example 2

[0066] Example 2 : Formulation and analysis of PDO-based compositions

[0067] Proceed in the same manner as Example 1, but replace the plant-derived propylene glycol with 1,3-propanediol manufactured by DuPont&Tate&Lyle LLC under Cat. No. Provided by Propanediol.

[0068] result :

[0069] Under the analytical conditions (sensitivity 0.5 ng / g), no trace of propylene oxide was detected, nor traces of dipropylene glycol and tripropylene glycol.

[0070] The biogenic carbon content of the mixture is equal to 99.7%.

[0071] (Contrast) Example 3 : Formulation and Analysis of Synthetic Propylene Glycol Based Compositions

[0072] Proceed in the same manner as Example 1, but replace the plant-derived propylene glycol with synthetic propylene glycol, manufactured by Dow under Cat. No. Provided by Propylene glycol, USP grade.

[0073] result :

[0074] Under the analytical conditions (sensitivity 0.5 ng / g), no traces of dipropylene glycol and tripropylene glycol wer...

example 4

[0077] Example 4 : Formulation and analysis of glycerol-free compositions

[0078] Proceed in the same manner as Example 1, but replace plant-derived glycerol and propylene glycol with plant-derived PDO according to Example 2.

[0079] result :

[0080] Under the analytical conditions (sensitivity 0.5 ng / g), no trace of propylene oxide was detected, nor traces of dipropylene glycol and tripropylene glycol.

[0081] The biogenic carbon content of the mixture is equal to 99.8%.

example 5

[0082] Example 5 : Assessing the efficacy of different e-liquids

[0083] By providing a trademarked And the model is eCab TM (December 2013 model) panel of 10 smokers to evaluate the e-liquid compositions formulated in Examples 1 to 4. Each reservoir is filled with an equal amount of e-liquid (1ml).

[0084] In this way, each group member inhales 8 times continuously every 20 seconds according to the blind test method, and there is a heating time of 2 seconds before each inhalation. Evaluations are based on scoring on a scale of 1 to 10 for vapor density criteria and perceived aroma intensity criteria. Each panelist transitioned from one product to another as follows: 5 minutes after the last inhalation, the panelist rinsed with 2 glasses of 100 ml of water and then drank 50 ml of water. There was a 10-minute break between each assessment.

[0085] The average results obtained are compiled in the table below:

[0086]

[0087] Apparently, plant-derived propylene g...

Abstract

The invention relates to the use of a composition containing 1, 3-propanediol as an electronic cigarette liquid. The invention also relates to a liquid composition for electronic cigarettes comprising 1, 3-propanediol, as well as at least one compound selected from nicotine, a nicotine substitute and an aroma. The invention also relates to an electronic cigarette containing said composition.

Description

technical field [0001] The present invention relates to the use of a composition containing 1,3-propanediol as an electronic cigarette liquid. The present invention also relates to a liquid composition for electronic cigarettes, comprising 1,3-propanediol and nicotine and / or at least one fragrance, and electronic cigarettes comprising the composition. Background technique [0002] The electronic cigarette market is currently developing very rapidly because it enables consumers to maintain the habit of smoking without being poisoned by harmful substances contained in cigarettes. [0003] Electronic cigarettes (e-cigarettes) work by electricity rather than combustion. E-cigarettes produce a mist of fine particles, often called artificial vapor or artificial smoke, which looks a lot like the smoke from burning tobacco. The vapor may be flavored (tobacco, mint, fruit, chocolate, etc.) and nicotine-free. In e-cigarettes that are regularly manufactured and used, according to th...
