Description
[0001] This application claims the priority of the China Patent
Application No. 201310625207.3, filed with the Patent Office of
China on Nov. 28, 2013, titled "A SOLVENT FOR ELECTRONIC CIGARETTE
LIQUID AND AN ELECTRONIC CIGARETTE LIQUID", the contents of which
are incorporated herein by reference in its entirety.
FIELD OF THE INVENTION
[0002] The present invention relates to the technical field of
electronic cigarette, and particularly to a solvent for electronic
cigarette liquid and an electronic cigarette liquid.
BACKGROUND OF THE INVENTION
[0003] An electronic cigarette liquid is an essence extracted from
a plant, to which an edible flavor is added. It has a strong
antioxidant activity, and is free of harmful substances such as
carbon monoxide and tar. The electronic cigarette liquid mainly
comprises a solvent, a tobacco flavor and/or fragrance, and a
tobacco extract. The traditional tobacco smoke contains toxic
substances such as carbon monoxide, nitrous oxide, formaldehyde,
ethanol, methane, toluene, hydrogen cyanide, lead, aluminum, zinc,
magnesium, etc., and carcinogenic substances such as benzopyrene,
chloroethylene, nitrosamine, polycyclic aromatic hydrocarbons,
nitrosotoluene, cadmium, nickle, polonium 210, etc. However, the
electronic cigarette liquid is heated by electric heating, in order
to atomize a solution comprising a flavor into atomized particles.
Smoke can be generated upon suction, which provides a feeling of
smoking. However, it neither burns nor generates new harmful
substances. Therefore, the electronic cigarette liquid is healthier
than the traditional cigarettes. Using of the electronic cigarette
liquid instead of the traditional cigarette can reduce harm and
avoid pollution of second-hand smoking, and represents a great
progress in the development of tobacco.
[0004] The electronic cigarette liquid is a liquid utilized in the
electronic cigarette cartridge. An electronic cigarette comprises a
battery, an atomizer and a cartridge, and works as follows: the
cartridge directs the liquid into the atomizer--the atomizer is
energized by the battery--the atomizer is heated to evaporate the
cigarette liquid into atomized particles. The electronic cigarette
liquid has strict requirements on its components: the solvent must
be of food or pharmaceutical grade; the flavor for the electronic
cigarette must be of high quality. At present, propylene glycol and
glycerol are mainly used as the solvent for the electronic
cigarette liquid. However, the smoke formed by such electronic
cigarette liquid is greasy. In addition, glycerol is characterized
by water absorption, readily renders a dry throat of the smoker,
and thus results in a poor experience of the smoker.
SUMMARY OF THE INVENTION
[0005] The object of the present invention is to provide a solvent
for electronic cigarette liquid and an electronic cigarette liquid.
The smoke formed by the electronic cigarette liquid which is
prepared with the solvent for electronic cigarette liquid provided
by the present invention is not greasy, neither too dry nor too
wet.
[0006] The present invention provides a solvent for electronic
cigarette liquid, comprising sorbitol.
[0007] Preferably, the mass concentration of sorbitol is 60 wt
%.about.70 wt %.
[0008] Preferably, the solvent for electronic cigarette liquid
further comprises one or more of propylene glycol, glycerol, and
mannitol.
[0009] Preferably, the solvent for electronic cigarette liquid
comprises the following components:
[0010] 35 wt %.about.63 wt % of sorbitol;
[0011] 10 wt %.about.50 wt % of propylene glycol;
[0012] 15 wt %.about.27 wt % of water.
[0013] Preferably, the solvent for electronic cigarette liquid
comprises the following components:
[0014] 21 wt %.about.35 wt % of sorbitol;
[0015] 50 wt %.about.70 wt % of glycerol;
[0016] 9 wt %.about.15 wt % of water.
[0017] Preferably, the solvent for electronic cigarette liquid
comprises the following components:
[0018] 10.5 wt %.about.35 wt % of sorbitol;
[0019] 10 wt %.about.50 wt % of propylene glycol;
[0020] 25 wt %.about.40 wt % of glycerol;
[0021] 4.5 wt %.about.15 wt % of water.
[0022] Preferably, the solvent for electronic cigarette liquid
comprises the following components:
[0023] 21 wt %.about.63 wt % of sorbitol;
[0024] 10 wt %.about.70 wt % of mannitol;
[0025] 9 wt %.about.27 wt % of water.
[0026] The solvent for electronic cigarette liquid comprises the
following components:
[0027] 7 wt %.about.28 wt % of sorbitol;
[0028] 10 wt %.about.30 wt % of propylene glycol;
[0029] 5 wt %.about.30 wt % of glycerol;
[0030] 15 wt %.about.30 wt % of mannitol;

[0036] The present invention provides a solvent for electronic
cigarette liquid, comprising sorbitol. In the present invention,
sorbitol is used as the solvent for electronic cigarette liquid.
The electronic cigarette liquid which is prepared with the solvent
for electronic cigarette liquid provided by the present invention
is not greasy and free of miscellaneous taste, and therefore

[0137] As can be seen from Table 1, the electronic cigarette liquid
which is prepared with the solvent for electronic cigarette liquid
provided by the present invention can generate a relatively greater
amount of smoke which is slightly sweet, and provide a thick, full,
smooth mouthfeel without any miscellaneous taste, and therefore
improves the experience of the smoker.
[0138] As is known from the above examples, the solvent for
electronic cigarette liquid provided by the present invention
comprises sorbitol. In the present invention, sorbitol is used as
the solvent for electronic cigarette liquid. The electronic
cigarette liquid which is prepared with the solvent for electronic
cigarette liquid provided by the present invention is not greasy
and free of miscellaneous taste, and therefore provides relatively
higher comfort level during smoking. Further, the electronic
cigarette liquid provided by the present invention may further
comprise one or more of propylene glycol, glycerol, and mannitol.
Due to the effects of propylene glycol, glycerol, and mannitol, the
sorbitol makes the electronic cigarette liquid which is prepared
with the solvent for electronic cigarette liquid provided by the
present invention generate a relatively greater amount of smoke,
improve the experience of the smoker, and provide a thick and full
experience, a smooth mouthfeel without any miscellaneous taste, and
a relatively higher comfort level during smoking. Furthermore, all
the components in the solvent for electronic cigarette liquid
provided by the present invention are of food grade, and are
harmless to the body of the smoker.
[0139] Illustration of the above examples is only to help
understanding the process and the core concept of the present
invention. It is to be noted that, a person skilled in the art can
further make various improvements and modifications to the present
invention without departing from the principle of the present
invention, which also fall within the protection scopes of the
claims of the present invention. Many modifications of these
examples would be obvious to a person skilled in the art, and the
general principle defined herein can be achieved in other examples
without departing from the spirit or scope of the present
invention. Accordingly, the present invention will not be limited
to the examples described herein, but should comply with the
broadest scope which is consistent with the principle and novel
characteristics disclosed herein.
