Propylene Glycol (PG) based E-liquids versus Vegetable Glycerin (VG) based E-Liquids, Which is Better?
E-liquid (a.k.a E-juice) is primarily made out of four key ingredients: a Propylene Glycol and/or Vegetable Glycerin (VG) base, flavourings, water & sometimes nicotine (when permitted by law). The base, also known as the carrier, contains the flavour and the nicotine, and suspends them to allow the e-cigarette emit vapour clouds which resemble smoke. Since, Propylene glycols & vegetable glycerin are non toxic organic compounds, it’s considered safe to consume them. They are also popularly used in the form of food additives in many commercially sold goods.
As Propylene Glycol is more popular in comparison to Vegetable glycerin, we will first elaborate upon PG-based e-liquid. Basically, propylene glycol possesses a thin consistency and such e-liquids flow more easily as compared to the VG form. Besides, it is also easier for the polyfill fabric within the cartomizer to absorb it. Because the juice does not have a higher density as compared to the relatively thicker vegetable glycerin liquid, it prevents the slime and gunk from accumulating faster when you heat the e-cigarette. The flavour of the e-liquid remains unchanged as Propylene glycol is basically tasteless and odorless. It is a strong humectant and performs effectively when used in electronic cigarettes as it produces a greater throat hit akin to tobacco cigarettes.
Vegetable glycerin is thicker than propylene glycol. Its sweet taste adds sweetness to the e-liquid and this makes it tough to identify the flavours. Some users have stated that phlegm starts building in the throat when they began to use vegetable glycerin-based juices. Although the VG is not able to give you a great throat hit, still its higher consistency helps the Vegetable Glycerin e-liquids to emit more vapours, this is something that die-hard vapers are more interested in compared to people who are using electronic cigarettes as an alternative to conventional cigarettes.
The vaping community is almost evenly at odds while choosing the e-liquid of their choice. One segment loves the smoking like throat hit which propylene glycol juices are known for, while the other segment enjoys the thick smoke rings and the sweet tinge of vegetable glycerin.
It is tough to compare both and selecting any one out of them is a matter of personal choice. If you wish for an experience which closely resembles smoking a traditional cigarettes, then I would recommend using our e-cigs which contain the more popular Propylene Glycol (PG) e-liquid.
