This is a question we’ve all wondered about when it comes to the components of e-liquids. Vegetable glycerin, propylene glycol, flavorings, and, optionally, nicotine are all present in the basis of most e-liquids in various amounts. There may be minor variations, but this is not common. You’ll see the differences fast if you understand the fundamentals. Meanwhile, we’ll leave you with the composition of the atomizer you’re using.


Liquids designed for today’s atomizers are typically utilized with high-power electronic cigarettes and have resistances with wide drains. Vegetable glycerin (VG) makes up a large component of most liquids, accounting for up to 80% of the total volume. VG is the explanation for why e-cigarettes have gone from producing little vapor to producing massive clouds.

Glycerin may be made from most fats as a natural substance, and e-liquid glycerin is made from vegetable oils, that is why it’s called VG. It does not differ significantly from them. The key difference is that it is not oil at all, despite being processed from oils. It is alcohol that makes e-liquids safe to inhale.

VG is colorless, non-toxic, and fragrance-free, even though it has a subtle sweetness to it. Because it is so thick, liquids with a high VG concentration may not function well with older or smaller atomizers. Aqueous glycerine is used to dissolve it in some solutions.

VG is included in many of the items we use daily. It is used as a sweetener in the food sector. It’s in some meals to keep them from drying out and becoming hard. This component can also be found in medicines. It has never been linked to any health issues, according to scientists. E-liquids with higher VG provide denser vapor that doesn’t hit your throat.


Another vital component of E-liquids is propylene glycol (PG). Some liquids have a higher PG content than VG. It assists liquids function better in older atomizers or resistors with a lesser drain. It is because they are less dense and have a lower viscosity than other liquids.

PG, like VG, is alcohol-based and odorless. PG has a slightly sweet flavor. However, it should not be used as a sweetener in excess. This component is also found in foods, pharmaceuticals, and other products to maintain their moisture.

Antifreeze is another application for PG. Many individuals mistakenly believe that e-liquids include antifreeze, which is completely inaccurate. Because of its non-toxicity, PG is the only constituent in antifreeze. Antifreeze with a PG base is safer for children and pets. Furthermore, water is a component of antifreeze.

PG creates less vapor (or, perhaps, it would be more correct to say density) than VG. As a result, it’s not as popular with cloud chasers as it is with those searching for a more discreet vaping experience.


One of the benefits of vaping is the variety of flavors available to consumers. It’s because of the scents. Food flavors are added to liquids because they have almost no taste of their own.

If there are any health risks associated with vaping, they are often related to the fragrances. Some compounds are safe for eating, but not for inhale (such as diacetyl). However, the industry has done a better job of eliminating compounds that were formerly a source of concern.


Nicotine is used as a fundamental component in numerous liquids. It makes vaping a viable alternative to quitting smoking. The presence of nicotine in e-liquids allows your body to absorb nicotine without having to burn tobacco leaves. Nicotine also delivers a satisfying throat hit. However, those who require a better throat hit should seek out liquids with higher nicotine concentrations.

Nicotine is a relatively safe substance. It is cigarette smoke, not nicotine, that is hazardous. Nicotine can be poisonous in high doses, but vaping makes it nearly impossible to become intoxicated. You’ll feel sick, have a headache, and so on before you reach dangerous levels. Vapers (and smokers) are aware of how much nicotine their bodies require and do not exceed it.
