The second wax material being a different wax material than the first wax material.

Description

The present invention relates to flavoring delivery systems for smoking products where the flavoring material is encapsulated in wax and combined with tobacco for smoking products.

Combustible smoking products, such as cigarettes, typically contain a tobacco substrate, which is cut tobacco (usually in the form of cut filler) surrounded by a paper wrapper that forms a tobacco rod. To use a cigarette, the smoker lights one end of the cigarette and the rod of cut tobacco begins to burn. The smoker then inhales the smoke by taking a puff on the opposite end or end of the cigarette that is brought to the mouth, which usually contains a filter. In traditional cigarettes, tobacco burns and generates temperatures that help release volatile compounds into inhaled smoke. Cigarettes are known to be equipped with single-segment and multi-segment mouthpiece filters containing flavors such as menthol to modify the flavor of inhaled smoke.

Several smoking products are known in the prior art in which an aerosol-generating substrate, such as a tobacco substrate, is heated rather than burned. Such products may be marked with the term "aerosol generating products". Examples of systems that use products that generate an aerosol include systems that heat a substrate that contains tobacco above 200 degrees Celsius to form an aerosol that contains tobacco. Typically, in such aerosol-generating heating products, the respirable aerosol is generated by the transfer of heat from the heat source to the substrate or aerosol-forming material, which may be located within, around, or downstream of the heat source. During use of an aerosol-generating product, volatile compounds are released from the aerosol-generating substrate by heat transfer from the heat source and into the air drawn through the product. As the released compounds cool, they condense to form an aerosol that is inhaled by the user.

For example, in the manufacture of these smoking products, the tobacco substrate is usually heated or dried to remove water. During this heating or drying step, volatile compounds such as flavorings are removed from the tobacco substrate, altering the flavor of the finished smoking product. At this time, flavoring agents are sprayed directly onto the dried tobacco substrate. This method is called "top filling". This method is complicated,

Because the dosage and final concentration of the flavoring substance on the tobacco substrate may depend on environmental conditions and the design of the spraying device.

In addition, the flavoring substance may migrate or be released from the tobacco substrate during storage. All these factors can lead to undesirable variability in the taste of the product.

It is desirable to improve the homogeneity of the taste of the smoking product and the storage stability of flavorings added to the tobacco substrate (tobacco rod or aerosol-generating substrate).

Smoking compositions comprising a tobacco material with a flavoring delivery system described herein may be used in conventional combustible smoking products or in the aerosol generating substrate of aerosol generating smoking products. Flavoring delivery systems can provide smoking products with a predictable and consistent release of flavoring. This is particularly useful in combination with aerosol generating substrates that are heated during the preparation of the aerosol generating substrate.

As described herein, a smoking composition includes a flavoring delivery system and a tobacco material. The flavoring delivery system includes a flavoring material and a first wax material that forms the core of the wax material and a different second wax material that encapsulates the core.

Preferably, the first wax material has a melting point of about 100 degrees Celsius or higher. The flavoring material can be a hydrophobic liquid. The tobacco material is preferably homogenized tobacco or molded leaf tobacco that forms the aerosol generating substrate.

Various aspects of smoking compositions comprising tobacco material with a flavoring delivery system described herein may have one or more advantages over standard tobacco compositions. For example, flavoring delivery systems provide an improved flavoring experience compared to tobacco compositions that do not contain a flavoring delivery system. The wax material does not pour out or change the notes of the flavoring substance of the tobacco composition. The wax materials encapsulate the flavoring material to protect the flavoring material during the manufacture and storage of the smoking product that includes these tobacco compositions, and also predictably release the flavoring material during use of the smoking product. Combining the flavoring delivery system with the tobacco material to form the smoking composition also ensures uniform distribution of the flavoring material in the smoking composition. Flavoring delivery systems can replace or enhance tobacco flavoring notes that have been modified during the manufacture of the aerosol generating substrate. In addition, the outer wax coating or shell that surrounds or encapsulates the flavoring substance and the inner wax core can be a sacrificial layer that can perform a heat dissipation function, further protecting the core from release of the flavoring material during manufacture or storage of the smoking composition. Additional advantages of one or more aspects of the flavoring delivery system described herein will become apparent to those skilled in the art after reading and understanding the present invention.

The term "wax material" refers to natural or synthetic wax products that are hydrophobic and can transition to a molten liquid state (drop point) at temperatures below 200 degrees Celsius and are virtually free of ash-forming compounds.

The term "flavoring" or "flavoring substance" refers to organoleptic compounds, compositions or materials that change the taste or aroma characteristics of the tobacco substrate during its consumption.

The term "smoking product" includes cigarettes, cigars, cigarillos and other products in which smoking material, such as tobacco, is ignited and burned to produce smoke. The term "smoking article" also includes articles in which the smoking composition does not burn, such as, but not limited to, smoking articles that directly or indirectly heat the smoking composition without igniting or burning the smoking composition, or smoking articles in which smoking does not burn or heat, and air flow or a chemical reaction is used to deliver nicotine, flavoring compounds, or other materials from the tobacco substrate.

As used herein, the term "smoke" or "inhaled smoke" is used to describe the aerosol produced by heating or burning the tobacco substrate of a smoking product. An aerosol formed by a smoking product can be, for example, smoke, which

SO is produced by combustible smoking products, such as cigarettes, or aerosols produced by non-combustible smoking products, such as smoking products that are heated or smoking products that are not heated.

As used herein, the term "atomization" refers to the process by which a liquid, which may contain a molten material, a solution, an emulsion, or a combination thereof, is forced to flow through one or more orifices in an atomizer and is separated into droplets or particles.

The present invention provides smoking compositions containing tobacco material with a flavoring delivery system for smoking products. The flavoring delivery system comprises a flavoring material and a first wax material forming a core.

The first wax material encapsulates the flavoring material. A second waxy material surrounds the core and forms an encapsulated core or double-encapsulated flavoring material. The second wax material is a wax material different from the first wax material.

The flavoring delivery system described herein provides an improved way to incorporate flavors into a smoking product. The types of flavoring used in smoking products are usually relatively volatile, making it difficult to maintain acceptable levels of flavoring in smoking products during manufacture and storage. Volatile flavors can also mix into other parts of the smoking product and can adversely affect the performance of other components of the smoking product, such as any sorbents located inside the filter.

The flavoring delivery system can controllably release the flavoring agent or flavoring into the environment by increasing the temperature of the environment. A second waxy material forms a shell around the core. In some embodiments, the second wax material has a melting (dropping) temperature that exceeds the melting (dropping) temperature of the first wax material. In some embodiments, the second wax material has a melting (dropping) temperature that is substantially equal to the melting (dropping) temperature of the first wax material. Preferably, the second wax material has a melting (dropping) temperature that is lower than the melting (dropping) temperature of the first wax material. The melting (dropping) temperature can be determined using the standard test method for determining the dropping temperature of waxes known from the ABTM 03954-94(2010) standard.

The flavoring agent or flavoring may be dispersed or incorporated into the first wax material or contained within the first wax material. If they are dispersed or incorporated into the wax material, this is generally referred to as a matrix. If they are contained in a waxy material, this is usually referred to as a core-shell configuration. Thus, the core containing the first wax material and the flavoring agent may be a matrix or core-shell configuration. Preferably, the flavoring agent or flavoring agent is dispersed or incorporated into the first wax material. In many embodiments, the flavoring agent or flavoring agent is dispersed in the first wax material when the first wax material is in molten form. A nucleus is a particle (called a nucleus particle) that can be shaped in any applicable way. Preferably, the core particle is formed by atomization, such as spray cooling. Spray cooling provides a more uniform particle size than, for example, traditional spray drying.

In addition, spray cooling reduces the amount of heat that is supplied to the flavoring material, thus reducing losses due to evaporation or undesirable changes in the flavoring material. Spray cooling is preferably carried out with an inert gas, such as carbon dioxide or nitrogen, to further reduce conversion or undesirable changes in the flavoring material.

The core particle can then be encapsulated with a second wax material to form an encapsulated core. The core particle may be dispersed in a second wax material. Preferably, the core particle is dispersed in the second wax material when the second wax material is in molten form. The encapsulated core particle may be formed in any suitable manner. Preferably, the encapsulated core particle is formed by pulverization, such as spray cooling, as described above.

Applicable wax materials are selected from the group consisting of natural and synthetic waxes and mixtures thereof. Natural waxes are obtained from animals, plants, minerals and oil.

Animal waxes include, for example, beeswax, china wax, lanolin,

From shellac and spermaceti wax, etc. Vegetable waxes include, for example, carnauba wax, candelilla wax, mirica wax, sugarcane wax, castor wax, esparto wax, japonica wax, jojoba wax, auricle wax, rice bran wax, soy wax, and the like. Mineral waxes include, for example, ceresine wax, montan wax, mountain wax, peat wax, and the like. Petroleum waxes include, for example, paraffin wax, petroleum jelly, microcrystalline wax, and the like. Synthetic waxes include, for example, polyethylene waxes, Fischer-Tropsch waxes, chemically modified waxes, substituted amide waxes, polymerized alpha-olefins, and the like.

Particularly applicable wax materials do not alter the flavoring of the tobacco substrate, have a suitable melting or dropping point, flash point, ignition point, polarity, and are safe to use. The flash point and ignition of wax materials is particularly important when the flavoring delivery system described herein is combined with tobacco and heated in the manufacture of the tobacco substrate. It is preferable to use wax materials having a flash point and ignition temperature that exceed the temperatures affecting the wax materials in the manufacturing process. The flash point is the lowest temperature at which a flame will ignite the vapors of the heated filler, while the ignition temperature is the lowest temperature at which the vapors ignite and burn for at least 2 seconds.

Examples of applicable waxes include polyethylene waxes, polyethylene glycol waxes or vegetable waxes.

Typical examples of polyethylene waxes are sold under the trade name

SECIBOST by the company 0 Siagiapi Ipiegpaio!i (Her. Switzerland. Typical examples of polyethylene glycol waxes are sold under the trade name SAKWOUMAH by the company Joom/Spetisai! Co., USA. Typical examples of vegetable waxes are sold under the trade name KEME/!. by the company I odeg5 StoKiIaap, the Netherlands.

Flavorings or flavoring substances can be liquid or solid flavoring substances (at room temperature, which is about 22 degrees

Celsius. and pressure to one atmosphere) and may include flavoring compositions, materials containing flavoring substances, and flavoring precursors. The flavoring may 60 include one or more natural flavorings, one or more synthetic flavorings, or a combination of natural and synthetic flavorings. Preferably, the flavoring substance is a liquid. Preferably, the flavoring substance is a hydrophobic liquid.

Hydrophobic liquid flavoring substance is usually able to dissolve in organic solvents, but slightly soluble in water. Preferably, this hydrophobic liquid flavoring substance is characterized by a Hildebrand solubility parameter of less than 30

MPa". The water incompatibility of most oily liquids can actually be expressed by the Hildebrand solubility parameter 5, which is usually below 25 MPa", while for water it is 48 MPa", and 15-16 MPa!? for alkanes. This the parameter provides an applicable scale of polarity, which correlates with the energy density of the cohesive bond of molecules. For spontaneous mixing to occur, it is necessary to maintain a minimum difference in the parameters of 6 mixing molecules. In the Handbook of Solubility Parameters (ed. A.E.M. Vagiop, SKS Rgez5,

Vossa Kapp, 1991) provides a list of values of 5 for many chemicals, as well as methods of calculating recommended group fractions that allow calculation of values of b for complex chemical structures.

Flavorings or flavoring substances refer to a variety of flavoring materials of natural or synthetic origin. They include single compounds and mixtures. Preferably, the flavoring or flavorings on the substance have flavoring properties that improve the sensation of a non-combustible smoking product to provide, for example, a sensation similar to that of smoking a combustible smoking product. For example, a flavoring or flavoring agent can improve flavoring properties such as mouthfeel and balance. Balance in the general sense is known as the overall harmony of the flavoring substance, which is more "rich" without the dominance of individual sensory features. The degree of mouth filling is described as the perception of saturation and volume in the mouth and throat of the consumer.

Suitable flavoring agents and flavors include, but are not limited to, any natural or synthetic flavoring agent or flavor such as tobacco, smoke, menthol, mint (such as peppermint and spearmint), chocolate, licorice, citrus and other fruit aromas, gamma-octalactone, vanillin, ethylvanillin,

From breath fresheners, spicy flavoring agents such as cinnamon, methyl salicylate, linalool, bergamot oil, geranium oil, lemon oil, ginger oil, etc.

Other suitable flavoring agents and flavors may include flavoring compounds selected from the group consisting of an acid, an alcohol, an ester, an aldehyde, a ketone, a pyrazine, combinations or mixtures thereof, and the like. Suitable flavoring compounds may be selected, for example, from the group consisting of phenylacetic acid, solapone, megastigmatrisnone, 2-heptanone, benzyl alcohol, cis-3-hexenyl acetate, valeric acid, valeric aldehyde, ester, terpene, sesquiterpene, nutkatone, maltol, damascenone, pyrazine, lactone, anethole, iso-5 valeric acid, their combinations, etc.

Further specific examples of flavoring substances can be found in modern literature, for example, in the book Repite apa Briamoig SPpPetis!5. 1969, author 5. Agsiapaeg, Mopisiaig M.9U. (USA);

Uasorv, map Mozigapa So., Ips. They are well known to specialists in the field of aromatization, that is, adding a smell or taste to a product.

In some embodiments, the flavoring agent is a highly effective flavoring agent and is typically used in concentrations that result in less than 200 parts per million in aerosol or inhaled smoke. Examples of such flavoring agents are key tobacco flavoring compounds such as beta-damascenone, 2-ethyl-3,5-dimethylpyrazine, phenylacetaldehyde, guaiacol and furaneol. Humans can perceive other aromas only at higher concentration levels. These flavorants, referred to herein as low-efficiency flavorants, are typically used in concentrations that result in an order of magnitude greater amount of flavorant being released into the aerosol or inhaled smoke. Suitable low-impact flavorings include, but are not limited to, natural or synthetic menthol, peppermint, spearmint, coffee, tea, spices (such as cinnamon, cloves, and ginger), cocoa, vanilla, fruit flavorings, chocolate, eucalyptus, geranium, eugenol and linalool.

In preferred embodiments, the first wax material of the flavoring delivery system has a melting point of about 100 degrees

Celsius or above or about 120 degrees Celsius or above or about 140 degrees

Celsius or higher, or about 150 degrees Celsius or higher. In many embodiments, the first wax material has a melting point in the range of about

100 degrees Celsius to 150 degrees Celsius or from about 100 degrees Celsius to about 140 degrees Celsius. In many embodiments, the first wax material has a melting point no greater than about 200 degrees Celsius.

In preferred embodiments, the second wax material of the flavoring delivery system has a melting point of approximately 100 degrees

Celsius or less or about 90 degrees Celsius or less or about 80 degrees

Celsius or less, or about 70 degrees Celsius or less. In many embodiments, the second wax material has a melting point in the range of about 50 degrees Celsius to about 100 degrees Celsius, or about 50 degrees Celsius to about 80 degrees Celsius. In many embodiments, the second wax material has a melting point of about 40 degrees Celsius.

In preferred embodiments, the first wax material has a higher melting point than the second wax material. In some embodiments, the first wax material has a higher melting point that is about 30 degrees, or at least 40 degrees, or at least 50 degrees above the melting point of the second wax material. The flavoring substance is released from the flavoring delivery system when the first wax material is heated above its melting point. Preferably, the first and second wax materials are selected with different melting points, resulting in little or no melting of the first wax core material when the second wax material is used.

The flavoring material may be present in the core in any applicable amount. In many embodiments, the flavoring agent is present in the core in an amount of at least about 5 wt. 95. In many embodiments, the flavoring agent is present in the core in an amount less than about 50 wt. 95. In many embodiments, the flavoring agent is present in the core in an amount of from about 5 to about 50 wt. 95, or from about 5 to about 35 wt. 95, or from about 10 to about 30 wt. b.

The use of the flavoring delivery system described herein to provide flavoring within a smoking article advantageously reduces the loss of flavoring during storage in order to retain a greater proportion of flavoring in

From smoking products. Therefore, the flavoring delivery system can deliver a more saturated flavoring to the inhaled smoke. Because the loss of flavoring is reduced, less flavoring can be included in each smoking product, while providing the same flavoring effect as is provided in modern smoking products.

The core may have any applicable particle size or largest transverse dimension.

In many embodiments, the core has a particle size of about less than 30 micrometers or about less than 20 micrometers. In many embodiments, the core has a particle size that is greater than about 1 micrometer or greater than about 5 micrometers. In many embodiments, the core has a particle size in the range of from about 1 to about 30 micrometers, or from about 5 to about 25 micrometers, or from about 5 to about 20 micrometers.

The encapsulated core may have any applicable particle size or maximum transverse dimension. In many embodiments, the encapsulated core has a particle size of less than about 250 micrometers or less than about 200 micrometers. In many embodiments, the encapsulated core has a particle size greater than about 25 micrometers or greater than about 50 micrometers. In many embodiments, the encapsulated core has a particle size in the range of from about 25 to about 300 micrometers, or from about 25 to about 250 micrometers, or from about 50 to about 200 micrometers.

The core may be combined with the first wax material in any applicable amount to form an encapsulated core particle or flavoring delivery system. In many embodiments, the core represents at least about 1 wt. 9o from the total weight of the encapsulated core particle. In many embodiments, the core is at least about 5 wt. 95 of the total weight of the encapsulated core particle. In many embodiments, the core is less than about 50 wt. 95 of the total weight of the encapsulated core particle. In many embodiments, the core represents a range of from about 1 to about 50 wt.90 of the total weight of the encapsulated core particle, or from about 5 to about 50 wt. 95 of the total weight of the encapsulated core particle. or from about 10 to about 35 wt. 95 of the total weight of the encapsulated core particle.

The flavoring delivery system is combined with the tobacco material to form a tobacco composition or smoking composition that provides a stable and predictable release of flavoring as the tobacco composition or smoking composition is heated to a temperature at which the waxy material melts and releases the flavoring into inhaled smoke or aerosol for use. The flavoring delivery system can be combined with cut tobacco to form a tobacco composition or smoking composition for use with traditional combustible smoking products. Preferably, the flavoring delivery system can be combined with reconstituted or homogenized tobacco to form a tobacco composition or smoking composition for use with aerosol generating products. Preferably, homogenized tobacco is formed leaf tobacco.

Smoking articles may contain an aerosol-generating substrate that is assembled, often with other components, in the form of a rod. As a rule, such a rod has such a shape and dimensions that ensure the possibility of its insertion into an aerosol-generating device that contains a heating element for heating the aerosol-generating substrate. An "aerosol-forming substrate" or "aerosol-generating substrate" in the context of this document is a type of smoking composition that can be used to produce an aerosol in an aerosol-generating device. The aerosol generating substrate can release the aroma compound when heated. The aerosol-generating substrate can contain both liquid and solid components. The aerosol-generating substrate may contain tobacco material and the described flavoring delivery system, where the flavoring is released from the substrate upon heating. Preferably, the aerosol-generating substrate does not burn.

The aerosol-generating substrate may additionally contain an aerosol-forming substance.

Examples of suitable substances for aerosol formation are glycerin and propylene glycol.

Optionally, the aerosol-generating substrate may be provided on or incorporated into the carrier, and the carrier may be in the form of powder, granules, balls, granules, thin tubes, strips, or sheets. The aerosol-generating substrate can be applied to the surface of the carrier in the form of, for example, a sheet, foam, gel or suspension. The aerosol generating substrate may be applied to the entire surface of the support or alternatively may be applied as

From a pattern to provide a non-uniform delivery of the flavoring substance during use.

Homogenized tobacco can be used to make an aerosol-generating substrate for use in smoking products that are heated in an aerosol-generating device. In this context, the term "homogenized tobacco" means a material formed by agglomeration of tobacco in the form of particles. Tobacco dust generated by grinding tobacco during transportation and manufacturing, leaf lamina, stalks and other tobacco waste that is very finely ground can be mixed with a binder to agglomerate the tobacco in the form of particles. Homogenized tobacco may contain other additives in addition to the flavoring composition or flavoring delivery composition, including, but not limited to, aerosolizing agents, plasticizers, wetting agents and non-tobacco fibers, fillers, aqueous and non-aqueous solvents, and combinations thereof. Homogenized tobacco can be molded, extruded or rolled. Several recovery methods are known from the prior art for the production of homogenized tobacco materials. They include, among other things, paper production processes of the type described, for example, in document O5 5724998; forming processes (sheet formation) related to the type described, for example, in document 5 5724998; dough recovery processes of the type described, for example, in document 5 3894544; and extrusion processes of the type described, for example, in document ЗВ 983928.

The flavoring delivery system can be incorporated into a tobacco material, such as a formed sheet tobacco substrate formed in the sheet forming process. This type of process is known as a sheet forming process and is used in the tobacco industry to produce reconstituted or homogenized tobacco for use in a conventional cigarette. Molded leaf tobacco substrates can be formed by combining homogenized tobacco powder with water, glycerin and other optional additives to form a suspension and combining the described flavoring delivery system in suspension. The slurry can then be formed and dried (heated) to remove the water and form the formed sheet tobacco substrate.

The process of forming the sheets can include the application of temperatures up to about 140 "C, for example, from about 90 "C to 140 "C. Accordingly, one or both of the wax materials of the flavoring delivery system are preferably stable at such temperatures.

Preferably, the first wax material of the core is stable at such temperatures as a result of which the flavoring substance is not released during the heating step in the process of forming the sheets. In many embodiments, the second wax material has a melting point that is substantially equal to the drying temperature in the drying step of the sheet forming process. In some embodiments, the second wax material has a melting temperature that is less than the drying temperature in the drying step of the sheet forming process. In these embodiments, at least a portion of the shell or second wax material is separated from the core upon melting and dispersed within the homogenized tobacco material.

Preferably, the first waxy material forming the core of the flavoring substance has a melting point that exceeds the temperature used to form the substrate of the molded leaf tobacco.

The organoleptic analysis of wax materials is carried out using the descriptive criterion "general organoleptic neutrality" to indicate differences in saturation.

Since organoleptic and psychological fatigue occurs after 7-8 samples, a balanced incomplete block plan (Viv) (BO 29842) was chosen for the evaluation test (ISO 8587).

Evaluation experts receive five samples per session in random order and must evaluate the samples according to the criterion. To achieve a sufficient level of accuracy, four sessions are conducted.

The results of this VIV assessment are presented in Table 2.

Several flavoring delivery systems are formed as follows: first, the flavoring is cooled by spraying a first wax material to form the core, and then the core is cooled by spraying a second wax material to form the encapsulated core or flavoring delivery system. In the table

The results of materials after sieving are presented.

These samples were then analyzed for particle size distribution, bulk density, and morphology.

The particle size distribution is measured by the laser diffraction method using the device

Maimegp Maziegvzileg 2000. The device for studying liquid dispersion "Nuygo MI" is used to measure particles that are dispersed in ethanol. After dispersing the samples in ethanol, the ultrasonic bath is turned on for three minutes to grind agglomerates.

Measurements begin after 1 minute. All samples are measured twice and average values are reported. Data interpretation is carried out according to the Fraunhofer theory.

Maevhieghieg grinds the agglomerates using an ultrasonic bath before measuring the particle size; the particle size measured by the laser diffraction method differs from the expected particle size of the sieved fractions. Sieving of samples does not destroy agglomerates and the sieved fractions actually consist of agglomerates and not single particle fractions.

In fig. 2 shows the particle size distributions of the core-shell samples from Examples 1-6 formed as a result of the double spray cooling process described above.

The bulk density of the core-shell samples from examples 1-6 is measured according to SIM IZO 697.

In fig. Volume densities are presented. In fig. 4-6 present images obtained using a scanning electron microscope (SEM), example 1 (Kemei! And 10 to C3610-95 arom.- 63-125 μm). In fig. 4 presents an overview image of particles according to example 1. Almost all particles have a spherical shape. In fig. 5 shows an enlarged image of the agglomerate. Larger particles indicate double-encapsulated particles and small particles indicate single-layer encapsulation. In fig. 6 shows an enlarged image 25 of a single particle with a particle size of approximately 80 µm. The surface is very smooth and does not contain capillaries or holes.

Flavor release from the flavor delivery system was then assessed. The flavoring delivery system described herein, which was formed as a result of spray cooling in two stages, was added to

From the suspension of the molded sheet before the formation of the substrate of molded sheet tobacco at a concentration of 95 (w/vgas. The molded sheet was formed according to the standard procedure for forming sheets, which includes a drying step at a temperature of approximately 100 "C. During the production of the molded sheet, nothing unusual was observed , indicating no or low loss of flavoring agent.Using the formed molded sheet, consumables (tobacco sticks) were produced for use in the aerosol generating substrate.

The release of the flavoring substance was analyzed according to the reference regime of intensive smoking according to the Ministry of Health Canada. The following two examples describe the successful release of flavoring ingredients by the described flavoring delivery system. For both examples, expressed in quantitative form, the flavoring ingredients cannot be detected in the aerosol of the consumable without the addition of the flavoring delivery system described herein.

Expressed in quantitative form the release of flavoring agent 3-ethylphenol, which uses a combination of Kemei! A/segidivy (35 95) with a particle size of 63-125 µm (see example 3) in a molded sheet of consumable material was approximately 14 ng per 12 puffs of intensive mode according to Health Canada.

Quantified release of pyrazine flavoring using a sunflower/segidivi wax combination (25 95) with a particle size of 63-

125 µm (see example 5), in a molded sheet of consumable was approximately 18 ng per 12 heavy duty puffs according to Health Canada.
