There are times that it may also include water or dehydrogen oxide, however these are just included to make variations of the vape.
Let us talk about these ingredients. First is the vegetable glycerin, which is extracted from palm plants. This ingredient is used as food additive or preservative. It doesn’t have any odor and it is mainly used for lotions, cosmetics and medications. Next ingredient is the Propylene Glycol, it is a substance that is commonly used for medical products, food and even in toothpaste.
It is being used by people for a long time and it has been proven that being exposed to this substance for a long-time is not harmful. Vapers should drink a lot of water because this ingredient can absorb a lot of water causing mild dehydration.
Propylene glycol does not generate that much smoke or vapor like vegetable glycerin, however it is considered as a strong kind of vapor. There are people who find PG as harsh so they try to move to VG e-juice. Vape juice with 50% PG is made for beginners.
It is made for e-cigarette with atomizers. This has 1.0 ohms and above resistance levels. VG produces safe and more vapor for inhalation.
Propylene glycol, though has better taste compared to VG. This is the reason why vape juice online with high VG still has a little PG. There are varied amounts of PG and VG in every vape juice. In other words, PG gives the flavor and VG produces the vapor.
