Embodiment 1

[0070] Example 1 : Preparation and analysis of 1,3-butanediol-based and glycerol-based compositions

[0071] Precisely 10.00 kg of 1,3-butanediol (sold for example by the company Kyowa under the name 1,3-butanediol, cosmetic grade), 1.00 kg of vegetable glycerin (sold by the company Oleon under the number Glycérine 4810, USP and PE pharmacopoeia grade), 450.0g of apple fruit flavor (sold by Safisis under the code PT 128) and 114.50g of plant nicotine (sold by Alchem ​​International under the code Nicotine Free Base, pharmaceutical grade nicotine >99%) in a Mix precisely in a mechanically stirred glass mixture. Stirring of the mixture (50 rpm) was maintained for 20 minutes. A 500 g sample was taken for analysis. The measurement of the kinematic viscosity is then carried out at 25° C. by means of a Houillon viscometer tube m 943 with a coefficient of 0.35051.

[0072] result :

[0073] The viscosity at 20°C is equal to 65.2mm 2 / s.

Embodiment 2

[0074] Example 2 Preparation and analysis of glycerol-free compositions

[0075] The same procedure as Example 1 was followed, but 1 kg of 1,3-butanediol (supplied by Kyowa) according to Example 1 was used instead of glycerin of vegetable origin. Viscosity measurement was then performed under the same conditions as in Example 1.

[0076] result :

[0077] The viscosity at 20°C is equal to 101.2mm 2 / s.

Embodiment 3

[0078] Example 3 (Comparison): Evaluation of the effectiveness of different e-liquids

[0079] According to the same step as in Example 1, but with the synthetic propylene glycol (No. Propylene glycol, USP grade) instead of 1,3-butanediol. Viscosity measurements were then carried out at 20°C.

[0080] result :

[0081] The viscosity at 20°C is equal to 59.2mm 2 / s.

[0082] In conclusion, it can be determined that e-liquids based on 1,3-butanediol and associated or not with glycerol (Examples 1 and 2) have comparable viscosities to conventional e-liquids (Example 3).

Abstract

The invention relates to the use of a composition containing a polyol that comprises 4 to 8 carbon atoms and 2 hydroxyl functions, as a liquid for electronic cigarettes. The invention further relates to a liquid composition for electronic cigarettes, containing a polyol that comprises 4 to 8 carbon atoms and 2 hydroxyl functions, as well as at least one compound selected from among 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 comprising long-chain polyols as a liquid for electronic cigarettes. A subject of the invention is also a liquid composition for electronic cigarettes comprising a polyol together with nicotine and / or at least one flavorant and an electronic cigarette with an associated device comprising this composition. Background technique [0002] The e-cigarette market is currently experiencing significant development as e-cigarettes allow users to maintain the routine habits associated with the use of cigarettes without the harmful effects of the harmful substances they contain. [0003] E-cigarettes work through electricity rather than combustion. It produces a fine particle mist commonly referred to as vapor or artificial smoke, which is visually similar to the smoke produced by burning tobacco. This vapor may be aromatized (tobacco, mint, fruit, chocolate, etc.) and contain nicotine or not. In proper...
