Description

[0001] An Aerosol Generation Consumable

[0002] The present disclosure relates to a composition comprising one or more somatosensory compounds and an aerosol generation consumable comprising such a composition. The present disclosure further relates to a device comprising such a consumable and the use of such somatosensory compounds.

[0003] Background

[0004] Aerosol generation devices (or electronic cigarettes or "e-cigarettes") have been developed as an alternative to traditional cigarettes as a means for volatilizing active components for inhalation without combustion, while at the same time providing the user with an oral experience similar to that of traditional cigarette smoking.

[0005] Such aerosol generation devices typically comprise consumables which comprise compositions that can be volatilized and inhaled as a vapour by a user (such as an adult vaper). There are further products, such as nicotine oral delivery products, which provide different ways of administering nicotine to a user. Nicotine oral delivery products typically take the form of a nicotine composition enclosed within a pouch.

[0006] It is common for both types of compositions to comprise a flavour additive with the aim of providing an enhanced user satisfaction. Flavour additives may be added to provide a flavour and / or smell effect to the user. However, for some users, vapour containing flavour additives is overpowering and undesirable.

[0007] The overall sensory experience of inhaling vapour is more than just the flavour provided to the user. It may be preferable to provide a different effect to the user, other than flavour and / or smell.

[0008] There is a need to provide aerosol generation consumables that can provide a desirable sensory effect experience, i.e., for example by providing an improved throat sensation.

[0009] It is one aim of the present invention, amongst others, to provide an aerosol generation consumable that addresses at least one disadvantage of the prior art, whether identified here or elsewhere, or to provide an alternative to existing aerosol generation consumables.

[0017] Unless otherwise stated, the following terms used in the specification and claims have the meanings set out below.

[0018] As used herein, the term “aerosol precursor material”, “vapour precursor material” or “vaporizable material” are used synonymously and may refer to a material and / or composition, which may for example comprise nicotine or tobacco and a vaporising agent. The aerosol precursor material is configured to release an aerosol when heated or otherwise mechanically stimulated (such as by vibrations). Tobacco may take the form of various materials such as shredded tobacco, granulated tobacco, tobacco leaf and / or reconstituted tobacco. Typically, tobacco may comprise a small amount of vaporising agent, such as glycerol. Nicotine may be in the form of nicotine salts. Suitable vaporising agents include: a polyol such as sorbitol, glycerol, and glycols like propylene glycol or triethylene glycol; a non-polyol such as monohydric alcohols, acids such as lactic acid, glycerol derivatives, esters such as triacetin, triethylene glycol diacetate, triethyl citrate, glycerin or vegetable glycerin. Preferably, the vaporising agent comprises glycerol and / or glycol. In some examples, the aerosol precursor material is substantially a liquid or a gel that holds or comprises one or more solid particles, such as tobacco particles extracted from tobacco materials or suspended in a solution or gel.

[0019] The aerosol precursor material may comprise cellulose-based sheet material or paper, and a vaporising agent.

[0020] An aerosol generation device is configured to aerosolise an aerosol precursor material without combustion in order to facilitate delivery of an aerosol to a user. Furthermore, and as is common in the technical field, the terms “vapour” and “aerosol”, and related terms such as “vaporize”, “volatilize” and “aerosolise”, may generally be used interchangeably.

[0021] As used herein, the term “aerosol generation device” is synonymous with “aerosol generating device” or “device” and may include a device configured to heat an aerosol precursor material and deliver an aerosol to a user, typically without combusting the aerosol precursor material. The device may be portable. “Portable” may refer to the device being for use when held by a user. The device may be adapted to generate a variable amount of aerosol, which can be controlled by a user input.

[0022] As used herein, the term “aerosol” may include a suspension of vaporizable material as one or more of: solid particles; liquid droplets; gas. Said suspension may be in a gas including air. Aerosol herein may generally refer to / include a vapour. Aerosol may include one or more components of the vaporizable material.

[0023] As used herein, the term “somatosensory compound(s)” may refer to compounds which provide a somatosensory effect to the user. As used herein, the term “somatosensory effect” refers to effects such as warming, cooling, fizzing, numbing, pungency, astringency, pain, itching, touch, and pressure and / or kokumi. The term “somatosensory effect” does not include flavour and / or smell.

[0024] The composition comprises aerosol precursor material and one or more somatosensory compounds. The one or more somatosensory compounds may be an isocyanate or an aldehyde somatosensory compound, or a mixture thereof.

Suitably, the flavour additive may have a higher flavour and / or smell value than the somatosensory effect value thereof, as measured on the labelled magnitude scale (LMS), discussed in detail below. Preferably, the composition does not comprise a flavour additive that has a higher flavour and / or smell value than the somatosensory effect thereof, as measured on the labelled magnitude scale (LMS). By “higher flavour and / or smell effect than the somatosensory effect thereof” is meant that the flavour and / or smell effect provided by the compounds to the user is stronger than the somatosensory effect of said compounds. For example, the ratio of the flavour and / or smell labelled magnitude scale value to the somatosensory labelled magnitude scale value of the flavour additive may be greater than 1 :1 , such as 1.5:1 , such as 2: 1 , such as 3:1 , such as 4:1 , such as 5:1 , such as 6:1 , such as 7:1 such as 8:1 , such as 9:1 , such as 10:1 , such as 11 :1 , or even 12:1 The presence of such a flavour additive may disturb the somatosensory effect of the somatosensory compound on the user.

[0069] Definitions

[0070] The term "alkyl" as used herein, refers to saturated, straight- or branched-chain hydrocarbon radicals derived by removal of a single hydrogen atom from an aliphatic moiety. An alkyl group is preferably a “C1-20 alkyl group”, that is an alkyl group that is a straight or branched chain with 1 to 20 carbons. The alkyl group therefore has 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 , 12, 13, 14, 15, 16, 17, 18, 19 or 20 carbon atoms. Preferably, an alkyl group is a C1-15 alkyl, preferably a C1-12 alkyl, more preferably a C1-10 alkyl, even more preferably a C1-8 alkyl, even more preferably a C1-6 alkyl group. Specifically, examples of “C1-20 alkyl group" include methyl group, ethyl group, n-propyl group, isopropyl group, n-butyl group, iso-butyl group, sec-butyl group, tert-butyl group, secpentyl, iso-pentyl, n-pentyl group, neopentyl, n-hexyl group, sec-hexyl, n-heptyl group, n-octyl group, n-nonyl group, n-decyl group, n-undecyl group, n-dodecyl group, n- tridecyl group, n-tetradecyl group, n-pentadecyl group, n-hexadecyl group, n- heptadecyl group, n-octadecyl group, n-nonadecyl group, n-eicosyl group, 1 ,1- dimethylpropyl group, 1 ,2-dimethylpropyl group, 2,2-dimethylpropyl group, 1- ethylpropyl group, n-hexyl group, 1-ethyl-2-methylpropyl group, 1 , 1 ,2-trimethylpropyl group, 1 -ethylbutyl group, 1 -methylbutyl group, 2-methylbutyl group, 1 ,1 -dimethylbutyl group, 1 ,2-dimethylbutyl group, 2,2-dimethylbutyl group, 1 ,3-dimethylbutyl group, 2,3- dimethylbutyl group, 2-ethylbutyl group, 2-methylpentyl group, 3-methylpentyl group and the like. The term “linear” as used herein refers to a saturated or unsaturated straight chain, which does not contain any branched or cyclic groups. The term “cyclic group” refers to both aromatic and non-aromatic ring systems.

[0071] The term “unsaturated” means a moiety that has one or more double and / or triple bonds.

[0072] Throughout this specification, the term “comprising” or “comprises” means including the component(s) specified but not to the exclusion of the presence of other components. The term “consisting essentially of” or “consists essentially of” means including the components specified but excluding other components except for materials present as impurities, unavoidable materials present as a result of processes used to provide the components, and components added for a purpose other than achieving the technical effect of the invention. Typically, when referring to compositions, a composition consisting essentially of a set of components will comprise less than 5% by weight, typically less than 3% by weight, more typically less than 1% by weight of non-specified components.

[0073] For the avoidance of doubt, wherein amounts of components in a composition are described in wt%, this means the weight percentage of the specified component in relation to the whole composition referred to. For example, “wherein the total amount of the one or more somatosensory compounds present in the composition may be from 1 to 15 wt.% of the total composition” means that 1 wt% to 15 wt% of the total composition is provided by the one or more somatosensory compounds.

[0075] Assessment of the somatosensory experience of compounds

[0076] A standard method for the assessment of somatosensory effect, flavours and smells was used to assess the sensorial experience of liquid compositions in an objective manner.

[0077] Through this method, the sensory characteristics of all products would be determined by a trained sensory panel. The assessors included in the panel would be selected based on their sensory acuity and descriptive ability. Example 1

[0078] Description of the methodology

[0079] A 20 mg undiluted solution of a somatosensory compound was added to an inhaler. For testing the somatosensory compound ethyl isothiocyanate, 20 mg of a propylene glycol solution comprising 1 wt% of ethyl isothiocyanate was used.

[0080] The solution was added to the inside wall of the inhaler, and both ends of the inhaler were closed by non-woven fabric filters. The solution was heated at 60°C within the inhaler and inhaled by the panel as a vapour.

[0081] A Labelled Magnitude Scale (LMS) was used to determine the strength of the sensorial effect on the panel.

[0082] The trained sensory evaluation panel was asked to mark the intensity of sensation (somatosensation / flavour and / or smell) of each sample.

[0083] Sensory evaluation result:

[0084] A list of the somatosensory compounds and comparative compounds tested is set out in Table 1 below, along with the results of the test.

[0085] Example 2

[0086] A 4 mg sample of 2-ethyl-2-hexenal was added to 250 mg of shredded tobacco (Burley 100%, no perfume added after shredding). The shredded tobacco was added into a plastic tube and both ends were closed by non-woven fabric filters. The tube was then heated to 60 °C and the resulting vapour was inhaled by the panel.

[0087] A plastic tube filled with 250 mg of shredded tobacco (Burley 100%, no perfume added after shredding) was also heated to 60 °C and the resulting vapour was inhaled by the panel.

[0088] Sensory evaluation result:

[0089] In the sample comprising 2-ethyl-2-hexenal, the panel perceived a somatosensation change compared to the sample comprising shredded tobacco without 2-ethyl-2- hexanal. The panel did not perceive a change in the flavour / smell of the vapour inhaled from the sample comprising 2-ethyl-2-hexenal, compared to the vapour sample without 2-ethyl-2-hexanal.
