Description

FIELD

The present disclosure relates to a composition for smokeless tobacco and orally dissolvable film-type smokeless tobacco containing the same. More specifically, the present disclosure relates to a composition for orally dissolvable film-type smokeless tobacco, which is capable of improving an intraoral intake rate of nicotine, moldability, and acceptability while lowering harmfulness to a human body, orally dissolvable film-type smokeless tobacco containing the same, and a method for manufacturing the same.

DESCRIPTION OF RELATED ART

A development of smokeless tobacco is becoming more active as a seriousness of a damage caused by secondhand smoking is widely known and because of changes in a social environment of reducing smoking places. However, traditional smokeless tobacco, such as wet snuff and the like, is considered wet and dirty, so that use of the traditional smokeless tobacco is negative.

Accordingly, recently, as a kind of the smokeless tobacco, products in a mesh structure, a film form, or a sheet form that may dissolve in a user's mouth to release nicotine have been developed.

However, the conventional smokeless tobacco contains a number of substances, such as tar in addition to the nicotine, harmful to a human body with a main component of tobacco particles, and is not completely dissolved, so that precipitate remains. In addition, in a manufacture of the conventional smokeless tobacco, a high temperature treatment process at a temperature equal to or higher than 100° C. had to be undergone to dissolve the tobacco particles. Furthermore, the conventional smokeless tobacco contains a tobacco component in a high dose, which causes a very bitter taste and a low acceptability. In addition, the conventional smokeless tobacco is formed by being molded into a laminated body shape or by extruding a non-aqueous composition or melting the non-aqueous composition at a high temperature, so that a manufacturing process is complicated, a process cost is increased, and a productivity is low.

In one example, in general, an oral dissolving film (ODF) refers to a formulation that is taken by being attached to an oral cavity, such as a top face of a tongue, oral mucosa, a bottom face of the tongue, and the like, and being dissolved, which is a concept that includes an edible film in which a raw material, such as starch, that is not harmful to the human body and is well soluble in water and a substance that is beneficial to the human body are mixed with each other. Such oral dissolving film has an advantage of being able to be taken without the water and being convenient to carry.

The edible film is manufactured by adding a plasticizer, an emulsifier, a sweeting agent, an acidulant, a flavor, and other additives to a base of a water-soluble polymer, such as pullulan, sodium alginate, pectin, gelatin, carrageenan, xanthan gum, locust bean gum, and the like.

The conventional oral dissolving film is stored by coating a liquid edible raw material on a base film paper, then drying the base film paper, and then rolling the base film paper. Alternatively, the conventional oral dissolving film is manufactured by transporting the rolled base film paper to a packaging machine, then slitting the base film paper, then cutting the base film paper into a size considering a film surface area, and then inserting each cut base film paper into each packaging material to be packaged and sealed. Therefore, the conventional oral dissolving film is unreasonable in that there are a large number of manufacturing processes and a semi-finished product stock is generated as being stored in the roll shape. Thus, the conventional oral dissolving film has a problem that additional hygiene management is required as well as a cost is increased due to productivity decrease and stock burden.

As a background technology of the present disclosure, Korean Patent Application Publication No. 10-2012-0087937 discloses a wet smokeless tobacco product for oral use having a gel coating of a net structure and a method for manufacturing the same.

Throughout the present disclosure, a number of patent documents are referenced and citations thereof are indicated. An entirety of the disclosed content of the cited patent document is inserted as a reference in the present disclosure, so that the level of the technical field to which the present disclosure belongs and the content of the present disclosure are more clearly described.

Composition for Smokeless Tobacco

According to an embodiment, a composition for smokeless tobacco contains a nicotine activator of 0.01 to 4 parts by weight; a binder of 40 to 80 parts by weight; and a plasticizer of 2 to 10 parts by weight.

The composition for the smokeless tobacco contains the nicotine activator in a low dose to reduce harmfulness to a human body, and at the same time, improve acceptability and intraoral disintegration degree of film-type smokeless tobacco.

The nicotine activator is a main component of the composition for the smokeless tobacco, which may be nicotine or a nicotine derivative. The nicotine derivative may be a nicotine salt (tartaric acid, citric acid, and the like) or a nicotine complex. The nicotine activator is nicotine oil, which may be suitable to have a purity equal to or higher than 99%, but is not limited thereto. Because the composition for the smokeless tobacco does not contain tobacco particles, components, such as tar and the like, harmful to the human body are excluded, thereby reducing the harmfulness of the smokeless tobacco to the human body.

The nicotine activator may be contained in 0.01 to 4 parts by weight based on a solid weight of the composition for the smokeless tobacco. Although not limited thereto, when the nicotine activator of less than 0.01 parts by weight is contained based on the solid weight of the composition for the smokeless tobacco, it is difficult to meet needs of a user who needs the nicotine. Further, when the nicotine activator is contained in excess of 4 parts by weight, a very bitter taste may be produced, the acceptability may be reduced, and intraoral disintegration time may be lengthened. The harmfulness to the human body may be reduced by containing the nicotine activator in a low dose. In addition, even when the nicotine activator is contained in the low dose, an absorption rate of the nicotine may become relatively high compared to a high dose because of a reaction of the body for maintaining a nicotine content in a blood at a level equal to or above a certain level.

The nicotine activator may be contained, based on the solid weight of the composition for the smokeless tobacco, in 0.01 to 4 parts by weight, in 0.01 to 3.5 parts by weight, in 0.01 to 2.5 parts by weight, in 0.01 to 1.0 parts by weight, in 0.01 to 0.5 parts by weight, in 0.05 to 4 parts by weight, in 0.05 to 3.5 parts by weight, in 0.05 to 2.5 parts by weight, in 0.05 to 1.0 parts by weight, in 0.05 to 0.5 parts by weight, in 0.1 to 4 parts by weight, in 0.1 to 3.5 parts by weight, in 0.1 to 2.5 parts by weight, in 0.1 to 1.0 parts by weight, and in 0.1 to 0.5 parts by weight. The content of the nicotine activator may be suitably 0.01 to 2.5 parts by weight, more suitably 0.01 to 1.0 parts by weight, and even more suitably 0.01 to 0.5 parts by weight, but may not be limited thereto.

The binder is decomposed by saliva in an oral cavity to release the nicotine into the oral cavity, and allows the nicotine activator to be molded in a film form. The binder may be hydroxypropylmethylcellulose or hydroxypropylcellulose. The hydroxypropylmethylcellulose may be suitable in terms of moldability, the acceptability, and the intraoral disintegration time when the smokeless tobacco is manufactured as the film, but the present disclosure may not be limited thereto. Therefore, because the composition for the smokeless tobacco does not contain a metharylic acid ethyl acrylate copolymer, problems of lowering of the acceptability and prolonged intraoral disintegration time resulted from the metharylic acid ethyl acrylate may be solved. In addition, unlike in the prior art, the smokeless tobacco may be rapidly disintegrated in the oral cavity even though the smokeless tobacco does not contain an alkaline buffer.

The binder may be contained in 40 to 80 parts by weight based on the solid weight of the composition for the smokeless tobacco. When the binder is contained in less than 40 parts by weight of the composition for the smokeless tobacco, the moldability may be rapidly deteriorated when the smokeless tobacco is manufactured as the film. In addition, when the binder is contained in excess of 80 parts by weight, the moldability, the acceptability, and the intraoral disintegration degree may be deteriorated when the smokeless tobacco is manufactured as the film, but the present disclosure may not be limited thereto. The binder may be contained, based on the solid weight of the composition for the smokeless tobacco, in 40 to 80 parts by weight, in 40 to 70 parts by weight, in 40 to 60 parts by weight, in 40 to 50 parts by weight, in 50 to 80 parts by weight, in 50 to 70 parts by weight, in 50 to 60 parts by weight, in 60 to 80 parts by weight, and in 60 to 70 parts by weight. The content of the binder may be suitably 40 to 70 parts by weight, and more suitably 40 to 60 parts by weight, but may not be limited thereto.

At least one type of the plasticizer may be contained in the composition for the smokeless tobacco. The plasticizer may include glycerin, propylene glycol, ethylene glycol, polyethylene glycol, sorbitol, xylitol, maltitol, erythritol, tributhyl citrate, triethyl citrate, triacetin, and glycerol triacetate, but may not be limited thereto.

The plasticizer may be contained in 2 to 10 parts by weight based on the solid weight of the composition for the smokeless tobacco. When the plasticizer is contained in less than 2 parts by weight based on the solid weight of the composition for the smokeless tobacco, the moldability may be rapidly deteriorated when the smokeless tobacco is manufactured as the film. In addition, when the plasticizer is contained in excess of 10 parts by weight, the moldability, the acceptability, and the intraoral disintegration degree may be deteriorated when the smokeless tobacco is manufactured as the film, but the present disclosure may not be limited thereto. The plasticizer may be contained, based on the solid weight of the composition for the smokeless tobacco, in 2 to 10 parts by weight, in 2 to 7 parts by weight, in 2 to 5 parts by weight, or in 2 to 3 parts by weight. The content of the plasticizer may be suitably 2 to 7 parts by weight, and more suitably 2 to 5 parts by weight, but may not be limited thereto.

The composition for the smokeless tobacco may contain water as a solvent. Using the water as the solvent instead of an organic solvent such as ethanol and the like may be suitable in terms of the moldability, the acceptability, and the shortening of the disintegration time when the smokeless tobacco is manufactured as the film. Purified water may be used as the water, and may be contained in 180 to 250 parts by weight based on 100 parts by weight of a solid content, but the present disclosure may not be limited thereto.

The composition for the smokeless tobacco may have a viscosity of 15,000±5,000 cps. When the viscosity of the composition for the smokeless tobacco is out of the above range, the moldability may be lowered when the smokeless tobacco is manufactured as the film, but the present disclosure may not be limited thereto.

The composition for the smokeless tobacco may further contain at least one of a flavor, a surfactant, a sweeting agent, and a coloring agent. These components may improve the acceptability and the moldability of the smokeless tobacco.

The flavor may improve the acceptability of the smokeless tobacco as a flavoring agent. Although not limited thereto, the flavor may include natural and artificial flavors, and may include, for example, peppermint, spearmint, winter green, menthol, cinnamon, chocolate, vanillin, licorice, clove, anise, sandalwood, geranium, rose oil, vanilla, lemon oil, cassia, fennel, ginger, ethyl acetate, isoamyl acetate, propyl isobutylate, isobutyl butyrate, ethyl butyrate, ethyl valerate, benzyl formate, limonene, cymene, pinene, linalol, geraniol, citronellol, citral, orange oil, coriander oil, borneol, fruit extract, and the like. Although not limited thereto, the flavor may be contained in 0.50 to 5 parts by weight based on the solid weight of the composition for the smokeless tobacco. In an embodiment, L-menthol, peppermint flavor, and peppermint oil were used as the flavors.

There is no particular limitation as long as the surfactant is able to be used as an edible emulsifier. Although not limited thereto, the surfactant includes glycerin fatty acid ester, sucrose fatty acid ester, sorbitan fatty acid ester, propylene glycol fatty acid ester, soybean phospholipid, stearyl lactylate, sorbitan oleate, sodium lauryl sulfate, hydrogenated polyoxyethylene castor oil, polyoxyethylene octylphenyl ether, and the like. Although not limited thereto, the surfactant may be contained in 1 to 10 parts by weight based on the solid weight of the composition for the smokeless tobacco. In an embodiment, polysorbate 80 was used as the plasticizer.

The sweeting agent may include both natural and artificial sweeting agents. Although not limited thereto, the sweeting agent includes a water-soluble sweeting agent such as monosaccharide, disaccharide and polysaccharide (i.e., xylose, ribose, sucrose, maltose, fructose, glucose, maltose, mannose), sucralose, aspartame, sodium saccharin, stevioside, rebaudioside, and thaumatin. Although not limited thereto, the sweeting agent may be contained in 0.001 to 1.0 parts by weight based on the solid weight of the composition for the smokeless tobacco. In an embodiment, the sucralose, the xylitol, the stevioside, and the like were used as the sweeting agents.

There is no particular limitation as long as the coloring agent is able to be used as a food coloring agent. The coloring agent may include both natural and artificial coloring agents. As limited thereto, the coloring agent may include green No. 3, red No. 2, red No. 3, blue No. 1, blue No. 2, yellow No. 4, and yellow No. 5 as tar-based coloring agents. In addition, β-carotene, water-soluble annatto, copper sulfate, ferric oxide, caramel, copper and sodium iron chlorophyllin, titanium oxide, and the like may be included as non-tar-based coloring agents. Although not limited thereto, the coloring agent may be contained in 0.0001 to 1.0 parts by weight based on the solid weight of the composition for the smokeless tobacco. In an embodiment, the blue No. 1 was used as the coloring agent.

In addition, the composition for the smokeless tobacco may additionally contain at least one type of known diluents.

Orally Dissolvable Film-Type Smokeless Tobacco

FIG. 1 is a view showing a packaging state of orally dissolvable film-type smokeless tobacco including a first region according to an embodiment. FIG. 2 is a schematic perspective view of orally dissolvable film-type smokeless tobacco including a first region and a second region according to an embodiment. In addition, FIG. 3 is a view showing a packaging state of orally dissolvable film-type smokeless tobacco including a first region and a second region according to an embodiment.

As shown in FIG. 1, the orally dissolvable film-type smokeless tobacco may be formed as orally dissolvable film-type smokeless tobacco 1 composed of only a first region. The first region may be formed by coating the composition for the smokeless tobacco containing 0.01 to 4 parts by weight of the nicotine activator; 40 to 80 parts by weight of the binder; 2 to 10 parts by weight of the plasticizer; the flavor, the surfactant, the coloring agent, the sweeting agent, and the diluent. A reference numeral 22 of FIG. 1 denotes a lower packaging material of the smokeless cigarette 1, a reference numeral 24 denotes an upper packaging material of the smokeless cigarette 1, and a numeral 26 denotes an adhesive.

In addition, as shown in FIG. 2, the smokeless tobacco may be formed as orally dissolvable film-type smokeless tobacco 10 including both a first region 12 and a second region 14. The orally dissolvable film-type smokeless tobacco 10 includes the first region 12 formed by coating the composition for the smokeless tobacco in the film form; and the second region 14 formed by coating a flavor composition, a functional food composition, a beauty treatment composition, a pharmaceutical composition, or a mixture thereof in the film form to be adjacent to the first region.

That is, the orally dissolvable film-type smokeless tobacco 10 including both the first region 12 and the second region 14 may be formed of the smokeless tobacco composition containing the nicotine activator as the main component in the first region 12, and the second region 14 may be formed of the flavor composition, the functional food composition, the beauty treatment composition, the pharmaceutical composition, or the mixture thereof, excluding the nicotine activator.

When the second region 14 formed of the flavor composition is further included, the acceptability of the smokeless tobacco may be improved. Although not limited thereto, the flavor composition may contain the plasticizer, the surfactant, the flavor, the coloring agent, the sweeting agent, and the diluent. There is no particular limitation as long as the plasticizer, the surfactant, the flavor, the coloring agent, the sweeting agent, and the diluent are able to improve the acceptability and are suitable for the coating process. A person skilled in the art may appropriately select and use a known material for the flavor composition.

In addition, when the second region 14 formed of the functional food composition, the beauty treatment composition, or the pharmaceutical composition is further included, the harmfulness to the human body resulted from absorption of the nicotine may be reduced or eliminated. There is no particular limitation as long as the functional food composition, the beauty treatment composition, or the pharmaceutical composition is beneficial to the human body and is suitable for the coating process. A person skilled in the art may appropriately select and use a known functional food composition, such as red ginseng for enhancing immunity with beneficial functionality, vitamin, a nutritional supplement, food good for a bronchial tube and/or a lung. Although not limited thereto, the food good for the bronchial tube and/or the lung may include schisandra, quince, loofah, radish, ginseng, bellflower, pumpkin, pear, persimmon, citron, and the like. The food good for the bronchial tube and/or the lung may help to prevent or alleviate cough, bronchitis, pneumonia, and the like resulted from the absorption of the nicotine. In addition, the beauty treatment or the pharmaceutical composition includes a dental whitening material, a mouthwash, an anticaries compound, an anti-tartar compound, an antioxidant, an anti-inflammatory agent, a pain reliever, an antihistaminic agent, a topical anesthetic, an antibacterial compound, a germicide, an antibiotic, an antiasthmatic agent, and the like.

Furthermore, the smokeless tobacco 10 may further include one or more additional regions adjacent to the first region 12 or the second region 14. Thus, for example, a smokeless tobacco that is divided into a second region and a third region with different functions may be formed. Only the first region of the smokeless tobacco may be ingested as needed based on the above component, or the second region and/or the third region may be ingested based on the acceptability.

At least one of the composition for the smokeless tobacco, the flavor composition, the functional food composition, the beauty treatment composition, the pharmaceutical composition, and the mixture thereof may further contain the coloring agent. When the coloring agent is contained as described above, the first region 12 and the second region 14 may be distinguished from each other, so that the first region 12 and the second region 14 of the smokeless tobacco may be selectively ingested. That is, only the first region 12 of the smokeless tobacco may be ingested as needed, or the first region 12 and only a portion of the second region 14 may be ingested based on the acceptability. In addition, when the coloring agent is contained as described above, aesthetics of the smokeless tobacco may be improved.

The smokeless tobacco may be in a form of a rectangular or elliptical film to properly adjust a disintegration speed while being placed in the oral cavity of the user.

The smokeless tobacco may have a surface area of 400 to 800 mm² and a thickness of 50 to 100 μm, but may not be limited thereto. When the surface area and the thickness of the smokeless tobacco are respectively out of the above ranges, the intraoral disintegration speed and the intraoral intake rate may be lowered.

The smokeless tobacco may have a moisture content of 3 to 5 parts by weight and a pH of 7 to 9, but may not be limited thereto.

The smokeless tobacco may be substantially completely disintegrated within 5 minutes after being placed in the oral cavity. It may be appropriate that the smokeless tobacco is substantially completely disintegrated within 3 minutes after being placed into the oral cavity, and it may be more appropriate that the smokeless tobacco is substantially completely disintegrated within 2 minutes, but the present disclosure may not be limited thereto. Therefore, the smokeless tobacco may be immediately released so as to quickly meet needs of the user who needs the nicotine.

The smokeless tobacco may be disintegrated within 5 minutes after being placed into the oral cavity and gradually release the nicotine until about 50 minutes has elapsed to induce sustained release. Accordingly, the smokeless tobacco may satisfy both rapid nicotine craving relief and continuous nicotine craving relief.

As described above, the orally dissolvable film-type smokeless tobacco may use the composition for the smokeless tobacco containing the nicotine activator of the low dose, so that the absorption of the nicotine may be increased and the intraoral disintegration time may be shortened. In addition, because the smokeless tobacco is in the orally dissolvable film-type, the intraoral intake rate of the nicotine may be improved. The orally dissolvable film-type smokeless tobacco rapidly dissolves in the oral cavity, so that the nicotine at a level substantially equivalent to that of a high-dose smokeless tobacco product may be absorbed through capillaries of oral mucosa. This is because, as described above, even though the nicotine activator is contained in the low dose in the smokeless tobacco, the absorption of the nicotine may become relatively high because of a reaction of the body for maintaining a nicotine content in a blood at a level equal to or above a certain level. In addition, as described above, the smokeless tobacco may satisfy both the rapid nicotine craving relief and the continuous nicotine craving relief

Method for Manufacturing Orally Dissolvable Film-Type Smokeless Tobacco

According to an embodiment, the method for manufacturing the orally dissolvable film-type smokeless tobacco includes forming the first region by discharging the composition for the smokeless tobacco in a single dose through a first nozzle and coating the discharged composition on a packaging material; discharging the flavor composition, the functional food composition, the beauty treatment composition, the pharmaceutical composition, or the mixture thereof in a single dose through a second nozzle and coating the same on the packaging material to be adjacent to the first region to form the second region; and drying the first region and the second region.

The composition for the smokeless tobacco for forming the first region may be prepared, for example, by following processes.

First, the plasticizer and the surfactant are dissolved in purified water in a first preparation tank.

The solution in which the plasticizer and the surfactant are dissolved in the first preparation tank is homogenized by optionally adding the flavor, the sweeting agent, and the like thereto.

Then, the additional flavor (the L-menthol) that was dissolved in purified water in a separate container is optionally added into the first preparation tank to homogenize the solution in the first preparation tank.

Then, the nicotine oil and the binder, which are the main components, and optionally the additional flavor are added into the first preparation tank to homogenize the solution in the first preparation tank.

The first preparation tank is depressurized, so that the composition for the smokeless tobacco in the first preparation tank is cooled and degassed to remove air bubbles.

In addition, the flavor composition for forming the second region may be prepared by following processes.

First, the plasticizer and the surfactant are dissolved in purified water in a second preparation tank.

The solution in which the plasticizer and the surfactant are dissolved in the second preparation tank is homogenized by optionally adding the flavor, the coloring agent, the sweeting agent, and the like.

Then, the flavor (the L-menthol) that was dissolved in purified water in a separate container is optionally added into the second preparation tank to homogenize the solution in the second preparation tank.

Then, the binder and optionally the additional flavor are added into the second preparation tank to homogenize the solution in the second preparation tank.

The second preparation tank is depressurized, so that the flavor composition in the second preparation tank is cooled and degassed to remove air bubbles.

The first region is formed by discharging the composition for the smokeless tobacco prepared above in the single dose through the first nozzle and coating the discharged composition on the packaging material.

Then, the second region is formed by discharging the flavor composition prepared above in the single dose through the second nozzle and coating the discharged flavor composition on the packaging material to be adjacent to the first region.

FIG. 3 is a view showing a packaging state of the orally dissolvable film-type smokeless tobacco 10 including the first region 12 and the second region 14 according to an embodiment.

Referring to FIG. 3, as described above, the coating of the first region 12 and the second region 14 does not require additional slitting and cutting processes because the compositions are discharged in the single dose. In addition, the coating of the first region 12 and the second region 14 is perform on a top face of the lower packaging material 22 and dried, then covered with the upper packaging material 24 after foreign matter inspection is performed, and then is sealed by the adhesive 26 on the packaging material, so that there is no need for a separate storage step and productivity is improved.

The drying step may be performed at 50 to 90° C. As described above, the entire processes including the drying process are performed at a temperature lower than 100° C., so that process cost may be reduced compared to conventional processes requiring a high-temperature melting process.

The coating step of the first region 12 and the second region 14 may be performed by an apparatus for manufacturing a multi-column multi-medicine oral dissolving film disclosed in Korean Patent No. 10-1547219 of the present applicant.

In the method for manufacturing the orally dissolvable film-type smokeless tobacco, the orally dissolvable film-type smokeless tobacco is manufactured by being coated with predetermined size and thickness. Thus, the slitting and cutting processes are unnecessary, so that the processes are simple and the productivity is excellent. Further, in the method for manufacturing the orally dissolvable film-type smokeless tobacco, the orally dissolvable film-type smokeless tobacco is manufactured by being directly coated on the packaging material, so that there is no need to store the semi-finished product separately, thereby solving a problem associated with the semi-finished product storage. In addition, in the method for manufacturing the orally dissolvable film-type smokeless tobacco, the orally dissolvable film-type smokeless tobacco is formed in a single layer and formed in a single process and does not require the extrusion or the high-temperature melting process, so that the number of processes is small and the productivity is excellent.

Hereinafter, the present disclosure will be described in more detail through examples.

EXAMPLES

Example 1. Manufacture of Film-Type Smokeless Tobacco Based on Nicotine Content

The glycerin as the plasticizer, the polysorbate 80 as the surfactant, the L-menthol as the flavor, the blue No. 1 as the coloring agent, the sucralose, the peppermint, the xylitol, and the stevia as the sweeting agent, and the diluent were added into the purified water, and stirred to be dissolved or dispersed, and then the solution was homogenized using a homogenizer (PL-HMZ30DN Poong Lim Tech).

The nicotine oil with various contents and the hydroxypropylmethylcellulose as the binder were added to the solution, and then the solution was homogenized again using the same homogenizer. After gas in the film preparation solution was removed under a vacuum condition, the solution was coated on a pouch, which is the packaging material, with a casting machine to have a size of 22 mm in width and 28 mm in length, and a thickness of about 91 μm. Thereafter, the solution was dried for 10 to 20 minutes at a temperature in a range from 50 to 90° C. to manufacture the film-type smokeless tobacco containing the nicotine.

Acceptability and disintegration degree of the film-type smokeless tobacco manufactured as described above were identified. Table 1 shows acceptability and a disintegration time based on a nicotine content of each of Example 1 and Comparative example 1. Comparative example 1-1 used Niquitin®, a smoking aid product of GlaxoSmithKline, with a nicotine content of 25 mg.
