What Is In Your Vape Juice: Understanding The Ingredients

PG at a glance:

• PG is a clear, tasteless and colourless base material used in many common products including inhalers.
• PG is used in e-liquids as it is a very effective carrier for flavourings and nicotine.
• PG is thinner in consistency than VG and produces far less vapour.
• 50/50 vape liquids are made using a higher volume of PG, allowing them to accommodate higher nicotine strengths.

PG (Propylene Glycol) is a clear, colourless liquid that’s a core ingredient in nearly all e-liquids. It acts as a highly effective carrier for both flavourings and nicotine, helping to deliver consistent taste and performance.

Its thin consistency means it doesn’t contribute much to vapour production, which is why 50-50 e-liquids—with their higher PG content—tend to produce smaller clouds compared to high-VG alternatives.

Thanks to this thinner profile, 50-50 vape juices absorb quickly into your coil. This makes them ideal for beginner-friendly vape kits with higher resistance coils (1.0ohm or more) and smaller wicking ports, ensuring smooth and satisfying hits.

PG is also widely used in everyday food items like cake mixes, fizzy drinks, food colouring, popcorn, baked goods, and a variety of fast food products.

The other of the two main ingredients, vegetable glycerine, is a clear, slightly sweet tasting, colourless liquid. VG is perfect e-liquid for creating the bigger clouds that many vapers enjoy. This increased vapour production also allows for more flavour concentrate to be inhaled, leading to a bolder vaping experience. VG has a very thick consistency and is the primary component in high VG e-liquids, often with an 80-20 VG and PG ratio. These thicker liquid vapes are ideal for sub-ohm vape devices (coils below 1 ohm) but typically have lower nicotine strengths because VG isn't as efficient a carrier as PG.

Flavourings are what provide the near-limitless variety in e-liquid flavours, from classic menthol to complex fruit blends. These e-liquid flavourings are usually suspended in a PG base for optimal blending with VG to create the final e-liquid solution. At EDGE, all our flavourings undergo rigorous testing for safety and come from reputable suppliers, ensuring they are food-grade and specifically designed for use in e-liquids for your total satisfaction.

Nicotine is a key component for many vapers transitioning from tobacco. There are different types of e-liquid based on the nicotine used:

Freebase Nicotine: This was traditionally, the most common form of nicotine used in e-liquids. It's called "freebase" because the nicotine is in its purest form, suspended in a base like PG (most common due to its carrier properties) or VG. EDGE uses freebase nicotine suspended in PG at a specific concentration to create our various nicotine strengths.  

Nicotine Salt (or Nic Salt or Salt E-Liquid): Nicotine salt e-liquid is a more recent innovation. In its creation, the nicotine is combined with a salt acid. This results in a smooth vaping experience with a less harsh throat hit, even at higher nicotine strength options like 20mg. Nic salt is also absorbed into the bloodstream more efficiently, providing faster and longer-lasting satisfaction. EDGE LIQ nic salts utilize Nicotine Salicylate for an unmatched flavour and overall user experience. If you're looking for a smooth vaping experience with potentially higher nicotine, salt e-liquids are a great choice.
