Why PG and VG in liquid e juice
2
VG (Vegetable Glycerin) vs. PG (Propylene Glycol)
When it comes to e-juice, two terms constantly
crop up VG and PG. Typical e-juice or e-liquid
contains four ingredients. These ingredients
are- Propylene Glycol (PG) or Vegetable Glycerin
(VG), water, flavoring, and nicotine The
presentation will give a brief understanding
about both.
3
What are PG and VG?
PG and VG are the odorless liquids that are
combined with flavor and nicotine to
create?e-juice. Both PG and VG technically
belong to the?alcohol?chemical class (despite the
name, they are not intoxicating). They are deemed
sugar alcohols and are included in many
consumable products. They produce vapor when
heated, which allow them to be inhaled. PG and
VG are not oils, and cant cause any of the
medical issues like?lipoid pneumonia? that
inhaling actual oils can. The two fluids have a
different consistency to each other and a
slightly different taste. They have distinct
mouth and throat sensations when vaped. Most
modern e-liquid uses a combination of the two
fluids, though the ratio can vary dramatically.

Propylene Glycol (PG) E-juice
It is less viscous than Vegetable Glycerin and
easier to handle when (re)filling your atomizer,
cartomizer, or clearomizer. Propylene Glycol
(PG) has low density which means you will get
less gunk when compared to Vegetable Glycerin
(VG). It is absorbed much faster by wick
material and polyfill fabric, which means that
you can start vaping faster. Since Propylene
Glycol is tasteless and odorless there is little
or no flavor distortion.

Vegetable Glycerin (VG) E-juice
Vegetable Glycerin (VG) is less popular when
compared to Propylene Glycol (PG) base. It has
much higher viscosity, which makes it a perfect
base for vapers who love a thicker and higher
density vapor cloud. It is easier on your throat
which means it delivers less throat hit.  higher
viscosity of Vegetable Glycerin (VG) typically
requires more power and longer time to achieve
optimal vaping temperature. Unlike PG base,
Vegetable Glycerin contains preexisting flavor
and sweetness. This means that in many cases the
added flavoring will be diluted and final product
(e-liquid) will be sweeter.

How to choose between PG and VG E-liquid?
PG e-liquid tends to give you a better throat hit
and a lot more flavor. VG e-liquid on the other
hand, allows your atomizer to produce a lot more
vapor. VG e-liquid is a thicker and more sticky
fluid, and although most people do not show signs
of allergy with VG, there are minority groups who
complain about having phlegm buildup in their
throats. The more VG e-liquid you use, the less
of a throat hit youre going to get thats the
general idea. The vaping community is evenly
divided when it comes to e-liquid
preference. Some enjoy the intense throat hits
more than flavor and vapor, others enjoy the
sweet, thick plumes of vapor.
7
Can You mix PG and VG?
60 / 40 mix of VG and PG in your e-liquid can
produce great vapor and more flavor. If you
like, you can tend to use mix of both PG and VG
in particular ratios, such as 70 VG / 30 PG. This
is the optimum ratio for most each uses as it
provides a nice throw hit, good flavor as well as
tons of vapor production. Vegetable Glycerin
(VG) more vapor, less throat hit. VG e-liquid is
thick and a little sweet. It produces luscious
clouds of vapor.  VG e-liquid also imparts a
sweeter taste to your liquid. (VG eliquid is
available in Tobacco and Menthol flavors). Propyl
ene Glycol (PG) better throat hit and flavor. PG
e-liquid is thinner and produces  more of a
throat hit than VG e-liquid does, which
simulates the feel of smoking better.  PG
e-liquid also has a higher rate of sensitivity
for some people, meaning that some people just
can't use PG in their vape. Usually side effects
are mild allergy symptoms.

What should I be aware of when vaping PG?
Some people find a high level of PG irritating to
the throat. If you find yourself coming out in
a rash or suffering other unpleasant reactions
after using PG-based e-fluid, you may have a more
common mild sensitivity to PG, and should look at
using high-VG juice instead. The most common
side effects of using e-liquid containing
propylene glycol are symptoms of dehydration,
like dry mouth, sore throat, and increased
thirst. It is advised to drink more water and
liquids than usual for the first few weeks of
using your e-cigarette. If hydrated properly,
these symptoms usually last anywhere from a few
days to a week as the body gets used to the
propylene glycol.
9
What should I be aware of when using VG?
The increased thickness of VG means it can reduce
the life of?atomizers?quicker than PG-based
juice. High VG liquids clog up coils more
rapidly, and will not work well, if at all, in
certain tanks. Older products are especially
susceptible, particularly models that use smaller
coils such as clearomizers. As with PG, the
most common?side effects of vaping?high VG
e-liquid are those of dehydration dry mouth,
sore throat, and increased thirst. Again, be
sure to drink plenty of water and take a break
from vaping if necessary.

Conclusion
The basics of PG and VG are quite easy to grasp.
They both work in different ways, and each has
advantages and disadvantages. It is better to
start with a 50-50 PG to VG ratio then try out
various combinations and see which you prefer.
Many vapers like to use different levels of PG
and VG at different times, and with various
devices and flavors. Tobaccos, fruits and
beverage flavors often go well with PG.
Similarly, flavors based on cream, custard and
yogurt tend to work well with high VG. There are
no fixed rules, just follow what your taste buds
tell you!
