You may be wondering exactly what is VG and PG? Vegetable Glycerin and Propylene Glycol is the main ingredients in your e-juice. Most e-juice only have 3-4 different types of ingredients. Everything you need to know about vaping with VG and PG will be covered in this blog!
Vegetable Glycerin is one of the main contents in e-juice, it is a viscous liquid with no color or taste. The FDA considers VG as GRAS (Generally Recognized as Safe) for human ingestion. VG is also found in most low carbohydrate foods for sweetness and moisture. Most if not all premium e-liquids are produced with 99% USP food grade VG.
In early stages VG is produced from different types of oil, generally plant oils, soy, coconut oil, and palm oil. Through a process called Hydrolysis, oils are placed under pressure, temperature, and water. When hydrolysis occurs the glycerin splits from fatty acids and is absorbed by water. At this stage, the VG is not 99% USP food grade, it will undergo further distillation for purity.
In vaping, VG is used for cloud production. The higher percentage of VG to PG, the thicker the clouds. Cloud chasers generally use 80% VG or higher e-liquid for the most vapor production.
Propylene Glycol is the other side of e-liquid blends. PG has a less viscous texture and runnier than VG.In vapes it is mainly used to deliver flavor and throat hit with your vape. It is also used as a food additive to help retain moisture and a bonding agent for different ingredients. You can find it in salad dressing, cake mix, and food coloring.
PG is produced from propylene oxide for food-grade use. Depending on the use of the propylene glycol, different manufacturers use two types of processes. Non-catalytic high-temperature process and a catalytic method. The difference's are minute, two of the main differences are temperature and ion exchange or a small amount of acid or alkali.
Over the years VG and PG mix has fluctuated due to trends. When e-cigarettes were first starting out most blends were 50% VG and 50% PG. Then cloud chasing came along and consumers generally preferred e-juice that was 70% or above. Manufacturers had to adapt to the trends and created e-liquid that delivered the same taste but with a less PG ratio. Below is a chart of different blends manufacturers use to deliver different types of flavors in your vape! We will go more in depth in a future blog.
