Pure VG or PG – premium 60ml bottle (Vegetable glycerin or Propylene glycol)

Vegetable glycerine

Liquid designed for modern atomisers is mostly vegetable glycerine, or VG – this can be up to
80% by volume. If you want to know how it is that e-cigs have gone from producing a little wisp
of thin vapour to belching out huge white plumes, this is why.

Glycerine is a natural substance that can be processed from most kinds of fat. The glycerine
used in e-liquid comes from vegetable oils, which is why it’s called VG, but it doesn’t really
make a lot of difference. One important point is that although it’s processed from oils it isn’t an
oil. In fact it’s an alcohol, which makes it safe to inhale.
VG is a non-toxic colourless liquid with no smell, but a sweet taste. It’s very thick and viscous,
which means high-VG liquids don’t work well in older atomisers and small clearomisers – it’s
too thick to wick well. Some liquids use aqueous glycerine to solve this, basically just VG with
some water added.

Lots of common products contain VG. It’s used in the food industry as a sweetener, and also
added to some foods to keep them moist. Many medicines contain it too. Scientists have
studied it for years, and it’s never been linked to any health problems.
Liquids with a lot of VG produce lots of dense vapour, but not a lot of throat hit.

Propylene glycol
Most of what isn’t VG in your liquid is probably propylene glycol, or PG. Some liquids contain
more PG than VG; these work better in clearomisers and older atomisers, because they’re less
viscous.

PG is an alcohol, like VG, and it’s also nearly odourless. It has a faint sweet taste, although not
enough for it to be used as a sweetener; it does get added to foods, medicines and other
products to keep them moist, though.

One other use for PG is in antifreeze, and it’s because of this that some people like to claim e-
juice contains antifreeze. In fact this is totally dishonest. PG is only one ingredient in antifreeze,
and it’s actually there because it’s non-toxic; PG-based antifreeze is less harmful to children and
pets. It’s worth pointing out that water is also an ingredient in antifreeze; just because
something is used in a product that has a reputation for being poisonous, that doesn’t say
anything about how harmful that substance is.

It’s true that there have been some minor health issues linked to PG. It’s been studied since the
1940s and is classed as generally safe; swallowing or inhaling it won’t do you any harm. A small
percentage of people are sensitive to it, though, so if liquid with a high PG content makes you
feel unwell, switch to one with more VG.

PG produces less visible vapour than VG, so it’s unpopular with cloud chasers but liked by
people who want to vape discreetly. It also carries flavours better and gives more throat hit.
