When you want to enjoy a good electronic cigarette, you need to have a good quality e-liquid. Well, smoking electronic cigarettes itself is cool, but what makes it enjoyable is the e-juice. This is because it is what gives flavour and taste to the electronic cigarette. It contains a number of ingredients, for example nicotine, flavourings and diluents. There are two types of diluents used in the making of eliquids: propylene glycol (PG) and vegetable glycerin (VG). These two substances are very different from each other but very important in the manufacture.
Understanding Propylene Glycol
PG is a slightly thick juice that has no colour, murkiness or definite taste at room temperature. It has the capacity to produce vapour after heating or shaking it slightly. In electronic cigarettes, it is used to deliver nicotine when you inhale the vapour. Many e-cig users love propylene glycol simply because it gives a strong throat hit when smoking. This is the reason why most electronic cigarettes contain more PG than VG. On the other hand, it is said that PG causes dry mouth, but this is not a common occurrence with all users.
When used in electronic cigarettes, VG produces more vapour and is known for its rich taste. When compared to propylene glycol, vegetable glycerin is not as thick and does not cause dry mouth, as is the case with Propylene glycol. However, some manufacturers of e-juices and electronic cigarettes prefer mixing the two in different proportions. This means that it is important for you to find out whether the e-liquid you are using is a mixture of the two or only contains one of these two diluents.
In conclusion, the two diluents above, propylene glycol and vegetable glycerin, are the most important ingredients in the manufacture. Therefore understanding what they are is important to any electronic cigarette user.
