What Is The Background on Vegetable Glycerin (VG)- Vape Juice E-liquid
Vegetable Glycerin is an all natural liquid generally extracted from plant oils, in particular, soy, coconut oil, and palm oil. It is typically clear with little hint of color, odorless, in some cases sweet, and relatively viscous. Like Propylene Glycol it is considered safe by he U.S. Food and Drug Administration. The main applications of Vegetable Glycerin are cosmetics products, food production, and e-juice.
Vegetable Glycerin (VG) is less popular when compared to Propylene Glycol (PG) base. It has much higher viscosity, which makes it a perfect base for vapers who love a thicker and higher density vapor cloud. It is easier on your throat which means it delivers less throat hit. Unlike PG base, Vegetable Glycerin contains preexisting flavor and sweetness. This means that in many cases the added flavoring will be diluted and final product (e-liquid) will be sweeter. When comparing Propylene Glycol (PG) vs. Vegetable Glycerin (VG) E-juices in terms of flavor intensity, Vegetable Glycerin (VG) tends to deliver duller flavors. Another negative aspect of VG base is gunk residue, because of high density and consistency of VG you will notice faster build up around your coil and inside walls of your e-juice delivery device. Furthermore, higher viscosity of Vegetable Glycerin (VG) typically requires more power and longer time to achieve optimal vaping temperature. When using in devices that employ polyfill and wick materials, allow for additional time after refilling for e-juice to be absorbed before starting to vape.
Vegetable glycerin is also known as vegetable glycerol. It is a carbohydrate that is usually derived from plant oils. It is used as a sweetener and as an ingredient in a number of cosmetic products. Vegetable glycerin is also used in place of alcohol to extract botanicals. Citation
Vegetable glycerin based E-liquid usually contain at least 80% and as much as 92% Vegetable glycerin. This is the ingredient that produces the smoke-like vapor when the e-cigarette is exhaled. Approximately 20% of all e-liquids on the market today are vegetable glycerin based. Vegetable glycerin typically produces more vapor production than propylene glycol, but has reduced throat hit. It is also slightly more viscous (thicker) and slightly sweeter then propylene glycol. Its increased thickness makes it a culprit in reducing the life of atomizers. Some vapers use a blend of vegetable glycerin and propylene glycol – most often 80-90% PG and 10-20% VG, and sometimes a 50/50 split VG to PG in their e-liquid.
