Description

PLASTICIZER FOR IMPROVED BIO-DEGRADABILITY, FILTER, AND SMOKING ARTICLE INCLUDING THE SAME

More particularly, it relates to a natural plasticizer capable of improving the biodegradability of a filter, a filter manufactured using the same, and a smoking article including the same.

When tobacco filters are manufactured from tows, which are bundles of fiber strands, plasticizers are added during the manufacturing process. The plasticizer can improve the hardness of the tow by partially dissolving (plasticizing) the fibers constituting the tow and forming multiple bonds between the fibers. The added plasticizer may vary depending on the type of tow (or fiber). An artificial plasticizer such as triacetin is usually added to cellulose acetate tow mainly used in cigarette filters.

However, a cellulose acetate filter (or tow) to which an artificial plasticizer is added is not biodegradable and may cause various environmental problems. For example, cigarette butts disposed of in the sewer may block drainage and cause flooding during the rainy season.

In order to prevent such environmental problems, it is more important to improve the biodegradability of the cellulose acetate filter.

A technical problem to be solved through some embodiments of the present disclosure is to provide a natural plasticizer capable of improving the biodegradability of a filter by replacing the existing artificial plasticizer.

natural plasticizer

Cellulose acetate filters are filters mainly used in smoking articles, and are manufactured based on cellulose acetate tow, and a plasticizer is added to the tow during the filter manufacturing process. The plasticizer added to the cellulose acetate tow is an artificial plasticizer such as triacetin (hereinafter, “TA”) and triethyl citrate (hereinafter, “TEC”).

However, there has always been a concern that the cellulose acetate filter manufactured with such a plasticizer does not biodegrade well, causing environmental problems. Therefore, the inventors of the present disclosure have continuously conducted research to develop a new plasticizer that can improve the biodegradability of cellulose acetate filters as an alternative to artificial plasticizers such as TA or TEC.

As a result of the study, surprisingly, the present inventors were able to confirm that the material extracted from the clove plant had the property of dissolving (plasticizing) cellulose acetate tow.

1 and 2 are enlarged views of a portion of the cellulose acetate tow 1 to which the clove extract is added. Specifically, Figure 1 shows a portion of the cellulose acetate tow (1) enlarged by about 50 times, and Figure 2 is shown at about 200 times magnification of the plasticization portion (2) in the cellulose acetate tow (1). .

1 and 2, when the clove extract is added to the cellulose acetate tow, it can be confirmed that the fiber constituting the tow is melted (plasticization phenomenon).

Hereinafter, through various experimental examples, the plasticizing effect and performance of the clove extract are to be made clearer.

Experimental Example 1: Comparative experiment on plasticizing effect

Experimental Example 1 was performed to clarify that the plasticization phenomenon of cellulose acetate tow was attributed to the clove extract. In this experimental example, two experiments were performed as follows. The first experiment ("Experimental Example 1-1") was performed with water and general hyangaek as a comparison target, and the second experiment ("Experimental Example 1-2") was It was performed by comparing the existing plasticizers TA and TEC.

Experimental Example 1-1: Comparative experiment with water and general perfume

In Experimental Example 1-1, the cellulose acetate tow was mixed with water, a general perfume solution, and a clove extract solution, respectively, and the plasticization state of the cellulose acetate tow was compared. The general hyangaek is a general hyangaek that can be used in smoking articles, and in this experimental example, a fruit flavoring combination fragrance was used, but other fragrances may be used. The results according to this experimental example are shown in FIG. 3 .

3, the beaker 11 on the left shows the mixed state of water and cellulose acetate tow, the beaker 12 in the middle shows the mixed state of the clove extract and the cellulose acetate tow, and the beaker 13 on the right shows the general hyangaek and The mixed state of the cellulose acetate tow is shown.

Referring to FIG. 3 , it can be seen that, while the cellulose acetate tow maintains its shape in water and general perfume (see 11 and 13), it is plasticized in the clove extract solution (see 12). Therefore, it can be confirmed that the clove extract has the property of imparting plasticity to the cellulose acetate tow.

Experimental Example 1-2: Comparative test with TA and TEC

Experimental Example 1-2 was performed for two purposes. The first purpose is to confirm whether the clove extract can replace TA and TEC, which are artificial plasticizers, and the second purpose is to determine whether the plasticizer performance of the clove extract can be adjusted according to the concentration. is to check

In order to achieve the above object, in this experimental example, an experiment was performed in which cellulose acetate tow was mixed with each of a concentrated clove extract solution, a diluted clove extract solution, TA and TEC, and then an experiment was performed to compare the plasticization state of the cellulose acetate tow. . In this experimental example, a solution of about 50% concentration was used as the concentrated clove extract solution, and a solution of about 25% concentration was used as the diluted clove extract solution. The experimental results for this are shown in FIG. 4 .

In FIG. 4, the first beaker 21 on the left shows a mixed state of TA and cellulose acetate tow, the second beaker 22 shows a mixed state of TEC and cellulose acetate tow, and the third beaker 23 is a concentrated clove extract solution and It shows the mixed state of the cellulose acetate tow. In addition, the last beaker 24 shows the mixed state of the diluted clove extract solution and cellulose acetate tow.

4, it can be seen that the concentrated clove extract plasticizes cellulose acetate tow to a level similar to TEC (see 22, 23), and the diluted clove extract plasticizes cellulose acetate tow to a level similar to TA. It can be seen that (see 21, 24). Therefore, it can be confirmed from this that the plasticizing performance of the clove extract is sufficiently excellent to replace the artificial plasticizer.

In addition, it can be confirmed that the cellulose acetate tow is more plasticized in the concentrated clove extract than the diluted clove extract. It can be confirmed that the plasticizing performance of the extract can be controlled.

Experimental Example 2: Comparative experiment for each component

Experimental Example 2 was performed to determine which component of the clove extract caused the plasticization of cellulose acetate tow or to determine which component of the clove extract was more closely related to the plasticization phenomenon. Since the clove extract is a mixture including a plurality of components, the effect on the plasticization of tow may be different for each component. For the main components of the clove extract, refer to Table 1 below.

No. ingredient One beta-caryophyllene 2 Methyl-benzoate 3 Caryophyllene oxide 4 eugenol 5 eugenyl acetate 6 alpha-humulene 7 Humulene oxide 8 1-alpha-cadinol ... ...

In this experimental example, the effect of each component of Table 1 on the cellulose acetate tow was tested. As a result of the experiment, it was confirmed that beta-caryophyllene, methyl-benzoic acid, caryophyllene oxide, eugenol and eugenyl acetate components had a greater effect on the plasticization of cellulose acetate tow than other components. Additional experiments were performed to compare the plasticizing performance of phyllene, methyl-benzoic acid, caryophyllene oxide, eugenol and eugenyl acetate components, and the experimental results are shown in FIG. 5 .

5 shows a state in which each of the solutions of the five components is mixed with cellulose acetate tow, and the abbreviations "B-CP", "E", "MB", " CO" and "EA" refer to the components beta-caryophyllene, eugenol, methyl-benzoic acid, caryophyllene oxide and eugenyl acetate, respectively.

Referring to FIG. 5 , it can be seen that the degree of plasticization of the cellulose acetate tow is shown in the order of caryophyllene oxide, methyl-benzoic acid, beta-caryophyllene, eugenol, and eugenyl acetate. Therefore, it may be desirable to use caryophyllene oxide and methyl-benzoic acid as the main components of the plasticizer. However, if it is desired to enhance the clove flavor of a smoking article by adding the clove scent to the cellulose acetate filter, it may be preferable to use eugenol or eugenyl acetate as a main component of the plasticizer.

Figure 6 shows the degree of curing of the plasticized cellulose acetate tow shown in Figure 5.

Referring to FIG. 6 , it can be seen that the curing phenomenon appears in all of the cellulose acetate tows 41 to 45 to which beta-caryophyllene, eugenol, methyl-benzoic acid, caryophyllene oxide and eugenyl acetate are added.

Table 2 below is a measure of the degree of curing of the cellulose acetate tows 41 to 45 shown in FIG. 6 for each component. The degree of curing in Table 2 below is expressed as a percentage (%) of the change resistance of the tow, and may be calculated by Equation 1 below. In Equation 1 below, W means the thickness (eg diameter) of the tow (ie, the tow in an uncompressed state) before the load F is applied, and W _F is the tow (ie, the pressed tow) after the load is applied. It means the thickness of the tow). According to Equation 1 below, the harder the tow (that is, the smaller the degree of pressing), the closer the degree of curing may be closer to 100%.

The degree of hardening in Table 2 below was calculated by measuring the thickness of the cellulose acetate tow before and after compression by receiving a total load of about 2 kg for a time of about 20 seconds. For this measurement, a known density meter device may be used, but the curing degree measurement method may be measured in another method.

In addition, referring to Table 2 below, it can be seen that the degree of curing of the cellulose acetate tows 41 to 45 is similar to each other. However, since the cellulose acetate tows 44 and 43 to which caryophyllene oxide and methyl benzoic acid are added are relatively hardened, it is better to use caryophyllene oxide and methyl benzoic acid as the main components of the plasticizer when manufacturing a cellulose acetate filter. may be desirable.

In addition, the degree of curing of the cellulose acetate tows 41 to 45 is all 80% or more, which corresponds to a degree similar to the case in which TA or TEC is added. Accordingly, it can be seen that each component of Table 2 below can be used for commercial purposes together with artificial plasticizers such as TA or TEC.

ingredient Hardening degree (%) Beta-caryophyllene 84 eugenol 83 methyl benzoic acid 86 Caryophyllene Oxide 87 eugenyl acetate 81

Table 3 below shows beta-caryophyllene, eugenol, methyl-benzoic acid, caryophyllene oxide and eugenyl acetate components, when added together with TA, the degree of curing of the cellulose acetate tow was measured for each component. Specifically, when TA (100%) was added alone and when TA (50%) and the above components (50%) were added together (addition amount was the same), the degree of tow curing was measured. The degree of curing was measured in the same manner as in Table 2. As shown in Table 3 below, even when components such as TA and beta-caryophyllene were added together (that is, some of the added amount of TA was replaced with a component of the clove extract) Even), it can be seen that almost the same plasticizing performance as TA is shown.

ingredient Hardening degree (%) TA 95 Beta-caryophyllene + TA 93 Eugenol + TA 92 Methyl benzoic acid + TA 94 Caryophyllene Oxide+TA 94 Eugenyl Acetate+TA 93

Various experimental examples regarding the clove extract have been described so far. As described above, it was clearly confirmed that the clove extract, a natural material extracted from the clove plant, can be used as a plasticizer for cellulose acetate tow. In addition, it was clearly confirmed that the plasticizing performance of clove extract was good enough to replace conventional artificial plasticizers such as TA and TEC. In addition, among the various components included in the clove extract, it was confirmed that beta-caryophyllene, methyl-benzoic acid, caryophyllene oxide, eugenol and eugenyl acetate components were closely related to the plasticizer phenomenon of cellulose acetate tow. Based on the above, some examples of natural plasticizers will be described.

natural plasticizer (a)

The natural plasticizer (a) may be composed of at least some of the components included in the clove extract. For example, the natural plasticizer (a) may include at least one of beta-caryophyllene, methyl-benzoic acid, caryophyllene oxide, eugenol and eugenyl acetate components.

The natural plasticizer (a) may be applied to the cellulose acetate tow, but the subject matter of application is not limited thereto. The natural plasticizer (a) may be added to the cellulose acetate tow during the filter manufacturing process to produce a cellulose acetate filter.

natural plasticizer (b)

The natural plasticizer (b) may be composed of components not related to the clove scent among a plurality of components included in the clove extract. For example, the natural plasticizer (b) may include a component of at least some of beta-caryophyllene, methyl-benzoic acid and caryophyllene oxide.

The natural plasticizer (b) may be applied to the cellulose acetate tow, but the subject matter of application is not limited thereto. The natural plasticizer (b) may be added to the cellulose acetate tow during the filter manufacturing process to produce a cellulose acetate filter.

The cellulose acetate filter prepared through the natural plasticizer (b) can be universally applied to various smoking articles. For example, the cellulose acetate filter may be applied to a clove-scented smoking article and may also be applied to a non-clove-scented smoking article.

natural plasticizer (c)

The natural plasticizer (c) may be composed of a component related to clove flavor among a plurality of components included in the clove extract. For example, the natural plasticizer (c) may include a component of at least a portion of eugenol and eugenyl acetate.

The natural plasticizer (c) may be applied to the cellulose acetate tow, but the subject matter of application is not limited thereto. A natural plasticizer (c) may be added to the cellulose acetate tow during the filter manufacturing process to produce a cellulose acetate filter.

In some embodiments, a cellulose acetate filter made through a natural plasticizer (c) can be applied to a clove flavored smoking article (e.g. Cretec tobacco). In this case, the amount of eugenol transferred during smoking may be further increased, so that the clove flavor and flavor of the smoking article may be enhanced.

In some other embodiments, the cellulose acetate filter may be applied to non-clove-scented smoking articles. When the clove material is added to smoking articles in the form of a flavoring agent, the clove scent is transmitted strongly, which may have a negative effect on smokers who are not familiar with the clove scent. In this case, the present embodiment may be considered so that the clove scent can be transmitted subtly through the cellulose acetate filter to which the clove extract is added instead of the flavor granules.

Cellulose Acetate Filter

A cellulose acetate filter can be manufactured using the aforementioned natural plasticizers. The cellulose acetate filter may be used as a filter for a smoking article, but the scope of application is not limited thereto.

The cellulose acetate filter may be manufactured through a filter manufacturing process well known in the art. Those skilled in the art will be able to clearly understand the filter manufacturing process, so the description of the filter manufacturing process itself will be omitted.

In some embodiments, porous flavor granules containing clove extract may be added to the cellulose acetate filter. The reason why the clove extract is added in the form of porous granules is that the solidified granules having a porous structure are very effective in suppressing the volatility of the clove extract. It may be desirable that the flavor granules have a diameter of about 0.4 mm or more. This is because when very fine flavor granules are added to the filter material, dust may be generated in the filter or the flavor granules may be adsorbed to the filter, which may affect the filter's performance. because there is In addition, it may be desirable that the diameter of the flavor granules 23 be less than about 1.4 mm, because as the diameter of the flavor granules 23 increases, the resistance to aspiration increases, which may negatively affect the smoker's comfortable smoking experience. . According to this embodiment, since the transfer amount of eugenol is maximized through the flavor granules, the clove flavor and flavor of the smoking article can be greatly improved. In addition, since the porous flavor granules suppress the volatility of the clove extract, the clove flavor and flavor of the smoking article can be maintained over time.

The cellulose acetate filter may consist of a single filter or multiple filters. As such, the detailed structure of the cellulose acetate filter may be variously modified or designed according to embodiments, so the technical scope of the present disclosure is not limited by a specific filter structure.

On the other hand, in some other embodiments of the present disclosure, a cellulose acetate filter may be manufactured by appropriately mixing an artificial plasticizer (e.g. TA, TEC) and a material suitably blended with the aforementioned natural plasticizer. The artificial plasticizer may have better overall plasticizing performance than the natural plasticizer, but the biodegradability of the manufactured filter may be significantly lower than that of the natural plasticizer. Accordingly, the mixing ratio of the two plasticizers may be appropriately determined in consideration of the plasticizing performance and the biodegradability of the filter, and preferably, the content of the natural plasticizer may be 10% to 70% or 15% to 65%. More preferably, the content of the natural plasticizer may be 20% to 60%, 20% to 50%, 30% to 50%, 35% to 50% or 45% to 50%.

Experimental Example 3: Comparative experiment on biodegradability of cellulose acetate tow (filter)

Experimental Example 3 was performed to determine the effect of the clove extract on the biodegradability of the filter. Specifically, a cellulose acetate filter was prepared by adding clove extract components (beta-caryophyllene, eugenol, methyl-benzoic acid, caryophyllene oxide and eugenyl acetate) and TA as a plasticizer, and then, the prepared filter was subjected to a relative temperature of 22°C. It was stored for 7 days in a solvent (water) at a humidity of 60%, and the weight before and after storage was measured. The measurement results are shown in Table 4 below.

For reference, when manufacturing a cellulose acetate filter, TA (50%) and clove extract component (50%) were mixed and added (see Table 4), which is for process reasons.

ingredient Weight (mg) weight difference before biodegradation after biodegradation Difference (mg) Difference(%) TA 941 905 36 3.8 Beta-caryophyllene + TA 1,327 1,235 92 6.9 Eugenol + TA 1,607 1,434 173 10.8 Methyl benzoic acid + TA 1,435 1,342 93 6.5 Caryophyllene Oxide+TA 1521 1,435 86 5.7 Eugenyl Acetate+TA 1,637 1,458 179 10.9

Referring to Table 4 above, it can be seen that the filter to which the clove extract and TA are added is approximately twice as likely to biodegrade as compared to the filter to which TA is added alone. This means that the clove extract can greatly enhance the biodegradability of the filter. In particular, it can be seen that the filter to which TA and eugenol or eugenyl acetate are added is biodegradable approximately 3 times, which is This means that eugenol and eugenol acetate are more effective in enhancing the biodegradability of filters.

In addition, the experimental results in Table 4 indicate that even if the clove extract is added as a plasticizer together with TA, there is a biodegradability enhancing effect, and if the clove extract is added alone, it is determined that the biodegradability of the filter will be further improved.

smoking articles

Smoking articles can be made using the cellulose acetate filters mentioned above. The smoking article may include a clove-scented smoking article (A) and a non-clove-scented smoking article (B).

Smoking article (A)

Smoking article (A) is a clove-scented smoking article (e.g. Cretec tobacco), an exemplary structure of which is shown in FIG. 7 . However, since the structure shown in FIG. 7 is only an example for providing convenience of understanding, the technical scope of the present disclosure is not limited thereto.

As shown in FIG. 7 , the smoking article 50 may include a filter portion 51 and a smoking material portion 52 . However, only components related to the embodiment of the present disclosure are illustrated in FIG. 7 . Accordingly, those of ordinary skill in the art to which the present disclosure pertains can know that other general-purpose components other than those shown in FIG. 7 may be further included.

The filter unit 51 may include a cellulose acetate filter and a filter wrapper for wrapping it, and may be connected to at least one of both ends of the smoking material unit 52 . For example, the filter unit 51 and the smoking material unit 52 may have a cylindrical shape and are aligned in the longitudinal axis direction, and the filter unit 51 may be located downstream of the smoking material unit 52 . Also, the filter unit 51 and the smoking material unit 52 may be connected by a tipping wrapper. The tipping wrapper may connect at least a portion of the filter unit 51 and at least a portion of the smoking material unit 52 together to connect the filter unit 51 and the smoking material unit 52 . When the filter part 51 is located at the downstream end of the smoking article 50 , the filter part 51 may also serve as a mouthpiece.

The filter unit 51 may be formed of a single filter or multiple filters. In addition, the filter unit 51 may include a cavity formed by multiple filters, and a capsule containing a flavor material may be located inside the filter unit 51 (e.g. cavity). As such, the detailed configuration or implementation form of the filter unit 51 may be modified according to embodiments, and thus the technical scope of the present disclosure is not limited by the detailed configuration or implementation form of the filter unit 51 .

In some embodiments, the filter unit 51 may include a cellulose acetate filter manufactured through a natural plasticizer (c) (e.g. eugenol, eugenyl acetate). In this case, the amount of eugenol transferred during smoking may be increased to further enhance the clove flavor and flavor of the smoking article 50 .

Next, the smoking material unit 52 may include a smoking material and a wrapper that wraps the smoking material. The smoking material part 52 may have a cylindrical shape, but the technical scope of the present disclosure is not limited thereto.

The smoking material may include various types of materials that generate smoke and/or aerosols or are used for smoking. The smoker generates smoke and/or aerosol through the smoking article 50 , and the generated smoke and/or aerosol may be inhaled by the smoker through the filter unit 51 .

The smoking material may include, for example, tobacco material. Tobacco material may include, for example, tobacco leaf pieces, tobacco stems or materials processed therefrom, and the like. As a more specific example, the tobacco material may include pulverized tobacco leaves, pulverized reconstituted tobacco, expanded cornflower, expanded stems and leaflets, and the like.

In some embodiments, the smoking material may further include additives such as wetting agents, flavoring agents and/or organic acids. For example, the wetting agent may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Wetting agents can keep moisture in the tobacco material at an appropriate level, softening its intrinsic taste, and enriching the amount of atomization. In addition, flavoring agents include, for example, licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil. , vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander, clove extract (or clove substance) or coffee can do.

In some embodiments, the smoking material may comprise a clove material. For example, the clove material may include clove powder, clove plant fragments, etc. produced by grinding or processing clove plants (e.g. clove leaves). In such a case, since a crackling sound (or kritek-critek) is generated during smoking, an auditory effect is added to the clove taste and flavor, thereby providing a smoker with an improved smoking experience. .

Also, in some embodiments, polysaccharide materials (eg, cellulose, starch, glycogen, etc.) may be added to the smoking material portion 52 to enhance the sound generating effect of the smoking article 50 . The surprising fact that a polysaccharide material generates sound when it is burned was revealed during the course of continuous research. Through experiments, the present inventors confirmed that a certain sound is generated as the crystal structure is broken when the polysaccharide material is burned. Accordingly, according to the present embodiment, the polysaccharide material added to the smoking material part 52 acts as a sound generating factor during smoking, so that the sound generating effect of the smoking article 50 may be increased.

In the above-described embodiment, the polysaccharide material may be added in place of the clove material, or may be added together with the clove material. The polysaccharide material may be processed into, for example, particles, sheets, and elongated objects (e.g. toothpick shapes) and added to the smoking material portion 52, but the technical scope of the present disclosure is not limited thereto. . As a more specific example, the polysaccharide material in the form of particles may be added to the smoking material portion 52 or a wrapper that wraps the smoking material. As another example, the polysaccharide material in the form of a sheet may be added to the smoking material portion 52 together with the tobacco sheet or disposed on the wrapper. As another example, the polysaccharide material in the form of an elongated object may be added to the smoking material portion 52 in a engraved or uncut state. According to the present embodiment, the sound generation effect of the smoking article 50 is increased, so that a more improved smoking experience can be provided to the smoker. Furthermore, since polysaccharide materials (e.g. starch) are generally very inexpensive, the material cost of the smoking article 50 can be reduced. Furthermore, since the polysaccharide material (e.g. starch) is a safe material that humans ingest as food, the safety of the smoking article 50 is ensured and the cost of the safety test can be reduced.

In addition, according to various embodiments of the present disclosure, a clove extract (e.g. clove oil) including a eugenol component may be added to the smoking article 50 as a flavoring agent to add clove flavor and flavor. At this time, in order to improve the flavor preservation of the clove extract, a flavoring agent may be added to the smoking article 50 in the form of solidified porous granules, and the location at which the flavor granules are added depends on the diameter of the flavor granules, the detailed structure of the smoking article, and the like. may vary based on factors.

For example, as described above, the flavor granules may be added to the cellulose acetate filter constituting the filter unit 51 .

As another example, the filter unit 51 includes a cavity (not shown) formed between multiple filters, and the flavor granules may be added to the cavity. By doing so, the addition of flavor granules can be prevented from affecting the filter performance. In addition, by adding the flavor granules to be densely packed inside the cavity, the flavoring effect of the flavor granules may be enhanced.

As another example, the flavor granules may be added to the smoking material unit 52 instead of the filter unit 51 . By doing so, it can be prevented that flavor granules affect filter performance, and the amount of eugenol transfer can be greatly increased. The diameter of the flavor granules added to the smoking material part 52 may be, for example, about 0.8 mm or less, and preferably about 0.6 mm or about 0.5 mm or less. More preferably, the diameter of the flavor granules may be less than or equal to about 0.4 mm or about 0.3 mm, as an increase in the size of the flavor granules may increase resistance to suction or negatively affect the burning rate of the smoking material.

As another example, the flavor granules may be added to at least one wrapper included in the smoking article 50 . The wrapper may include, but is not limited to, for example, a tipping wrapper, a filter wrapper, a wrapper of the smoking material portion 52, and the like. In this case, the clove flavor and flavor of the smoking article 50 may be enhanced without affecting the suction resistance or filter performance of the smoking article 50 .

Smoking article (B)

The smoking article B (not shown) is a smoking article that does not have a clove scent, and may have a structure similar to that of the smoking article 50 illustrated in FIG. 7 . However, since there is no clove scent, the smoking article (B) does not contain a clove material.

The filter part of the smoking article (B) may include a cellulose acetate filter made through a natural plasticizer (b). In this case, the biodegradability of the filter is improved, and environmental problems caused by the artificial plasticizer can be prevented in advance.

In some other embodiments, the filter portion of the smoking article (B) may include a cellulose acetate filter made through a natural plasticizer (c). In this case, the clove scent may be subtly expressed during smoking.

Although embodiments of the present disclosure have been described with reference to the accompanying drawings, those of ordinary skill in the art to which the present disclosure pertains may practice the present disclosure in other specific forms without changing the technical spirit or essential features. can understand that there is Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
