FIELD OF THE INVENTION The present disclosure relates to a aerosolisable product, containers in which are contained the aerosolisable product and to electronic vapour provision systems such as electronic delivery systems (e.g. e-cigarettes) incorporating said aerosolisable product.

BACKGROUND TO THE INVENTION

Electronic vapour provision systems such as e-cigarettes generally contain a reservoir of liquid which is to be vaporised, typically containing nicotine. When a user inhales on the device, a heater is activated to vaporise 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 vapour provision device a vapour 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 flavour in the mouth. These various aspects are described by users in terms of flavour, intensity/quality, impact, and irritation/smoothness. Each of these factors, and their balance, can strongly contribute to consumer acceptability of an e- cigarette. Providing means to optimise the overall vaping experience is therefore desirable to e-cigarette manufacturers. To address these requirements, most 'e-liquids' are imparted with flavour/aroma by adding in specific flavourants to the e-liquid. However, it is still considered that these substrates could be improved in terms of the flavour/aroma they provide.

The invention will now be described with reference to the following non-limiting example. Examples

Formulation

To prepare a flavoured liquid 500g of tobacco (Virginia) was smouldered alongside 500g 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 aerolisable 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 aerolisable material (propylene glycol).

Sample Analysis 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. vegetable glycerol 47% w/w

propylene glycol (smoke treated) 35% w/w

water 18% w/w

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. Liquid testing

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

Sample A - phenol levels significantly lower vs sample B Aerosol Testing

The below analytes were not detected within the aerosol formed from either sample (A or B):

acrolein, n-butyraldehyde, crotonaldehyde, glycolaldehyde, acetoin, 2,3-pentanedione, 2,3-hexanedione, and 2,3-heptanedione. User Testing

When each of Samples A and B are tested by a user panel they are found to provide a pleasant experience. Each of Samples A and B are found to provide an aerosol have flavour and aroma which is enhanced compared to a non-smoked product.
