An In-Sight on Vape Juice

Vape Juice is the liquid used in the vaping device to produce vapors. It is also referred to as e-juice or e-liquid. As the E-Cigarettes industry sees exponential growth year after year, consumers are spoilt for choice, with countless vape juice flavors to pick from. The nicotine level can also be altered, including zero nicotine levels for those who do not prefer the same. The history of e-juice can be traced down to the first smokeless cigarette invented by Herbert A. Gilbert, an innovator from the US in 1963.

Although his invention was commercially unsuccessful mainly because it was nicotine-free, tobacco companies took up the basic idea. Nicotine-based aerosol-generating devices started being manufactured by tobacco companies, which used a rudimentary form of e-liquid. Finally, the modern e-juice with variable flavors came into the picture with the first commercially viable e-cigarette invented by Chinese pharmacist Hon Lik in 2003.

Understanding the Composition of E-Juice

Usually, the base substance of vaporizer juice is propylene glycol (PG) with the required edible flavor and water. Alternately, Vegetable Glycerin (VG) could also be used as the base material instead of PG. Nicotine is also present in the e-liquid unless it happens to be a nicotine-free version. All well-known e-juice brands strictly use permitted food-grade flavors only, similar to the ones used in processed foods like jam or cereal.

It is therefore recommended to buy e-juice manufactured by reliable brands only. Trusted online vape stores like provide a good assortment of high-quality e-juice brands and flavors to take a pick. Percentage-wise, the base material along with water constitutes 90% of the e-liquid. The reason for using PG or VG is that both of these are food-grade, and ideal substances for uniformly dispersing the flavoring agent added (about 10%) in the entire solution.

Vape Juice: PG versus VG

Both Vegetable Glycerin (VG) and PG (Propylene Glycol) are safe and efficient base constituents for e-juice manufacture. But there are characteristic differences between PG-based E-liquids and VG-based E-Liquids. Understanding these differences can help you make a better choice as per your preferences, thus enhancing your vaping experience. Here are the 4 key differentiators:-

  • Consistency- PG-based e-juice is always thinner in consistency as compared with the thicker VG-based variant.
  • Residue- Having lesser viscosity, the residue left by PG juice on the drip-tip or vape tube is much lesser than that of VG juice.
  • Flavor- Those who prefer sweeter flavor should opt for VG-base owing to its inherent sweetish nature. PG does not add on to the flavor in any major way.
  • The throat hit of PG-based e-liquid is greater than that of the VG-based one.
  • Vapor Cloud is larger and so is the vapor cloud density, in case of VG e-juice.
  • Vapor Temperature is higher for e-liquids with PG-base.
  • An extremely important point of difference is that PG could trigger allergies in a small percentage of users. Symptoms include a dry and sore mouth. If you happen to be allergic, you should always opt for VG-based vaping juice which is non-allergenic.

On the whole, PG e-juice is marginally more popular than VG, but it is a subjective choice for most vape users. As vaping enthusiasts become more discerning and particular about their needs, the trend of combining PG and VG e-liquids has also become common now. This combination is usually done with either 80:20 PG-VG ratio or 80:20 VG-PG ratio.

Since VG and PG are dense liquids, these tend to settle at the bottom of the e-juice bottle. So the bottle needs to be shaken well before use. After shaking, the next step is uncapping and pouring into the atomizer, which needs to be done very carefully. Always refer to the refilling instructions and follow them religiously.

Nicotine Levels in Vaping Juice

There are three broad variants of nicotine levels in e-juice.

  • For those who need a strong nicotine dose, the nicotine content would approximately be 24mg and above.
  • Mid-range nicotine users can choose anywhere between 10mg to 17mg, based on their preference.
  • Lowest nicotine concentration varies from 3mg to 6mg, preferred by new users.

With the popularity of vaping is increasing consistently, there is a sizeable demand for nicotine-free e-liquids as well.
