With an endless variety of e-liquids available to vapers, finding what e-liquid is best for you and your vape may seem overwhelming. Let’s start with the basics. All e-liquid is made up of either a vegetable glycerin base or a propylene glycol base. Varied nicotine levels are added, as well as flavors. A propylene glycol based e-liquid is thinner than vegetable glycerin based. This means that it creates thinner clouds than vegetable based e-liquids, but because it is thinner does not cause as much build up in your vape. Propylene glycol based e-liquids also tend to have a stronger flavor. The vegetable based e-liquids, due to their thickness need more cleanings. Of course, many e-liquids are made of a combination of both propylene glycol and vegetable glycerin. The ratio determines thickness and flavor.
