Description

[Technical Field]

[0001] The present invention relates to nicotine pouch compositions as set forth in the claims. [Background technology]

[0002] The delivery of nicotine through smoking has many well-known drawbacks, particularly health-related issues such as the inclusion of carcinogens. However, tobacco substitutes also have drawbacks, such as insufficient craving relief for users. Summary of the Invention [Problem to be solved by the invention]

[0003] An object of one embodiment of the present invention is to provide a nicotine-containing pouch, for example as a tobacco substitute, that can solve the above problems. A further problem in the prior art is that the desired nicotine release should be attractive from the user's perspective to the user of the pouch.

[0004] Furthermore, a further problem associated with the prior art may be that pouches as delivery vehicles for nicotine are somewhat costly, which places restrictions on how the pouches can be designed to control manufacturing costs. [Means for solving the problem]

[0005] The present invention relates to a nicotine pouched product, the nicotine pouched product comprising: a pouch composition; a pouch membrane enclosing the pouch composition; Including, The pouch composition comprises: at least one water-insoluble fiber; Water in an amount of at least 15% by weight of the composition; Nicotine and Including, The pouch membrane further comprises nicotine in an amount of at least 15% by weight of the total nicotine content in the pouched product.

[0006] An advantage of the present invention may be that the inclusion of said additional nicotine in the pouch membrane promotes a relatively rapid release of nicotine, such that the pouched product releases nicotine from the pouch composition, but in addition, nicotine is also released from the pouch membrane itself, thereby significantly improving nicotine release over pouches that contain nicotine only in the pouch composition.

[0007] In many conventional pouches, attention is usually focused on the total amount of nicotine released within the use period of 30 minutes or 60 minutes.However, the relief of nicotine craving is still not necessarily optimal.Instead, by adding nicotine to the pouch membrane, the release of nicotine is increased, especially in the first few minutes after starting use, thereby providing a highly desirable release of nicotine and relief of craving.This advantage is achieved, for example, without requiring special modification of the pouch composition, but instead by carefully distributing the nicotine in the pouched product so that at least a portion of the nicotine is located within the pouch membrane.In addition, since the nicotine dosage can be distributed between the pouch composition and the pouch membrane instead, it is achieved without requiring an increase in the total amount of nicotine.

[0008] A further advantage of the present invention may be that by providing a combination of the claimed moisture content and the at least one water-insoluble fiber, a highly desirable mouthfeel can be obtained without the use of tobacco, while having the claimed moisture content may promote a more rapid release, especially within the first few minutes of use.

[0009] Therefore, in the context of the present invention, it should be understood that the pouch membrane contains an amount of nicotine, and that said amount of nicotine in the pouch membrane is at least 15% by weight of the total nicotine content in the pouched product.

[0010] Furthermore, the pouched product contains nicotine in both the pouch composition and the pouch membrane. Thus, the nicotine in the pouched product includes the nicotine in the pouch composition and the nicotine in the pouch membrane.

[0011] In an advantageous embodiment of the invention, said at least one water-insoluble fiber is provided as a powder and said pouch membrane comprises at least one further water-insoluble fiber. In an advantageous embodiment of the invention, at least 15% by weight of the total nicotine content in the pouched product is released within a period of not more than 120 seconds upon oral administration.

[0012] In one embodiment of the present invention, this is measured by placing the pouched product into a reaction tube containing 10 mL of 0.02 M potassium dihydrogen phosphate buffer (adjusted to pH 7.4), removing the pouched product, and determining the remaining portion of nicotine in the pouched product.

[0013] The above in vitro method is described in more detail in Example 5F. In an advantageous embodiment of the invention, 15-40% by weight of the total nicotine content in the pouched product is released within a period of not more than 120 seconds upon oral administration.

[0014] In one embodiment of the invention, the pouch composition is provided in a pouch and is adapted to release at least 15% by weight of the total nicotine content of the pouched product within a period of 120 seconds when subjected to the in vitro release experiment described in Example 5F, such as at least 20% by weight of the total nicotine content of the pouched product, such as at least 30% by weight of the total nicotine content of the pouched product.

[0015] In one embodiment of the invention, the pouch composition is provided in a pouch and is adapted to release 15-50% by weight of the total nicotine content of the pouched product within a period of 120 seconds when subjected to the in vitro release experiment described in Example 5F, such as 20-45% by weight of the total nicotine content of the pouched product, such as 30-40% by weight of the total nicotine content of the pouched product.

[0046] In an advantageous embodiment of the invention, the additional nicotine in the pouch membrane is provided by processing nicotine from the pouch composition into the pouch membrane.

[0047] In one embodiment of the present invention, the processing of nicotine from the pouch composition into the pouch membrane may include exposing the pouched product to a predetermined temperature and humidity. In one embodiment of the invention, the nicotine in the pouch membrane is applied to the pouch membrane by a nicotine dispenser.

[0048] In an advantageous embodiment of the invention, the nicotine in the pouch membrane is applied to the pouch membrane by film coating or spraying. In an advantageous embodiment of the invention, the nicotine in the pouch membrane is applied to the pouch membrane by dipping the pouched product into liquid nicotine, for example diluted liquid nicotine.

[0049] In one embodiment of the present invention, the nicotine in the pouch membrane is applied to the pouch membrane prior to filling the pouch membrane with the pouch composition. In an advantageous embodiment of the invention, additional nicotine is applied to the pouch membrane during its manufacture.

[0050] In an advantageous embodiment of the invention, the nicotine in the pouch composition is in the same form as the further nicotine in the pouch membrane. In an advantageous embodiment of the present invention, the pouch composition has a water content of 15 to 70% by weight of said pouch composition, such as 15 to 65% by weight of said pouch composition, such as 15 to 50% by weight of said pouch composition, such as 25 to 50% by weight of said pouch composition, such as 30 to 40% by weight of said pouch composition.

[0051] In an advantageous embodiment of the present invention, the pouch composition has a water content of 15 to 70% by weight of said pouch composition, such as 15 to 50% by weight of said pouch composition, such as 15 to 40% by weight of said pouch composition, such as 15 to 30% by weight of said pouch composition, such as 15 to 25% by weight of said pouch composition.

[0052] Water may be added as a separate ingredient that is fully or partially mixed with other ingredients, such as fiber. For example, if free base nicotine is added as a mixture of free base nicotine with ion exchange resin and water, a significant amount of the water in the final pouch composition will come from the free base nicotine-ion exchange resin-water premix. For example, if the final amount pouch composition contains 5% water from the free base nicotine-ion exchange resin-water premix, up to one-third of the water in the pouch composition will come from the free base nicotine-ion exchange resin-water premix.

[0053] In an advantageous embodiment of the invention, the pouch composition has a water content of not more than 60% by weight of said pouch composition, such as not more than 50% by weight of said pouch composition, such as not more than 40% by weight of said pouch composition, such as not more than 30% by weight of said pouch composition.

[0054] In an advantageous embodiment of the present invention, the water insoluble fiber of the pouch composition is selected from water insoluble vegetable fibers, wheat fiber, pea fiber, rice fiber, maize fiber, oat fiber, tomato fiber, barley fiber, rye fiber, sugar beet fiber, buckwheat fiber, potato fiber, apple fiber, cocoa fiber, bamboo fiber, bran fibers, powdered cellulose and any combination thereof.

[0055] Powdered cellulose within the scope of the present invention is understood to be cellulose prepared by processing α-cellulose obtained as pulp from several types of fibrous plant material, such as wood pulp.

[0056] In an advantageous embodiment of the present invention, the water-insoluble fiber of the pouch composition is selected from oat fiber, wheat fiber, pea fiber, powdered cellulose and any combination thereof.

[0057] In an advantageous embodiment of the invention, the water-insoluble fiber comprises MCC. In an advantageous embodiment of the invention, the water-insoluble fibre is powdered. In an advantageous embodiment of the invention, the water insoluble fibre of the pouch composition has a water binding capacity of at least 200%, such as at least 300%, such as at least 400%.

[0058] An advantage of the above embodiment may be that the high water binding capacity allows for a pouch composition with a high moisture content. In one embodiment of the present invention, the water-insoluble fiber of the pouch composition has a water binding capacity of 200% to 1500%, such as 300 to 1300%, such as 200 to 800%, such as 300 to 800%, such as 400 to 600%.

[0059] In one embodiment of the present invention, the water-insoluble fiber has a water binding capacity of 200 to 1500%, such as 300 to 1300%, such as 300 to 900%, such as 300 to 700%, such as 400 to 700%.

[0060] In one embodiment of the present invention, the water-insoluble fiber has a water binding capacity of 200 to 1500%, such as 400 to 1500%, such as 500 to 1500%, such as 500 to 1200%, such as 500 to 1000%.

[0061] In one embodiment of the invention, the water-insoluble fiber has a swelling capacity of at least 5.0 mL / g, such as 5.0 to 20 mL / g. The advantage of the above embodiment is that the amount of water-insoluble fiber can be reduced without compromising the mouthfeel during use. When a certain amount of water-insoluble fiber substitutes for the water-soluble ingredients, the swelling of the water-insoluble fiber will prevent the dissolution of the water-soluble ingredients during use, so that the user will not experience any reduction in the pouch contents during use.

[0062] In an advantageous embodiment of the invention, the composition has a bulk density of at most 0.8 g / cm, such as at most 0.7 g / cm, such as at most 0.6 g / cm, such as at most 0.5 g / cm.

[0063] The inventive use of compositions having a relatively low bulk density will not only provide a good mouthfeel, but will also provide effective release from the pouch due to the fact that the relatively low bulk density promotes effective salivation, thereby promoting the release of the water-soluble components of the composition. It is noted that low bulk density in combination with the claimed moisture content is particularly attractive when improved user perception is desired.

[0064] At the same time, low density also has the advantage of reducing the amount of raw material used, thereby lowering manufacturing costs. An advantage of the above-described embodiment may be that it results in a low density composition. Surprisingly, the combination of water and sugar alcohol did not result in a very dense, compact, unprocessable pouch composition, but rather allowed for a relatively light weight, low density composition.

[0065] In an advantageous embodiment of the invention, the pouch composition comprises water and water insoluble fibre in a weight ratio of 3.0 or less, such as 2.5 or less, such as 2.0 or less, such as 1.5 or less, such as 1.0 or less.

[0066] In an advantageous embodiment of the present invention, the pouch composition is free of tobacco, tobacco fiber, and tobacco-derived fiber. In some alternative embodiments, the pouch composition may include trace amounts of tobacco. For example, nicotine provided as part of tobacco, such as powdered tobacco, is in addition to the free base nicotine. Such tobacco may be included, for example, to provide tobacco flavor.

[0067] In one embodiment, the pouch composition may include tobacco, tobacco fiber, or tobacco-derived fiber in an amount of 0.1-5.0% by weight of the pouch composition, such as 0.1-3.0% by weight of the pouch composition. Thus, the pouch composition may, in some embodiments, include a small amount of tobacco, which is in addition to the free base nicotine, and thus the pouch composition is not tobacco-based.

[0068] In one embodiment of the invention, the pouch composition is tobacco-free, such as tobacco-free, such as tobacco-free at less than 5.0% by weight, such as tobacco-free at less than 0.1% by weight of the pouch composition, such as tobacco-free at less than 0.5% by weight of the pouch composition, such as tobacco-free at less than 1.0% by weight of the pouch composition, such as tobacco-free at less than 3.0% by weight of the pouch composition.

[0069] In one embodiment of the invention, the water-insoluble composition does not include tobacco, tobacco fiber, or fiber derived from tobacco, and therefore in this embodiment, the water-insoluble fiber is a non-tobacco fiber, i.e., does not include tobacco, tobacco fiber, or fiber derived from tobacco.

[0070] In one embodiment of the invention, the membrane comprises water-insoluble fiber of a different origin than the water-insoluble fiber contained in the pouched product. In one embodiment of the present invention, the water-insoluble fiber of the membrane and the water-insoluble fiber of the pouch composition both comprise natural fibers.

[0071] In one embodiment of the present invention, the water-insoluble fiber of the membrane and the water-insoluble fiber of the pouch composition are both natural fibers. In an advantageous embodiment of the present invention, the pouch composition comprises a sugar alcohol selected from the group consisting of sorbitol, erythritol, xylitol, lactitol, maltitol, mannitol, hydrogenated starch hydrolysates, isomalt, or any combination thereof, wherein the composition comprises said sugar alcohol in an amount of 1 to 80% by weight of the pouch composition, such as 5 to 70% by weight of the pouch composition, such as 10 to 60% by weight of the pouch composition.

[0072] In an advantageous embodiment of the invention, the pouch composition comprises a sugar alcohol selected from the group consisting of sorbitol, erythritol, xylitol, lactitol, maltitol, mannitol, hydrogenated starch hydrolysates, isomalt, or any combination thereof; the composition comprises the sugar alcohol in an amount of 1 to 80% by weight of the pouch composition, such as 5 to 70% by weight of the pouch composition, such as 10 to 60% by weight of the pouch composition, and The composition further comprises water insoluble fiber in an amount of 5 to 50% by weight of the pouch composition, such as 10 to 30% by weight of the pouch composition.

[0079] In one embodiment of the present invention, the nicotine pouched product of the second aspect is devised according to the first aspect of the invention or any of its embodiments. DETAILED DESCRIPTION OF THE INVENTION

[0080] As used herein, the term "nicotine" refers to nicotine used as a purified / isolated substance. In particular, nicotine does not refer to tobacco materials that contain nicotine.

[0081] As used herein, the term "pouch composition" refers to a pouched product, i.e., a composition for use in a pouch for oral use that contains nicotine. Also, the terms "nicotine pouch composition" and "pouch composition" are used interchangeably. The pouch composition is not a tobacco-based pouch composition. In some embodiments, the pouch composition may contain a small amount of tobacco as a flavoring, e.g., less than 2% by weight of the composition. In other embodiments, the pouch composition does not contain tobacco.

[0082] As used herein, the term "free base nicotine" refers to nicotine in unprotonated form, and therefore does not include nicotine salts and nicotine provided as a complex of nicotine and ion exchange resin.However, free base nicotine can be mixed with a certain amount of ion exchange resin or a water-soluble composition such as sugar alcohol or water-soluble fiber.Free base nicotine can also be mixed with a water-insoluble composition such as water-insoluble fiber.Free base nicotine includes both free base nicotine extracted from tobacco and free base nicotine produced synthetically, but free base nicotine is not provided in the form of tobacco or powdered tobacco.Typically, free base nicotine is provided as a liquid.

[0083] As used herein, the term "pouch membrane" is intended to refer to a material that forms a container surrounding a cavity. The pouch membrane is designed for administering nicotine into the oral cavity and is therefore suitable for use in the oral cavity, non-toxic, and non-water-soluble. The pouch membrane, which may also be referred to as a web of fibrous material, may form, for example, a woven or non-woven web or fabric. The pouched product may, for example, be formed by sealing two corresponding sections of the web or fabric together along their edges to form a cavity for the nicotine and water-insoluble composition. To release the nicotine, flavorings, and other water-soluble substances, the pouch membrane is water-permeable so that saliva from the oral cavity can penetrate the pouch membrane, where it contacts the nicotine, and enter the cavity, where it contacts the nicotine, flavorings, and other water-soluble substances, thereby releasing the nicotine, flavorings, and other water-soluble substances from the pouch membrane and pouch composition from the pouched product.

[0084] As used herein, the term "powder composition" refers to a composition in the form of a powder, i.e., a composition as particulate matter having a relatively small particle size, for example, of 1 to 1200 micrometers. In particular, powder composition does not refer to powdered tobacco.

[0085] As used herein, the term "humectant" is understood to mean a moisturizing agent used to attract moisture or water in the form of saliva. Humectants typically include compositions that are suitably hygroscopic. In some cases, humectants may also be described as humectants because of their role in attracting moisture. Examples of humectants include glycerol, propylene glycol, alginate, pectin, xanthan gum, modified starch, hydroxypropyl cellulose, triacetin, polyethylene glycol (PEG), and the like.

[0086] As used herein, the term "water soluble" refers to a relatively high water solubility, e.g., a water solubility of a water soluble composition or substance greater than 5 grams per 100 mL of water, measured at 25 degrees Celsius and a pH of 7.0. When referring to a "soluble" composition or substance, water soluble is meant unless otherwise specified.

[0087] As used herein, the term "water-insoluble" refers to a water-soluble composition or substance with a relatively low water solubility, for example, a water solubility of less than 0.1 grams per 100 mL of water, measured at 25 degrees Celsius and a pH of 7.0. When referring to "insoluble," water insolubility is meant unless otherwise specified.

[0088] Typically, the pouch membrane includes an opening with characteristic opening dimensions adapted to the characteristic dimensions of the pouch composition to retain the pouch composition inside the pouch prior to use and / or to retain a portion of the pouch composition, such as a water-insoluble composition, inside the pouch during use.

[0089] In order to obtain a pouch membrane having a suitable opening size in consideration of the pouch composition to be used, the material of the pouch membrane, including, for example, woven fabric and / or nonwoven fabric, can be appropriately selected. In other words, according to various embodiments, the pouch membrane allows the passage of saliva and prevents or blocks the passage of undissolved composition and water-insoluble fibers. The pouch membrane can be any suitable material, for example, woven or nonwoven fabrics (e.g., cotton, fleece, etc.), heat-sealable nonwoven cellulose such as long-fiber paper, or other polymeric materials such as synthetic, semi-synthetic, or natural polymeric materials. One example of a suitable material for the pouch membrane is paper made of pulp and a small amount of wet-strength agent. Materials suitable for use must provide a semi-permeable membrane layer to prevent the powder or composition from leaving the bag or pouch during use. Suitable materials also do not significantly affect the release of nicotine from the pouch.

[0090] More specifically, in terms of material, the pouch membrane can be a natural, synthetic, or semi-synthetic hydrophilic or hydrophobic membrane. It can be made from one or more biocompatible and physiologically acceptable polymeric materials. Examples of suitable materials for the pouch membrane include cellulose acetate and its derivatives, carboxymethylcellulose, polycellulose esters, other cellulose derivatives including ethylcellulose and propylcellulose, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinyl acetate, methacrylate and acrylate polymers, natural rubber, polycarbonate, polyethylene terephthalate, polyester, polyamide, and nylon. Other suitable materials have been mentioned previously in this specification.

[0091] Rayon fibers (i.e., regenerated cellulose), such as viscose rayon fibers, may also be used, for example, in combination with an acrylic polymer to act as a binder in the nonwoven material and provide heat sealing of the pouch membrane during its manufacture. Other binders, such as one or more copolymers of vinyl acetate and acrylic acid esters, may also be used.

[0092] Suitable pouch membranes are available under the trade names "Taboka," CatchDry, Ettan, General, Granit, Goteborgs Rape, GrovSnus White, Metropol Kaktus, Mocha Anis, Mocha Mint, Mocha Wintergreen, Kicks, Probe, Prince, Skruf, TreAnkrare, Camel Snus Original, Camel Snus Frost, and Camel Snus Spice. The pouch membrane provides a liquid-permeable container of a type that can be considered similar in properties to the mesh-type materials used in the construction of tea bags. The desired component of the nicotine composition to be released diffuses through the pouch membrane and into the user's mouth.

[0093] The pouch membrane material may have the form of a mesh, a sieve, perforated paper, a permeable fabric, or the like. For example, a pouch material made from mesh-like rice paper or perforated rice paper may dissolve in the user's mouth. In some exemplary embodiments, the pouch membrane material may be made using water-dispersible film-forming materials (e.g., binders such as alginate, carboxymethylcellulose, xanthan gum, pullulan, etc.), as well as those materials in combination with materials such as comminuted cellulose derivatives (e.g., fine-grained wood pulp). Preferred pouch materials, while water-dispersible or soluble, may be designed and manufactured so that a significant amount of the nicotine content will permeate the pouch material under normal use conditions before the pouch loses its physical integrity. If desired, flavoring ingredients, disintegration aids, and other desired ingredients may be incorporated into or applied to the pouch material.

[0094] Examples of various types of pouch membrane materials are described in U.S. Patent No. 5,167,244 to Kjerstad. Fleece materials for use as pouch membranes are described, for example, in WO 2008 / 152469, GB 673,587, and EP 2692254, which are incorporated herein by reference.

In one embodiment of the invention, the pH control agent is selected from the group consisting of acetic acid, adipic acid, citric acid, fumaric acid, glucono-δ-lactone, gluconic acid, lactic acid, malic acid, maleic acid, tartaric acid, succinic acid, propionic acid, ascorbic acid, phosphoric acid, sodium orthophosphate, potassium orthophosphate, calcium orthophosphate, sodium diphosphate, potassium diphosphate, calcium diphosphate, pentasodium triphosphate, pentapassium triphosphate, sodium polyphosphate, potassium polyphosphate, carbonic acid, sodium carbonate, sodium bicarbonate, potassium carbonate, calcium carbonate, magnesium carbonate, magnesium oxide, or any combination thereof.

[0096] In one embodiment of the present invention, the pH control agent is selected from sodium carbonate, sodium bicarbonate, potassium carbonate, calcium carbonate, magnesium carbonate, or any combination thereof.

[0097] According to various embodiments of the present invention, one or more sugar alcohols may be included in the pouched product as part of the pouch composition, for example, as a sweetener, a humectant, or as a carrier or portion thereof. Suitable sugar alcohols include sugar alcohols selected from the group of sorbitol, erythritol, xylitol, lactitol, maltitol, mannitol, hydrogenated starch hydrolysates, isomalt, or any combination thereof.

[0098] In one embodiment of the present invention, the pouch composition comprises a high intensity sweetener. Preferred high-intensity sweeteners include, but are not limited to, sucralose, aspartame, salts of acesulfame such as acesulfame potassium, alitame, saccharin and its salts, cyclamic acid and its salts, glycyrrhizin, dihydrochalcones, thaumatin, monellin, stevioside, and the like, alone or in combination.

[0099] In one embodiment of the present invention, the pouch composition comprises sugar and / or sugarless sweeteners, such as sugar alcohols. In one embodiment of the present invention, the pouch composition comprises sugar and / or sugarless sweeteners in an amount of 1.0 to about 80% by weight of the pouch composition, more typically 5 to about 70% by weight of the pouch composition, and more commonly 10 to 30% by weight or 5 to 25% by weight of the pouch composition. In some other embodiments, the sugar and / or sugarless sweeteners comprise 10 to 60% by weight of the pouch composition, or 10 to 50% by weight of the pouch composition. The sugar and / or sugarless sweeteners may function not only as sweeteners but also as humectants. In some embodiments, the approximate amounts of sugar and / or sugarless sweeteners can be further limited by the inclusion of certain ingredients. In some embodiments, the content of sugar and / or sugarless sweeteners in the pouch composition is 20% or less by weight of the pouch composition, such as 15% or less by weight of the pouch composition, such as 10% or less by weight of the pouch composition, such as 5% or less by weight of the pouch composition.

[0100] Sweeteners can often support the flavor profile of the pouch composition. Sugar sweeteners generally include, but are not limited to, sugar-containing ingredients commonly known in the pouch art, such as sucrose, dextrose, maltose, saccharose, lactose, sorbose, dextrin, trehalose, D-tagatose, dry invert sugar, fructose, levulose, galactose, corn syrup solids, glucose syrup, hydrogenated glucose syrup, etc., alone or in combination. These sugar sweeteners may also be included as humectants.

[0101] The sweetener can be used in combination with sugarless sweeteners. Generally, sugarless sweeteners include sugar-free ingredients that are commonly known for their sweetening properties, including, but not limited to, sugar alcohols such as sorbitol, mannitol, xylitol, hydrogenated starch hydrolysates, maltitol, isomalt, erythritol, and lactitol, either alone or in combination. These sugarless sweeteners can also be included as humectants.

[0102] In an embodiment of the present invention, the pouch composition further comprises water-soluble fiber. Non-limiting examples of water-soluble fiber include inulin, polydextrose, and psyllium plant fiber. Other water-soluble dietary fibers may also be used.

[0103] In one embodiment of the present invention, the pouch composition comprises a flavoring. The flavoring may typically be present in an amount of 0.01 to 15% by weight of the total composition of the pouch, such as 0.01 to 5% by weight of the total composition. In an alternative embodiment, the pouch composition may be free of flavoring.

[0104] Non-exhaustive examples of flavorings suitable for one embodiment of the present invention include coconut, coffee, chocolate, vanilla, citrus fruits such as grapefruit, orange, lime, bergamot, or lemon, menthol, licorice, caramel aroma, honey aroma, peanut, walnut, cashew, hazelnut, almond, pineapple, strawberry, raspberry, tropical fruits, cherry, cinnamon, peppermint, wintergreen, spearmint, eucalyptus, and mint, fruit essences such as apple, pear, peach, strawberry, apricot, raspberry, cherry, pineapple, lemongrass, lime, chili (capsaicin), citrus, tobacco flavoring, bergamot, and plum essence. Essential oils include peppermint, spearmint, menthol, eucalyptus, clove oil, bay oil, anise, thyme, cedar leaf oil, nutmeg, and oils of the fruits listed above.

[0105] In various embodiments of the present invention, the pouch composition comprises a release controlling composition for controlling the release of the pouch composition and / or portions thereof, particularly nicotine.

[0106] According to various embodiments, the controlled-release composition may be selected from the group consisting of metal stearates, modified calcium carbonate, triglycerides (e.g., hydrogenated vegetable oils, partially hydrogenated vegetable oils, and / or tallow), polyethylene glycol, polyoxyethylene monostearate, tallow, silicates, silicon dioxide, talc, magnesium stearate, calcium stearate, fumed silica, powdered hydrogenated cottonseed oil, emulsifiers, hydrogenated soybean oil, and mixtures thereof. In particular, metal stearates such as magnesium stearate may be advantageous.

[0107] The controlled release composition can be added to the pouch composition in a variety of ways. For example, the controlled release composition can be added by fully powder mixture during the last few minutes of final mixing.

[0108] Alternatively, the controlled release composition may be added after the granulation step of the granulated premix. Additionally, the controlled release composition may be added only as part of the pouch composition, such that two different nicotine release profiles are obtained. Additionally, two or more portions of the pouch composition may contain different amounts of the controlled release composition, if any, thereby providing more complex and tailored nicotine release profiles.

[0109] Controlled release compositions such as magnesium stearate may have an occlusive effect and can be used to control the release of nicotine and the dissolution rate of the pouch. [Example]

[0169] Pouches PPC23-PPC26 show the use of varying amounts of buffering agent (here sodium carbonate). With more basic buffering agent to achieve a more alkaline environment, the preservative (here potassium sorbate) is less needed and is therefore omitted in PPC25-PPC26, which have the highest amount of alkaline buffering agent.

[0170] Example 3D - Pouch Pouches PPC31-PPC32 are prepared similarly to pouches PPC1-PPC5 of Example 3A, but using Nicotine Premix I and III, respectively.

[0171] Pouches PPC31 to PPC35 are manufactured as follows. Nicotine and sugar alcohol (e.g., xylitol, sorbitol, maltitol) are weighed. Nicotine is slowly added to the sugar alcohol powder while stirring (KitchenAid mixer operated at approximately 30 RPM for approximately 30 minutes). The resulting granules are sieved and placed on a tray. The resulting powder is dried overnight at ambient temperature and then sieved to obtain the nicotine-sugar alcohol premix. It is also possible to add a certain amount of water to the nicotine before mixing with the sugar alcohol. Such water will then evaporate during drying.

[0172] The fiber and water were mixed for 5 minutes using a planetary Bear Varimixer mixer.

[0248] Example 4A - Nicotine Application to Pouch Membrane The nicotine pouches were placed in a sealed treatment container at a temperature of approximately 25° C. The temperature of the nicotine pouches was kept constant for 14 days while the container remained sealed.

[0249] After 14 days of treatment, the containers were opened and the pouch membrane and pouch composition were tested for nicotine content. Example 4B - Application of Nicotine to Pouch Membrane The pouched product was immersed in liquid nicotine (diluted with propylene glycol to approximately 20% nicotine concentration) and the nicotine was applied to the pouch membrane.

[0250] The soaking process lasted for about 5 minutes. The pouch membrane and pouch composition were then tested for nicotine content. Example 4C - Application of Nicotine by Nebulization A liquid nicotine solution (diluted with propylene glycol to a nicotine concentration of approximately 20%) was applied to the pouched products by spraying.

[0251] The pouched product was then allowed to dry under ambient conditions for approximately 10 minutes. The pouch membrane and pouch composition were then tested for nicotine content.

[0252] Example 4D - Pouch Membrane Pouched products were manufactured using different pouch membranes with pouch composition PPC55. PPC55-A was made with a pouch membrane having fibers consisting essentially of regenerated cellulose (viscose) and processed according to Example 4A. PPC55-B was made with a pouch membrane having fibers that were a combination of regenerated cellulose (viscose) and synthetic fibers and processed according to Example 4A. PPC55-C was made with a pouch membrane having fibers that were a combination of viscose and synthetic fiber materials and processed according to Example 4A. The fiber composition of the pouch membrane for PPC55-C was different from that of PPC55-B, with PPC55-C having a slightly denser composition.

[0253] Example 5A - Nicotine Application to Pouch Membrane A pouched product was prepared according to Example 4A using the pouch composition PPC44 of Example 3E. The resulting pouched product was examined for nicotine content in the pouch membrane. Of the total nicotine content in the pouched product of approximately 12 mg added to the pouch composition during manufacture, the processed pouched product contained approximately 8.5 mg of nicotine in the pouch composition and approximately 3.5 mg of nicotine in the pouch membrane, representing approximately 29% by weight of the total nicotine. The pouch membrane had a weight equivalent to approximately 12% by weight of the pouched product when the pouched product was prepared.

[0254] Example 5B - Nicotine Release Next, the pouch composition and the pouch membrane of the processed pouch PPC44 of Example 5A were tested separately to evaluate the amount of nicotine released.In the in vitro experiment according to Example 5F, it was observed that the pouch composition itself (without the pouch membrane) released about 40% by weight of its nicotine content at 10 minutes.When the corresponding test was applied, the pouch membrane itself released about 92% of its weight at 10 minutes.This confirmed that the nicotine of the pouch membrane was released much faster and more effectively than the nicotine of the pouch composition.

[0255] Example 5C - Treatment Time Pouched products made with PPC44, PPC54, and PPC55 were treated according to Example 4A. At 0, 1, 4, and 7 days after treatment began, the pouched products made with PPC44, PPC54, and PPC55 were tested for nicotine content in the pouch membrane. The results are shown in Table 15.

[0256] [Table 20]

[0257] As can be seen from Table 15, the amount of nicotine in the pouch membrane can be varied by adjusting the nicotine source and by adjusting the treatment time. Longer treatment times result in higher amounts of nicotine in the pouch membrane. Also, replacing Nicotine Premix II (PPC44) with Nicotine Premix VI (PPC55) results in significantly faster and more efficient delivery of nicotine to the pouch membrane.

[0258] Example 5D - Release from Pouched Products Similarly, the in vitro release from the pouched products of PPC44, PPC54, and PPC55 was tested at 0, 1, 4, and 7 days after the start of treatment. The results of nicotine release from the pouched products at 10 minutes are shown in Table 16.

[0259] [Table 21]

[0260] As shown in Table 16, the application of nicotine to the pouch membrane clearly leads to a more efficient release of nicotine from the pouched product. The longer the treatment time, the more nicotine is incorporated into the pouch membrane. As shown above, the extremely high release rate of 92% from the pouch membrane indicates that increasing the amount of nicotine incorporated into the pouch membrane through treatment leads to a more efficient release of nicotine from the pouched product.

[0261] Example 5E - Release Testing (In Vivo) The releasability of the pouches was evaluated by assessors, preferably a panel of at least 8 assessors, each of whom was given a pouch to place in the oral cavity, specifically on the upper lip.

[0262] After 2, 5, 10, 30, or 60 minutes, the pouch was removed from the subject's mouth. The amount of nicotine remaining in the pouch was measured using standard HPLC techniques.

[0263] Two pouches were tested at each time point, and the average of the results obtained at each time point was used to generate a profile of the nicotine content in the pouch over time. The amount of nicotine released was then obtained by subtracting the amount of nicotine remaining in the pouch from the initial dose of nicotine in the pouch tested.

[0264] Example 5F - Release Testing (In Vitro) The release properties of the pouches were verified in an in vitro experiment. At a temperature of T=37° C., each pouch was placed in a reaction tube containing 10 mL of 0.02 M potassium dihydrogen phosphate buffer (pH adjusted to 7.4).

[0265] No stirring or shaking was performed during the release experiments. After 2, 5, 10, 30, and 60 minutes, the pouch was removed from the buffer solution and allowed to drip. The wet pouch was then gently pulled over the edge of the reaction tube to remove excess buffer from the wet pouch.

[0266] The amount of nicotine remaining in the pouch was determined using standard HPLC techniques. Two pouches were tested at each time point, and the average of the results obtained at each time point was used to generate a profile of the nicotine content in the pouch over time.

[0267] The amount of nicotine released was then obtained by subtracting the amount of nicotine remaining in the pouch from the initial dose of nicotine in the pouch tested. Example 5H - Release from pouches with different pouch membranes The release of nicotine from pouched products PPC55-A, PPC55-B and PPC55-C according to Example 4D was tested according to the method of Example 5F, and the results are shown in Table 17.

[0268] [Table 22]

[0269] Pouches PPC55-A, PPC55-B, and PPC55-C were also tested for nicotine content in the pouch membrane prior to release testing. The pouch membrane of pouched product PPC55-A had a nicotine content of 22.4% by weight of the total nicotine content in the pouched product. The pouch membrane of pouched product PPC55-B had a nicotine content of 19.0% by weight of the total nicotine content in the pouched product. The pouch membrane of pouched product PPC55-C had a nicotine content of 29.7% by weight of the total nicotine content in the pouched product.

[0270] These results indicate that the pouch membrane material influences both the amount of nicotine that can be accommodated in the pouch membrane and the amount of nicotine released during the study. In particular, the use of a viscose-based pouch membrane (i.e., a pouch membrane with fibers consisting essentially of viscose, PPC55-A) resulted in significantly higher release, especially at the earliest time points, compared to pouch membranes containing both viscose and synthetic fibers (PPC55-B and PPC55-C).

[0271] Example 5I - Nicotine Content in Pouch Membrane The nicotine content in the pouch membranes of the pouched products Comp. 10, PPC101, and PPC102, which were processed according to Example 4A, was measured over a shortened period of time. Testing was performed one day after treatment, and the average results are shown in Table 18.

[0272] [Table 23]

[0273] The results in Table 18 demonstrate that having a high water content in the pouch composition promotes effective dispensing of nicotine into the pouch membrane. The test results of PPC101 show that the nicotine content in the pouch membrane increases significantly during the initial measurement, and complete treatment has not yet been achieved.Example 4A shows that the treatment period is 14 days until the desired level of nicotine in the membrane is achieved.However, the treatment time can be highly dependent on, for example, the amount of water.
