E liquids – PG and VG – What you Need to Know

In order to prevent smokers from the harms of tobacco and provide them with a similar experience of smoking, e-cigarettes have been introduced to the market. It consists of e liquids which acts as a fuel to light up an e-cigarette. It is this liquid which provides a nicotine solution and flavour to every electronic cigarette.

Talking of experience, every cigarette smoker differs from one another and so does their taste. This taste and flavour are produced by the use of a couple of chemicals which act as base ingredients for all e-liquids. These ingredients are Propylene Glycol (PG) and Vegetable Glycerine (VG). These two ingredients are mixed in various proportions along with flavours such as vanilla or apple in order to give smokers the ultimate vaping experience.

Before going into more depth about perfect ratios of VG and PG, it is worthwhile to have a knowledge of these basic terms related to e liquids:-

  • Vaping:-

Invented by Hon Lik, a Chinese pharmacist, vaping is an art of smoking minus all the harmful effects of tobacco and nicotine. People inhale and exhale water vapours produced by e-cigarettes which contain flavours of one’s desired taste. These flavours might include vanilla, chocolate, pineapple and others.

  • Throat hit:-

Considered as a major component of overall smoking experience, throat hit is defined as a feeling a person gets at the back of his throat after inhaling vaporised liquid from an e-cigarette. Higher nicotine level accounts for stronger throat hits as compared to lower nicotine levels. It is this strength of a hit which helps people choose various VG/PG ratios.

  • Vegetable Glycerine or VG:-

Vegetable Glycerine is comparatively a thicker, heavier and sweet tasting liquid. It is extracted by a process known as Hydrolysis and constitutes of:-

  1. Palm oil
  2. Coconut oil
  3. Soy

People who are slightly allergenic to Propylene Glycol mainly use VG as their e liquids constituent. It is known to provide a very smooth throat hit to e-smokers and provides a much thicker vapour as compared to traditional smoking.

  • Propylene Glycol or PG:-

This chemical is known to be a better half of VG in e liquids. It is sweeter and thinner as compared to Vegetable Glycerine. Propylene Glycol is particularly popular with smokers as it is known to provide a stronger throat hit as compared to VG.

Why is nicotine needed in e-cigarettes?

Nicotine is a potent parasympathomimetic stimulant. In other words it causes addiction. It constitutes approximately 0.6-3.0% of the dry weight of tobacco. Vapers use nicotine in their vaping e liquids as per their need to define a particular dose of addiction at which they are comfortable. Use of nicotine along with the base ingredients mixed in right proportions make up a prefect liquid to be used for vaping purposes. Since, addiction is repetitive, so is nicotine use in e-liquids.

Densities of Nicotine available in e liquids

Nicotine is known to give addictive feeling that keeps people lured to cigarettes whether electric or traditional. Companies add nicotine to e-cigarettes in certain densities. On an average, five main nicotine densities are provided by e-cigarette companies:-

  • No nicotine – 0 mg Nicotine.
  • Extra Light variant which contains 6 mg Nicotine.
  • Light variant containing 12 mg Nicotine.
  • Regular variant comprising 128 mg Nicotine.
  • Strong variant which constitutes 24 mg Nicotine.

Now, having received some knowledge about PG ,VG and strengths of nicotine constituency, it is time to know the various combinations and ratios in which they are mixed to produce a perfect vaping experience. Combinations can range from 100% Vegetable Glycerine to 100% Propylene Glycol. A closer look into each combination will help clear more doubts.

  1. People who love that strong hit might opt for a 100% Propylene Glycol e liquids It is also known to deliver the best feeling of most flavours. It is known to provide very less quantity of vapours owing to its thin nature and absence of VG.
  1. 20% VG/80% PG is another combination which is considered to be relatively less popular compared to others. Fine tuning this ratio to 30% VG/70% VG has made it quite acceptable in recent times. It produces slightly lesser throat hit but emits lot of vapour as by product.
  1. An equal ratio of 50% VG/ 50% PG is considered to be a good starting point for entry level smokers. It is popularly named as experimentation ratio owing to its equal distribution of the two liquids.
  1. Considered to be the best vaping ratio, 70% VG/ 30% PG is greatly accepted by everybody. This particular blend makes it way to most commercial e liquids manufacturing plants. It is known to produce large volumes of vapours as well as causing a smooth throat hit. Many vapers consider it to be the best of both worlds.
  1. Choice of 100% VG occurs due to two reasons – due to an allergy to Propylene Glycol or competitive cloud chasing. This is particularly sweet in flavour and more easily usable by mass smokers. It offers a minimal throat hit but creation of large amount of vapours makes up for missed out throat hits.

So, it is quite important to decide on the right composition and ratio of Propylene Glycol and Vegetable Glycerine. Different smokers have different choice of ratios. While some like it strong, others go for a relatively moderate throat hit. Moreover, Nicotine constituency is another important factor to be considered while choosing your desired e liquids. Correct choice of strength is vital as consuming more than required can lead to addiction.

If you are interested in trying out sample ratios of PG/VG, contact a reliable dealer today and decide which composition suits you the most. This is of grave importance especially to those who are trying to substitute traditional smoking with a rather less harmful option. Irregular doses of e liquids can be detrimental to their purpose to quit smoking.
