste strength, refreshing menthol feeling, smooth throat feel, flavor strength, harmonious taste, clean aftertaste, and satisfaction level on a scale of 1 to 9. The average values ​​of the evaluation results were calculated and are shown in Table 2 below.

[0107] [Table 2]

[0108] Referring to the results in Table 2 above, it can be seen that the evaluation results of Examples 1 and 2, which contain all of WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol, show better results in terms of smoking taste intensity, refreshing menthol feeling, fragrance intensity, harmonious taste, clean aftertaste, and overall satisfaction, compared to Comparative Examples 1 to 3, which lack WS-3, menthone, or eucalyptol, respectively.

[0109] More specifically, Comparative Example 1 lacking WS-3 was found to be inferior in terms of smoking intensity and clean aftertaste, among other items, while Comparative Example 2 lacking menthone was found to be inferior in terms of flavor intensity and harmonious flavor.Furthermore, Comparative Example 3 lacking eucalyptol was found to be rated lower than the Examples in terms of menthol refreshing flavor, flavor intensity, harmonious flavor, and clean aftertaste.

[0110] That is, this makes it possible to understand that the overall satisfaction level of Examples 1 and 2 is superior to that of Comparative Examples 1 to 3 among smokers.

[0111] On the other hand, when Examples 1 and 2 in which the contents of WS-3 and menthone were adjusted differently were compared, Example 2 in which an excessive amount of WS-3 was added or a small amount of menthone was added showed slight differences compared to Example 1 in terms of menthol refreshing feeling, smoothness in the throat, strength of fragrance, harmonious taste and clean aftertaste, and also showed slightly inferior results in terms of overall satisfaction.

[0112] (4) Test Example 2: Sensory Evaluation Comparison with Current Cigarettes [Comparison of the aerosol product containing the scented sheet of Manufacturing Example 2 with the current ESSE CHANGE 1mg] The scented sheet containing the cooling block prepared in Preparation Example 2 was applied to an aerosol product.

[0113] Then, 13 members of KT&G R&D's in-house panel smoked the current ESSE CHANGE 1mg (a prototype product in which menthol was mixed with the secondary flavoring agent when making ESSE CHANGE 1mg) and the aerosol product containing the cooling block of Example 1, and then evaluated the smoking strength, refreshing menthol feeling, smoothness aftertaste, flavor strength, harmonious taste, clean aftertaste, and satisfaction level on a scale of 1 to 9. The average values ​​of the evaluation results were calculated and are shown in Table 3 below.

[0114] [Table 3]

[0115] [Comparison of the aerosol product containing the scented sheet of Manufacturing Example 2 with the general ESSE CHANGE 1mg] Sixteen members of KT&G R&D's in-house panel smoked both ESSE CHANGE 1mg (a prototype product in which menthol and cooling block were not mixed in the secondary flavoring) and the aerosol product containing the scented sheet containing cooling block of Preparation Example 2, and then evaluated using the same method as above. The average values ​​of the evaluation results were calculated and are shown in Table 4 below.

[0116] [Table 4]

[0117] [Comparison of the aerosol product containing the cooling block of Manufacturing Example 2 with the current RAISON FRENCH BLACK] Sixteen members of the KT&G R&D in-house panel inhaled the aerosol products containing the current RAISON FRENCH BLACK and the scented sheet containing the cooling block of Preparation Example 2, and then conducted the same evaluation as above. The average values ​​of the evaluation results were calculated and are shown in Table 5 below.

[0118] [Table 5]

[0119] From the results of Test Example 2, it can be seen that the aerosol product containing the scented sheet containing the cooling block according to one embodiment of the present invention tends to exhibit a higher level of menthol refreshing sensation, clean aftertaste, and overall satisfaction compared to aerosol products such as ESSE CHANGE 1mg current, ESSE CHANGE 1mg regular, and RAISON FRENCH BLACK, and it can be seen that the cooling block complements the taste acceptance and satisfaction of existing menthol products or can effectively realize the main sensory characteristics.

[0120] As described above, although the embodiments have been described with limited drawings, those skilled in the art can apply various technical modifications and variations based on the above. For example, the described techniques may be performed in an order different from that described, and / or the components of the described systems, structures, devices, circuits, etc. may be combined or combined in a form different from that described, or may be substituted or replaced by other components or equivalents, and still achieve suitable results.
