PG (Monopropylene Glycol USP) and VG (Veg Glycerine EP) are used in e-cigarettes production by making up the 'e-juice' or 'e-liquid'. The nicotine and flavourings are also contained within these liquids. When the product is activated the liquid is heated by the battery which produces the vapour that is inhaled and exhaled.
The e-liquids are made up from nicotine, water and flavouring, and will either contain PG (Monopropylene Glycol USP) or VG (Veg Glycerine EP). It is possible to mix both PG and VG together. A careful balance combining these ingredients will help to create the best smoke. It is with these varying levels of ingredients that can set your favourite brand apart from others available in the market.
PG (Monopropylene Glycol USP): is an organic compound which comes from Propylene Oxide, and is almost odour-free. PG has a slight sweet taste, and no colour, with low viscosity. As a miscible chemical it has many common uses, such as being used as preservative E1520 within food production. It is also used in tobacco products, e-cigratte products, medications, and a broad range of solvents.
VG (Veg Glycerine EP): comes from plant oils such as coconut, palm and even soy. It is a produced naturally and is usually both colourless and odourless. This is a fairly viscous chemical, and has many uses within the cosmetics and food industries due to its sweet taste. It can be used to substitute sugar, but unlike sugar does not contribute to tooth decay, and as such is used in many household products such as toothpaste.
