We often see the content of VG and PG in the ingredients of cigarette oil. For those who have just come into contact with e-cigarettes, they are not very clear about what VG and PG mean, and what is the difference between them. Today, Xiaobian will popularize this professional knowledge with everyone.
1. What is VG?
VG, also known as “Vegetable Glycerin”, “glycerin” (Vegetable Glycerin), is a colorless, sweet, clear and transparent viscous liquid, odorless itself, with warm sweetness. The national standard is called glycerin, which can absorb moisture from the air and can be used as a solvent, lubricant, pharmaceutical and sweetener. It is a basic material widely used in food, cosmetics and medicine. VG belongs to the ethanol group of chemicals, although e-cigarette oil is called “oil”, but it is not real oil at all, and can not cause any diseases such as liposuction pneumonia; When heated, they produce steam, allowing them to be inhaled.
VG has a slightly sweeter taste and is much thicker than PG. High VG liquids are more mellow than PG and are particularly suitable for producing large smogs. While nicotine and flavors are typically blended with PG, some manufacturers are offering alternative VGS to achieve a 100% pure VG blend.
2. What is PG?
PG is the abbreviation of propylene glycol. PG is manufactured by hydration of propylene oxide. PG is much thinner than VG and produces much less smoke. But PG has a strong throat-to-throat sensation, and many users like this feeling.
PG has been recognized as a safe food additive by the FDA. However, from the reaction of e-cigarette users, some users have allergies and other adverse reactions after using PG-containing tobacco oil. Allergies are large and small, light throat discomfort, heavy body itching, accompanied by dizziness, nausea symptoms. If allergic reactions occur, such people should choose VG’s fume oil.
VG Benefits: Smoke, health, less allergic reactions, natural sweetness, throat comfort. Disadvantages: the smoke oil is thick, not easy to drain oil, does not touch the throat, sweetness may overpower the fragrance, dry mouth or phlegm.
PG advantages: easy to blend flavor, strong throat feeling, good fume oil. Disadvantages: The liquid needs to be sweetened with sweeteners.
