Patent Application
20200253265
The present disclosure relates to an aerosolizable product, containers in which are contained the aerosolizable product and to electronic vapor provision systems such as electronic delivery systems (e.g. e-cigarettes) incorporating said aerosolizable product.
Electronic vapor provision systems such as e-cigarettes generally contain a reservoir of liquid which is to be vaporized, typically containing nicotine. When a user inhales on the device, a heater is activated to vaporize a small amount of liquid, which is therefore inhaled by the user.
The use of e-cigarettes in the UK has grown rapidly, and it has been estimated that there are now almost three million people using them in the UK.
One challenge faced in providing such systems is to provide from the vapor provision device a vapor to be inhaled which provides consumers with an acceptable experience. Some consumers may prefer an e-cigarette that generates an aerosol that closely ‘mimics’ smoke inhaled from a tobacco product such as a cigarette. Aerosols from e-cigarettes and smoke from tobacco products such as cigarettes provides to the user a complex chain of flavor in the mouth. These various aspects are described by users in terms of flavor, intensity/quality, impact, and irritation/smoothness. Each of these factors, and their balance, can strongly contribute to consumer acceptability of an e-cigarette. Providing ways to improve the overall vaping experience is therefore desirable to e-cigarette manufacturers. To address these requirements, most ‘e-liquids’ are imparted with flavor/aroma by adding in specific flavorants to the e-liquid. However, it is still considered that these substrates could be improved in terms of the flavor/aroma they provide.
In one aspect there is provided an aerosolizable product comprising an aerosol forming material, wherein the aerosol forming material is infused with smoke from tobacco.
In one aspect there is provided an aerosolizable product comprising an aerosol forming material, wherein the aerosol forming material is selected from polyhydric alcohols (such as glycerol, propylene glycol and triethylene glycol), esters (such as triethyl citrate and triacetin), high boiling point hydrocarbons, non-polyols (such as glycols, sorbitol and lactic acid), and mixtures thereof [preferably wherein the aerosol forming material is selected from glycerol, propylene glycol, and mixtures thereof]; and wherein the aerosol forming material is infused with smoke from a plant material.
The aerosol generating product preferably comprises aerosol forming material, and may be for example polyhydric alcohols, such as glycerol, propylene glycol and triethylene glycol, for example, or esters such as triethyl citrate or triacetin, or high boiling point hydrocarbons, or non-polyols, such as glycols, sorbitol or lactic acid, for example.

The above summary is not intended to describe each illustrated embodiment or every implementation of the subject matter hereof. The detailed description that follows more particularly exemplifies various embodiments.
As discussed herein the present disclosure provides an aerosolizable product comprising an aerosol forming material, wherein the aerosol forming material is infused with smoke from tobacco, and the present disclosure provides an aerosolizable product comprising an aerosol forming material, wherein the aerosol forming material is selected from polyhydric alcohols (such as glycerol, propylene glycol and triethylene glycol), esters (such as triethyl citrate and triacetin), high boiling point hydrocarbons, non-polyols (such as glycols, sorbitol and lactic acid), and mixtures thereof [preferably wherein the aerosol forming material is selected from glycerol, propylene glycol, and mixtures thereof]; and wherein the aerosol forming material is infused with smoke from a plant material.
We have found the flavor and/or aroma provided by an aerosol forming material in an aerosolizable product may be enhanced by subjecting the aerosol forming material, such as glycerol, to smoke from a plant material, and in particular smoke from tobacco. Various combinations of plant material may be used to generate the smoke, such as tobacco only, combinations of tobacco and wood, and wood only. The generated smoke is then contacted with the aerosol forming material, such as glycerol.

To prepare a flavored liquid 500 g of tobacco (Virginia) was smoldered alongside 500 g of a selected wood (oak) for a total of 4 hours. The created smoke was then separated into two samples. One sample was filtered in accordance with a method as described in WO2015/007742 and the other sample was not filtered. The smoke samples were then exposed to the selected aerosolizable material (propylene glycol).
Sample A was the sample treated in accordance with WO2015/007742. Sample B was the sample that was not passed through the filtration process before being exposed to the aerosolizable material (propylene glycol).
A series of analytical tests were required in order to quantify key compounds. The liquids were tested in respect of nicotine, water, glycerol, N-Nitrosonornicotine (NNN), N′-nitrosoanatabine (NAT), N-nitrosoanabasine (NAB), nicotine-derived nitrosamine ketone (NNK-also known as 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone), benzo(a)pyrene, toluene, phenol and propylene glycol. The aerosols were tested in respect of formaldehyde, acetaldehyde, acetone, propionaldehyde, isobutyraldehyde, methyl ethyl ketone, acetol, glyoxal, methylglyoxal, 2,3-butanedione, acrolein, n-butyraldehyde, crotonaldehyde, glycolaldehyde, acetoin, 2,3-pentanedione, 2,3-hexanedione, and 2,3-heptanedione.
For emission testing a Vype e-Tank device was filled using the following formulation matrix. The presence and levels of the carbonyls listed above 1 were tested for.
Devices containing samples A & B were then puffed on a linear smoke machine using a 80/3/30 regime. A total of 100 puffs were captured for both samples in 25 puff blocks. 3 reps per puff block were measured with an average obtained.
The below analytes were not detected within the liquid of either sample (A or B):
Nicotine, glycerol, NNN, NAT, NAB, and NNK.
It was also noted that
Sample A—benzo(a)pyrene (<LOD) vs sample B
Sample A—toluene (<LOD) vs sample B
