Nicotine, propylene glycol, vegetable glycerin, and food-grade flavoring concentrates are common ingredients in e-juices. These ingredients are considered safe by the FDA when used properly. However, some researchers are concerned about the dangers of these ingredients in vape in UAE. To better understand their role, let’s look at what they do.


Nicotine is a powerful drug that is found in cigarettes and vaporizers. It increases the release of dopamine in the brain, a neurotransmitter that helps you feel good. This substance also raises your blood pressure and can cause diabetes. If you are thinking about switching to a vape pen or vaporizer, it is important to consider the risks and benefits of nicotine.

Propylene Glycol:

PG is a clear, tasteless, and odorless liquid used as the carrier liquid in vape juices. It is a versatile substance that has many uses in the chemical, food, and pharmaceutical industries. It is also used in vapes because of its emulsifying qualities, which keep the other ingredients suspended in the e-liquid, allowing the atomization process to occur at lower temperatures. This substance also carries nicotine to the user’s lungs.

Flavoring concentrates:

Flavoring concentrates are liquids that contain the same essential ingredients as e-juice. The major difference is that they don’t contain nicotine. They are diluted in PG and are intended to be used as a replacement for mixing flavorings and replicating the flavors of other products. Flavoring concentrates are used in the production of e-liquid and are generally 10 percent of the total e-liquid content.

Flavoring concentrates come in various potencies and can vary in their flavor profiles. Some concentrates are extremely potent, while others are not. Flavor and Inawera are well-known for their potent concentrates, which can range from five to ten percent.


Glycerin is an ingredient commonly found in vape liquids. The FDA considers glycerin safe. Its properties make it an excellent choice for vaping. It has little or no odor is colorless and has a mild, sweet taste. But it can have health risks. In large doses, it can be harmful to the lungs.

Many e-juices also contain propylene glycol, which is used to thicken the liquid. Some studies have shown that propylene glycol is harmful when heated and inhaled. The FDA has not banned PG, but they recommend that you always read the ingredients label before buying.
