Vaping has gained significant popularity in recent years as
an alternative to traditional smoking. Central to the vaping experience is the
e-liquid, a fluid that is heated and transformed into vapour for inhalation.
With a wide range of flavours, nicotine strengths, and base ingredients,
e-liquids offer a diverse and customizable vaping experience. You might have
heard names of e-liquid like 50/50 vape juice, 70/30 e-liquids, but what do these titles imply? And most
importantly what are they made of?
Ingredients of E-Liquid
Base Ingredients:
E-liquids typically consist of a base that forms the
foundation of the vaping experience. The two main types of base ingredients are
propylene glycol (PG) and vegetable glycerin (VG). Here's a breakdown of their
characteristics:
Propylene Glycol (PG):
PG is a colourless and odorless liquid with a thinner
consistency. It provides a stronger throat hit and carries flavours
exceptionally well. E-liquids high in PG tend to produce less vapour but offer
a more intense flavour experience.
Vegetable Glycerin (VG):
VG is a thicker and sweeter liquid that creates dense vapour
clouds. It provides a smoother throat hit and is ideal for those who prefer a
milder sensation. E-liquids high in VG may have a slightly muted flavour compared
to PG-based options.
Nicotine Strength:
E-liquids come in various nicotine strengths, allowing
vapers to tailor their vaping experience according to their preferences. Here
are the most common nicotine levels:
a. High Nicotine:
Suitable for heavy smokers transitioning to vaping, high nicotine e-liquids
typically range from 12mg to 24mg per milliliter (ml).
b. Medium Nicotine:
Moderate smokers often opt for e-liquids with nicotine levels between 6mg and
12mg/ml.
c. Low Nicotine:
Vapers who have significantly reduced their nicotine consumption may choose
e-liquids with nicotine levels around 3mg/ml.
d. Nicotine-Free:
For those who enjoy vaping without nicotine, there are a plethora of
nicotine-free e-liquids available, providing a purely flavourful experience.
The Two primary components of e-liquids are propylene glycol
(PG) and vegetable glycerin (VG). In this comprehensive guide, we will delve
into the properties, uses, and differences between PG and VG, helping you make
informed decisions about your vaping experience.
Properties of PG
Propylene glycol is a synthetic organic compound commonly
used as a food additive, solvent, and humectant. In e-liquids, PG serves
several important purposes:
a. Throat Hit: PG
provides a throat hit, the sensation similar to smoking traditional cigarettes.
If you prefer a stronger throat hit, e-liquids with a higher PG ratio are
suitable.
b. Flavour Intensity:
PG acts as a carrier for flavours, enhancing the taste and aroma of e-liquids.
It effectively transports the flavours and ensures a more pronounced taste.
c. Thin Consistency:
PG is less viscous than VG, resulting in a thinner consistency of e-liquids.
This property is particularly advantageous for devices with smaller wick
openings, such as pod systems and certain atomizers.
d. Low Vapour:
Production: Due to its thin consistency, PG produces less vapour compared to
VG. If discreet vaping is your preference, or you simply enjoy a subtler vapour
output, e-liquids with a higher PG content would be suitable.
Properties of VG
Vegetable glycerin, often derived from plant oils such as
soy, coconut, or palm, is a natural and organic compound widely used in various
industries. In e-liquids, VG offers the following characteristics:
a. Thick Vapour
Production: VG is significantly more viscous than PG, leading to denser
vapour clouds. If you enjoy large and billowy vapour production, e-liquids with
a higher VG ratio are preferable.
b. Smoothness: VG
contributes to a smoother vaping experience, often referred to as a
"creamy" or "smooth" sensation. It provides a milder throat
hit, making it ideal for vapers who find PG too harsh.
c. Sweetness: VG
has a slightly sweet taste, which can impact the overall flavour profile of an
e-liquid. Some users find that higher VG content can slightly mute certain
flavours, particularly delicate ones.
d. E-Liquid
Consistency: Due to its higher viscosity, VG adds thickness to e-liquids.
This property is beneficial for devices with larger wick openings, as it helps
prevent dry hits and promotes better saturation of the wicking material.
PG/VG Ratios:
E-liquids are typically labeled with a PG/VG ratio,
indicating the relative amounts of propylene glycol and vegetable glycerin in
the formulation. Common ratios include 50/50, 70/30, and 30/70, although there
are many variations available.
Finding the Right Ratio:
The ideal PG/VG ratio depends on personal preferences and
vaping goals. Here are some common ratios and their characteristics:
a. 50/50 (Equal
Ratio): A balanced blend of PG and VG that provides a moderate throat hit,
good vapour production, and well-defined flavours. This ratio is suitable for
beginners or those who desire a well-rounded vaping experience.
b. High PG (e.g.,
70/30 or 60/40): These ratios offer a stronger throat hit, intense flavour
profiles, and lower vapour production. High PG e-liquids are often favored by
those who are transitioning from smoking or enjoy a more pronounced throat hit.
c. High VG (e.g.,
70/30 or 80/20): These ratios provide smoother throat hits, slightly muted
flavours, and dense vapour clouds. High VG e-liquids are popular among cloud
chasers or vapers who prioritize vapour production over throat hit.
The PG/VG ratio in your e-liquid significantly impacts your
vaping experience. By understanding the characteristics of PG and VG, you can
select the ratio that aligns with your preferences. Whether you prioritize
throat hit, flavour intensity, or vapour production, experimenting with different
PG/VG ratios will allow you to fine-tune your vaping experience and find the
perfect balance that enhances your enjoyment. Remember, everyone's preferences
are unique, so don't hesitate to explore different ratios to find the one that
suits you best.
