What are E-Liquids and differences between them?
If you are new to the world of e-cigarettes, it is understandable if you are feeling overwhelmed by all the new terms and jargon you have to deal with. However, when you get the hang of it, it is not such a complicated world after all. One of the terms that is bandied about in the world of e-cigarettes is e-liquid.
E-liquid is the solution which fuels your electronic cigarette. It is basically a nicotine based solution with flavor enhancements which is used to create the vapor that you inhale and mimics the sensation of drawing on an actual tobacco based cigarette. However, it is not all the e-liquids which contain nicotine.
What are the Ingredients Used to Formulate e-Liquids?
An e-liquid is made of a base ingredient and often some flavor. There are two compounds used to form the e-liquid's base. The two are Propylene Glycol (PG) and Vegatable Glycerin (VG). To create unique flavors, manufacturers of e-cigarettes also add flavors such as menthol, vanilla or apple to ensure the electronic cigarettes fit the preferences of their customers.
Different e-liquids may come with either PG or VG as the base and the proportion of either is all upon the manufacturer to decide. You may find one brand of e-cig with a PG/VG proportion of 70/30 while another has them in a ration of 50/50. Many e-cigarette users experiment with different varieties before settling on one as their ideal choice.
Let us take a look at what each of these base ingredients represent:
What is PG (Propylene Glycol)?
Propylene Glycol is the most commonly used base ingredient for electronic cigarettes. Indeed, PG has a wide range of uses in the foods and pharmaceutical industry. It is an FDA approved compound that is also considered safe for human consumption around the world. It is virtually tasteless and offers an uncanny, throaty hit, similar to what you get when you draw on an actual tobacco-based cigarette.
As PG is much thinner than VG, it vaporizes more easily and is absorbed well by the polyfill compound in your e-cigs cartomizer. The only disadvantage compared to VG is that PG does not produce as much vapor. It has also been established that a very small percentage of e-cig users have a mild allergic reaction to PG. For such, it is advisable to stick to VG based e-cigs as a matter of course.
What is VG (Vegetable Glycerin)?
Vegetable Glycerin is a thick, sweet and distinctively flavored vegetable based liquid. Just as the case with PG, VG is an FDA approved substance that is widely considered safe. Unlike PG though, VG is not a product of a chemical procedure in a lab: it is wholly extracted from vegetable or plant oils.
