There is a wide range of ingredients used to make e-juice or what is known as e-liquids. Each of them plays an important role in creating different vaping experiences. A vaporized mist is released after the e-juice is adequately heated. That mist is then inhaled like a typical cigarette smoke. With that, the five basic liquid ingredients include vegetable glycerin, propylene glycol, flavorings, nicotine and water. It is useful to note that most e-juices contain both vegetable glycerin and propylene glycol. Next, let’s take a further look at the mentioned ingredients.
When vegetable glycerin is the primary ingredient in an e-juice, distilled water is used as a diluent. Water helps decrease the viscosity of the mixture. Water is often needed to prevent build-up and ensure a smooth consistency.
Nicotine has a bad reputation. However, it is 100% safe if consumed in normal doses. Nicotine can naturally be found in tobacco leaves and is considered to be a stimulant like caffeine. Did you know that it is also present in other plants such as potatoes and tomatoes? Next, the nicotine used in vape liquids is pharmaceutical grade and pure. This means that its level of concentration is also controlled. Vapers know how much nicotine they are getting. Most e-juice makers offer their vape juices with varying concentration levels of nicotine.
This colorless, tasteless and odorless alcohol is generally used as an anti-freeze element. It is an organic compound made in laboratories and is often considered safe for consumption and topical applications. In fact, FDA has approved the ingredient for several purposes. For example, it is utilized in the production of pharmaceutical goods, skin care products and theatrical smoke machines. It is also utilized as a food additive for various products that are consumed daily. In e-juice liquids, propylene glycol contributes to vapor production by serving as a base. It is also known to deliver a strong throat hit.
Another base ingredient in e-juice is vegetable glycerin. It is extracted from vegetable plant oils and is considered to be 100% safe and natural. Compared to propylene glycol, vegetable glycerine is thicker. That’s why, it can cause a build-up of phlegm in the mouth and throat. However, it produces a smoother and weaker throat hit. Vegetable glycerin has a slightly sweet taste that tends to overpower the flavors of an e-juice. Other uses of the sugar alcohol include being a low-glycemic texture enhancer, preservative and sweetener.
Flavorings are a key element that makes vape e-juices satisfying and unique. E-juice makers tend to maintain secrecy over the ingredients used. However, most of the flavorings are made from FDA-approved and naturally occurring, food-grade additives. Here are a few flavor additives:
- Acetylpyrazine: It can replicate the taste of beef, pork, wheat bread, popcorn, coffee, cocoa and almonds.
- Vanillin: As a primary component of vanilla bean extract, vanillin is used in desert e-liquids. It is either artificially made from lignin or naturally extracted from vanilla pods.
- Malic Acid: Fruity e-juices contain this organic compound. It gives the e-juice a tart-like and sour taste. It is also added to certain cola drinks to lower pH levels.
