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 then 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 e-smokers 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.
