Use of a composition containing 1,3-propanediol as e-liquid

a technology of 1,3-propanediol and e-liquid, which is applied in the field of use of a composition containing 1,3-propanediol as e-liquid, can solve the problems of affecting the taste of the smoke, the quality of the smoke emitted is far from being appropriate in terms of vapor density, and the longevity of the heating resistor is quickly fouled, so as to improve the bioavailability of nicotine, improve the throat hit sensation, and reinforce the aromatic power

Benefits of technology

[0028]It also relates to a use of 1,3-propanediol in an electronic cigarette liquid which may or may not contain nicotine, in order to improve the throat hit felt by a user of said liquid and/or the ease of inhaling the vapor produced by said liquid and to a use of 1,3-propanediol in an electronic cigarette liquid containing nicotine, in order to improve the bioavail...

Problems solved by technology

However, this objective is achieved at the expense of the longevity of the heating resistors which very rapidly become fouled.
In addition, the quality of the smoke emitted is far from being appropriate in terms of vapor density, and the organoleptic properties of the liquids are greatly modified, because the release of the aromas is less immediate in the absence of propylene glycol.
But again, the impact of a high water content radically modifies the quality of the vapor released and leads to excessive corrosion of the materials as well as to rapid and excessive consumption of the e-liquid (faster vaporization).
Finally, another problem connected with the exclusive use of glycerol lies in the fact that this compound is clearly...

Preparation and Analysis of a PDO-Based Composition

[0060]The procedure used is identical to that of Example 1, except that the propylene glycol of plant origin is replaced with 1,3-propanediol supplied by the company DuPont & Tate & Lyle LLC under the reference Zemea® Propanediol.

Results:

[0061]Under the conditions of analysis (sensitivity 0.5 ng / g), no trace of propylene oxide or of di- and tripropylene glycols is detected.

[0062]The content of bio-sourced carbon of the mixture is equal to 99.7%.

Preparation and Analysis of a Glycerol-Free Composition

[0067]The procedure used is identical to that of Example 1, except that the propylene glycol and the glycerol of plant origin are replaced with PDO of plant origin according to Example 2.

Results:

[0068]Under the conditions of analysis (sensitivity 0.5 ng / g), no trace of propylene oxide or of di- and tripropylene glycols is detected.

[0069]The content of bio-sourced carbon of the mixture is equal to 99.8%.

Evaluation of the Efficacy of Various e-Liquids

[0070]The e-liquid compositions prepared in Examples 1 to 4 are evaluated by a trained panel of 10 persons provided with a cigarette of brand Joytech™ and of model eCab™ (December 2013 model). Each reservoir is filled with the same amount of e-liquid (1 mL).

[0071]Under blind conditions, each panelist thus performs a test based on 8 successive drags spaced apart by 20 seconds and each induced by heating for 2 seconds. The evaluation is based on scoring the criteria of vapor density and of aromatic power perceived on a scale from 1 to 10. The switch from one product to another is carried out by each panelist as follows: 5 minutes after the last inhalation, the panelist rinses his mouth with 2 glasses of water of 100 mL each and then drinks 50 mL of water. A rest period of 10 minutes separates the evaluations.

[0072]The averaged results obtained are collected in the following table:

Abstract

A composition containing 1,3-propanediol for use as electronic cigarette liquid. A liquid composition for an electronic cigarette, including 1,3-propanediol, as well as at least one compound selected from nicotine, a nicotine substitute, and an aroma, and an electronic cigarette containing this composition.

Description

TECHNICAL FIELD[0001]The present invention relates to the use of a composition containing 1,3-propanediol as electronic cigarette liquid. It also relates to a liquid composition for an electronic cigarette including 1,3-propanediol as well as nicotine and / or at least one aroma, and to an electronic cigarette containing this composition.BACKGROUND OF THE INVENTION[0002]The electronic cigarette market is currently expanding greatly, because it allows the consumer to preserve the ritual associated with the use of the cigarette without suffering the detrimental effects of the harmful substances that it contains.[0003]The electronic cigarette or e-cigarette works with electricity without combustion. It produces a mist of fine particles, commonly referred to as vapor or artificial smoke, which visually resembles the smoke produced by the combustion of tobacco. This vapor can be flavored (tobacco, mint, fruit, chocolate aroma, etc.) and it may or may not contain nicotine. In correctly manu...
