E-Juice – What is it in Vaping?

Definition

E-Juice—also called E-Liquid or VapeJuice“>vape juice—is the flavoured fluid that fuels every E-Cigarette, eGo Style pen, E-Shisha hookah pen, or any other vaping device. It is a carefully balanced blend of food-grade ingredients designed to be heated into an inhalable aerosol (vapour). Its primary purpose is to deliver nicotine (or be nicotine-free) while satisfying flavour cravings, replacing the smoke of combustible cigarettes with a smoother, customisable experience.

Technical Details

Composition & Chemistry

E-Juice typically contains four core components:

  • Propylene Glycol (PG) – a thin, flavour-carrying base that provides a Hit“>throat hit similar to tobacco smoke.
  • Vegetable Glycerin (VG) – a thicker, slightly sweet base that creates dense vapour clouds.
  • Nicotine – pharmaceutical-grade nicotine salts or freebase nicotine, measured in mg/mL (0 mg to 50 mg).
  • Food-grade flavourings – natural or artificial concentrates ranging from fruits and desserts to tobacco or menthol.

Specifications & Variations

Common PG/VG ratios include 50/50 for mouth-to-lung devices, 70/30 for sub-ohm tanks, and max-VG (80–90 %) for rebuildables. Nicotine strengths span 0 mg, 3 mg, 6 mg, 12 mg, 18 mg, and higher for nic-salt pods. Short-fill bottles (60 mL with 50 mL juice) allow users to add nicotine shots, adhering to Australia’s import regulations.

Usage & Tips

  • Priming coils:Drip 3–5 drops directly onto a fresh coil and fill the tank; wait 5–10 minutes to prevent dry hits.
  • Storage: Keep bottles sealed, away from heat and sunlight to preserve flavour and nicotine potency.
  • Common issues:Leaking often stems from over-tightening or worn O-rings; gunked coils indicate high-sweetener juice—switch to clearer flavours or lower wattage.
  • Safety: Always use child-resistant caps, store out of reach of kids and pets, and never ingest E-Juice. When using an Battery“>External Batterymod, ensure batteries are wrapped and paired correctly.

History & Context

E-Juice emerged in 2003 alongside the first commercial E-Cigarette in China. Early formulations were simple PG/VG blends with tobacco flavours. Over two decades, the market evolved to nic-salts, complex dessert profiles, and nicotine-free options. In Australia, TGA regulations and import limits continue to shape how vapers source and mix their favourite E-Liquids today.
