Description

Cooling block comprising cooling agents, and aerosol generating article comprising the same}

The present invention relates to cooling blocks comprising cooling agents, and aerosol-generating articles comprising the same.

Although some cooling agents have been used on their own in shaving foam, toothpaste, mouthwash, and food, there has been no case where a cooling block with flavored design technology of the cooling agent was used as a menthol replacement in aerosol-generating products.

Meanwhile, in current aerosol-generating products, menthol accounts for a higher proportion compared to other flavored substances, and competitiveness compared to existing menthol products can be secured only by providing key characteristics of menthol or differentiation and diversity compared to existing menthol products. It can be seen as a pending issue to develop menthol substitutes and secure product application technology to maintain the competitiveness of existing products and continue to provide benefits to consumers by implementing menthol-like characteristics.

Meanwhile, the sensory characteristics of menthol can be divided into main characteristics and auxiliary characteristics. The main characteristics are Cooling (refreshing feeling, body), Fresh (not dry), and Minty (minty flavor), and the auxiliary characteristics are Herbal and Green. , Earthy, etc.

In order to realize these complex sensory characteristics of menthol, the sole use of some specific cooling agents can be considered extremely limited, and menthol-like characteristics can only be realized through blending technology that reflects the characteristics of various cooling agents, so a recipe for this is possible.

Throughout the specification, 'aerosol-generating article' may refer to an article that can generate aerosol, and is used as a concept to include not only combustible aerosol-generating articles such as cigarettes, cigars, etc., but also non-heated aerosol-generating articles. . An aerosol-generating article may comprise an aerosol-generating material or an aerosol-forming substrate. Additionally, aerosol-generating articles may include solid materials (tobacco media) based on tobacco raw materials, such as leaf tobacco, cut tobacco, reconstituted tobacco, etc. Aerosol-generating substances may include volatile compounds.

Additionally, throughout the specification, 'upstream' or 'upstream direction' refers to a direction away from the mouth of the user smoking the aerosol-generating article, and 'downstream' or 'downstream direction' refers to a direction closer to the mouth of the user smoking the aerosol-generating article. It means the direction of falling. For example, in the combustion-type aerosol-generating article 100 shown in FIG. 1, the tobacco medium portion 120 is located upstream or in an upstream direction of the filter portion 110.

Furthermore, in this specification, the aerosol generating article 100 is limited to either a combustible cigarette or a non-combustible (heated) cigarette used with an aerosol generating device (not shown) such as an electronic cigarette device. However, it can include all of the above concepts.

In addition, as used herein, the cooling block may refer to a fragrance or coolant composition consisting of a combination of specific cooling agents developed herein to provide a refreshing feeling, cleanliness, and minty feeling, etc., which are characteristics of menthol. there is.

According to one embodiment of the present invention, 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; and

One or more cooling agents C selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineol and eucalyptol ;

It provides a cooling block for an aerosol-generating article, including a.

Cooling agent A included in the cooling block represents a base-type cooling agent with relatively low volatility that plays a role in giving body and sustainability to the scent. Cooling agent A Specific types include WS-3 (N-ethyl-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide), WS-5 (N-(ethoxycarbonylmethyl)-p-menthane-3-carboxamide), and WS-23. (N,2,3-trimethyl-2-isopropyl butanamide) and menthyl lactate, etc., and combinations thereof may be included as needed.

WS-3 has a long-lasting cooling sensation, and WS-5 has a similar cooling effect compared to WS-3, but off-flavors such as saltiness may appear. In addition, menthyl lactate can have the effect of providing a cooling sensation to a certain extent and the effect of maintaining its durability, and WS-23 can also provide a cooling sensation, but the degree of imparting may be lower than that of the menthyl lactate. Menthyl lactate can provide a cleaner or milder feel compared to WS-23.

In addition, when used together with WS-3, the menthyl lactate can neutralize the stinging taste of WS-3, and when judged comprehensively, to provide a cooling sensation, durability, cleanliness, and mild feeling, WS-3 It may be considered desirable to use a mixture of -3 and menthyl lactate.

Meanwhile, the content of the low-volatility base-type cooling agent A included in the cooling block according to an embodiment of the present invention may be 10% by weight to 60% by weight, and preferably 15% by weight to 55% by weight. , more preferably 20% by weight to 50% by weight.

If the content of cooling agent A exceeds the above upper limit, the overall harmony of the scent (cooling feeling, minty character, fresh, herbal harmony) may be broken, and the scent may become heavy, resulting in a middle-type cooling agent B. This may lead to negative results, such as suppressing the development of the scent of the top-type cooling agent C. If it is less than the above lower limit, the content of cooling agent A is insignificant, so the effect of providing a cooling sensation resulting from this is low, resulting in a harmonious taste. may fall.

In addition, the content of WS-3 that can be included in the cooling agent A may be 5% by weight to 20% by weight, and preferably 10% by weight to 15% by weight, based on the total weight of the cooling block. Additionally, the content of menthyl lactate may be 5% by weight to 40% by weight, more preferably 30% by weight to 40% by weight.

If the content of WS-3 and menthyl lactate falls within the above desirable range, as mentioned above, it may be the best in terms of overall cooling, durability, cleanliness, and mild feel, and according to this range, The difference in effect is also clearly visible through examples and comparative examples that will be described in detail later.

Cooling agent B included in the cooling block represents a middle-type cooling agent with medium volatility that plays a role in enhancing the character of the scent. Specific types of cooling agent B include , isopulegol, 4-terpineol, menthone, and menthyl acetate, and may also include a combination of these, if necessary.

Among the types of cooling agent B, menthone can give a minty feeling, and menthyl acetate has individual characteristics of the base type cooling agent A described above and the top type cooling agent C described later. It is responsible for harmoniously connecting the base, middle, and top notes as a whole so that they do not stand out too much. In addition, isopuregol can create an earthy feel, and 4-terpineol can enhance the harsh feel. However, isopuregol is an expensive ingredient, and the rough feeling of 4-terpineol can give smokers a negative feeling. Considering the purpose of the present invention to implement characteristics most similar to menthol, menthone and menthyl acetate may be considered preferable.

Meanwhile, the content of the medium-type cooling agent B with moderate volatility included in the cooling block according to an embodiment of the present invention may be 5% by weight to 50% by weight, and preferably 10% by weight to 45% by weight. %, more preferably 15% by weight to 40% by weight.

If the content of cooling agent B exceeds the above upper limit, the connection with the base-type cooling agent A and the top-type cooling agent C will be impaired, the harmony of the overall scent will be reduced, and the expression of the unique scent characteristics of the top-type cooling agent C will be limited. If it is less than the above lower limit, the content of cooling agent B is insignificant, so the minty character imparting effect resulting from this is low, and the aesthetics of harmony may be reduced.

In addition, the content of menthone that may be included 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. Additionally, the content of menthyl acetate may be 5% by weight to 20% by weight, and more preferably 2% by weight to 8% by weight.

When the content of menthone and menthyl acetate falls within the above preferred range, it can be seen that it is good in terms of scent intensity and harmony, as can be confirmed through comparison of Examples 1 to 2 and Comparative Example 2, which will be described later. Furthermore, it gives a minty feeling like menthol, and the top, middle, and base cooling agents combine to create effective harmony.

The cooling agent C included in the cooling block represents a highly volatile top-type cooling agent responsible for the intensity, unique characteristics, and dispersibility of the scent, and is a specific type of the cooling agent C. Examples include cis-3-hexenol, hexyl alcohol, 1,4-cineol, and eucalyptol, and the necessary Depending on this, combinations of these may also be included.

Among the types of cooling agent C, cis-3-hexenol can provide a green note like the smell of grass, and hexyl alcohol can provide an oily feeling in addition to the smell of grass. In addition, eucalyptol enhances minty characteristics and cooling effects and can impart natural, herbal, and fresh notes, while 1,4-cineole exhibits herbal, green, fresh, and light scent characteristics. It has the disadvantage of being less harmonious than eucalyptol. Therefore, in this respect, it is preferable to use eucalyptol as the cooling agent C.

Meanwhile, the content of the highly volatile tower-type cooling agent C included in the cooling block according to an embodiment of the present invention may be more than 0% by weight and less than 40% by weight, preferably 0.5% by weight to 10% by weight, Or it may be 0.5% by weight to 5% by weight.

If the content of the cooling agent C exceeds the above upper limit, the unique characteristics of the scent may not be realized naturally, an artificial and burdensome scent may occur, and the harmony with the middle-type cooling agent B may be broken. On the other hand, if cooling agent C is not included, the fragrance's unique characteristics may not be transmitted, so the perfection of the fragrance may be reduced, and the overall fresh and cheerful aspect may be lost.

These results can also be confirmed through a sensory evaluation comparison between Examples 1 and 2, which will be described later, and Comparative Example 3, which does not contain eucalyptol. Through this, it can be seen that the amount of cooling agent C contained in the cooling block is small. Despite this, it can be seen that menthol has a significant impact on refreshing sensation, enhancing aroma intensity, and refreshing aftertaste.

Meanwhile, the cooling block for aerosol-generating articles according to an embodiment of the present invention may additionally include a solvent for mixing the agents in addition to the cooling agent A, cooling agent B, and cooling agent C described in detail above, In this case, the solvent used may include one or more selected from the group consisting of alcohol, propylene glycol, and glycerol, and may preferably be alcohol.

At this time, the content of the solvent included 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.

In this way, by adjusting the amount of solvent contained in the cooling block, the harmony of cooling agents A, B, and C can be maintained as is, thereby maintaining their role as a menthol substitute, but only the scent intensity can be adjusted.

Meanwhile, according to another embodiment of the present invention, preparing cooling agent A, cooling agent B, and cooling agent C raw materials (S1); and

Mixing the cooling agent A, cooling agent B, and cooling agent C with a solvent (S2); Including,

The cooling agent A is at least one selected from the group consisting of WS-3, WS-5, WS-23 and menthyl lactate,

The cooling agent B is at least one selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate,

The cooling agent C is selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineol, and eucalyptol. A method of manufacturing a selected one or more cooling blocks for aerosol-generating articles may be provided.

At this time, the solvent that can be used is substantially the same as the type of solvent mentioned above, and is preferably alcohol.

The cooling block according to an embodiment of the present invention can be used for an aerosol-generating article, and the aerosol-generating article may correspond to a smoking article including a tobacco media portion, a filter portion, and a wrapper.

In this case, the cooling block may be included in one or more of the tobacco media part, filter part, and wrapper constituting the aerosol generating article, and may be flavored by spraying directly on the tobacco media part, filter part, and wrapper itself. (For example, TJNS; Transfer Jet Nozzle System), it can be used in the form of a capsule including a cooling block or included in a filter unit.

For example, when adding a cooling block to the tobacco medium of the tobacco medium unit, the amount of cooling block added may be 50 g to 250 g, preferably 100 g to 105 g, based on 100 kg of tobacco medium (cut filler). , if the amount of the cooling block is more or less than the above range, the effect of the cooling block intended in the present invention may be reduced.

In addition, the filter part included in the aerosol generating article may be divided into two or more segments and divided into a first filter part, a second filter part, etc., and regardless of the position where it is disposed, at least one of the two or more segments according to the present invention If it includes a cooling block according to an embodiment or a capsule containing it, it may be included in the scope of the present invention. Furthermore, the shape of the capsule may be spherical or cylindrical, but is not limited thereto.

In addition, the tobacco medium unit typically contains a tobacco material containing nicotine, such as leaf tobacco, and may additionally include excipients such as binders or other additives. As an example, the tobacco medium included in the tobacco medium unit of the present invention It can be manufactured in the form of granules containing tobacco substances and excipients.

In the present invention, the tobacco material is a material that constitutes the aerosol-forming substrate, and may be tobacco leaf pieces, tobacco stems, tobacco dust generated during tobacco processing, and/or leaf strips of tobacco leaves. The tobacco leaves may be at least one selected from yellow leaves, burley leaves, orient leaves, cigar leaves, and toast, but are not limited thereto.

Meanwhile, the wrapper according to an embodiment of the present invention may include a wrapper for each component of the aerosol-generating article, as shown in FIG. 1 (combustible aerosol-generating article), and may include a tobacco medium portion wrapper ( 120a), a filter wrapper (filter wrapper) 110a surrounding the filter, etc. In addition, as described above, when the filter unit is divided into a plurality of segments, a wrapper surrounding each segment may be included. In addition, in order to fix the connection between the tobacco medium unit and the filter unit, it may include a tipping wrapper 130 surrounding a portion of the tobacco medium unit and the filter unit, and to maintain the shape of the entire aerosol-generating article, etc. It may include an external wrapper located on the outermost side of the aerosol-generating article, surrounding both the and filter parts.

The tipping wrapper that combines the tobacco medium portion and the filter may optionally have one or more perforations formed along the circumferential direction to allow external air to flow in or internal gas to flow out, thereby increasing the air dilution rate of the cigarette. It has the effect of being able to control the amount of migration of mainstream smoke components.

Meanwhile, the cooling block according to an embodiment of the present invention may be included in a non-combustible heated aerosol generating article as shown in FIG. 2, and specific parts that may be included are substantially the same as those in FIG. 1 described above, such as the tobacco media part, filter part, and wrapper. It can be seen as similar.

Hereinafter, the configuration of the present invention and its effects will be described in more detail through examples and comparative examples. However, these examples are for illustrating the present invention in more detail, and the scope of the present invention is not limited to these examples.

(1) Manufacturing example: Manufacturing of cooling block

Example 1

To manufacture a cooling block according to an embodiment of the present invention, powdered WS-3 and menthyl lactate, and liquid menthone, menthyl acetate, and eucalyptol 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 to sufficiently dissolve them in the solvent, alcohol.

At this time, the contents of the added raw materials and alcohol were adjusted as shown in Table 1 below.

Example 2

A cooling block was manufactured in the same manner as in Example 1, except that the cooling agent content was adjusted to 25% by weight of WS-3 and 10% by weight of menthone and dissolved in alcohol.

Comparative Example 1

A cooling block was manufactured in the same manner as in Example 1, except that WS-23 was dissolved in alcohol instead of WS-3. At this time, the content of the added WS-23 was equal to the total weight of the manufactured cooling block. It was added to make it 15% by weight.

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. At this time, the content of the added 4-terpineol was was added to reach 20% by weight based on the total weight of the manufactured cooling block.

Comparative Example 3

A cooling block was prepared in the same manner as in Example 1, except that 1,4-cineol was dissolved in alcohol instead of eucalyptol. At this time, the added 1,4 -The content of cineole was added to be 2% by weight based on the total weight of the manufactured cooling block.

(2) Test Example 1: Sensory evaluation of the manufactured cooling block

After smoking the aerosol-generating articles containing the cooling blocks of Examples 1 to 2 and Comparative Examples 1 to 3 prepared previously, targeting 16 members of the KT&G R&D in-house panel, taste intensity, menthol refreshing sensation, throat smoothness, and aroma intensity were measured. , an evaluation was conducted based on a 9-point scale for harmony, clean aftertaste, and satisfaction. The average value of the evaluation results was calculated and shown in Table 2 below.

division Smelling strength Menthol refreshing feeling Soft on the throat Fragrance strength harmony Clean aftertaste satisfaction Example 1 4.23 5.03 4.54 5.17 5.24 5.22 5.14 Example 2 4.20 4.61 4.12 4.53 4.67 4.62 4.56 Comparative Example 1 3.54 4.54 4.08 4.51 4.52 4.02 4.08 Comparative example 2 4.14 4.58 4.53 3.58 4.06 4.53 4.13 Comparative Example 3 4.13 4.02 4.14 4.01 4.07 3.58 3.87

Referring to the results in Table 2 above, the evaluation results of Examples 1 and 2 containing all of WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol were lacking WS-3, menthone, and eucalyptol, respectively. Compared to Comparative Examples 1 to 3, it can be seen that better results are shown in terms of taste intensity, menthol refreshing sensation, aroma intensity, harmony, clean aftertaste, and overall satisfaction.

More specifically, in the case of Comparative Example 1 lacking WS-3, it can be seen that, among other items, the taste intensity and aftertaste cleanliness are worse, and in the case of Comparative Example 2 lacking menthone, the flavor intensity It can be seen that it is inferior in terms of harmony and beauty. In addition, it can be seen that Comparative Example 3, which lacks eucalyptol, is evaluated lower than the Examples in terms of menthol refreshing feeling, aroma intensity, harmony, and clean aftertaste.

In other words, it can be seen that the smoker's overall satisfaction with Examples 1 and 2 is superior to Comparative Examples 1 to 3.

On the other hand, when comparing Examples 1 and 2 in which the contents of WS-3 and menthone were adjusted differently, Example 2, in which an excessive amount of WS-3 was added or a small amount of menthone was added, had a lower menthol content than Example 1. There were slight differences in terms of refreshing sensation, smoothness of mouthfeel, aroma intensity, harmony, and clean aftertaste, resulting in slightly lower overall satisfaction.

(3) Test Example 2: Sensory evaluation comparison with current cigarettes
