What is Propylene Gylcol?
If you’re familiar with vaping, you’ve probably heard the term ‘PG’ mentioned to describe e-liquid. This abbreviation stands for Propylene Glycol and refers to one of the main substances which forms the base of all e-liquids - the other being Vegetable Glycerin. Both of these liquids are considered extremely safe and non-toxic and by altering the volume of each substance it is possible to achieve different thicknesses, and as such, different vaping experiences.
‘Classic’ e-liquids contain a higher level of PG than VG which helps to create the thin consistency and satisfying ‘throat hit’ often likened to the sensation of smoking. This makes classic liquids the preferred choice for those looking to quit tobacco using a low-wattage Pen-Style Kit.
‘Sub ohm’ liquids, however, have a higher percentage of VG than PG and because VG is a thickening agent, these e-liquids are more suited for high-wattage sub ohm devices which are designed to produce a lot of vapour and very intense flavour.
