VG (Vegetable Glycerine)

Vegetable Glycerine is a clear, sticky, viscous, odourless liquid with a sweet taste, which is widely used in pharmaceutical formulations. It is used in electronic cigarette liquids mainly to produce extra vapour. It is usually mixed with Propylene Glycol, as Vegetable Glycerine is a much thicker liquid and can cause wicking problems with some atomisers and cartridge / cartomiser designs.

There are some nicotine liquids available though that are Vegetable Glycerine based. These tend to use 10 to 15% deionised water to thin them slightly, as some people prefer Vegetable Glycerine liquids to Propylene Glycol ones, as they produce a smoother and slightly sweeter vapour.
