Vegetable Glycerin is a carrier fluid used to hold the flavour in E-Liquid. It is odorless and commonly used in the food and cosmetic industry. Vegetable Glycerin is an organic compound produced from vegetable oil. VG allows E-Liquid to be vaporised by the atomiser, producing the vapor that is inhaled into the lungs.
VG is classed as a carbohydrate for food purposes. VG is hypoallergenic, and is found in hypoallergenic soaps, cosmetics and other products. VG naturally has a sweet taste, and though it is a carbohydrate, it does not have a drastic effect on blood sugar and can be safely used by those who require insulin.
