List of Common E-Cigarette Ingredients

Many people wonder what could be found in every stick of electronic cigarettes including the components that add a distinct flavor to each liquid nicotine. To learn more about the composition of these e-cigs, you may want to read along to discover more about the components of these devices.

Propylene Glycol and Glycerol

About 80 to 90 percent of e-cig ingredients include propylene glycol and glycerol. Propylene glycol is an FDA-approved substance that is used in various applications such as saline solutions, pharmaceutical products, food additive (E1520), and solvent for food flavorings and food colors. Quite similarly, glycerol or glycerin is an odorless and viscous liquid that tastes sweet and is low in toxicity. When used in beverages, it serves as a moisturizer and sweetener. It may also be used as a filler in commercial low-fat food products such as chips and cookies, and it can help thicken the quality of most liquors. Glycerin is also included in most cough syrups, toothpaste, skin care products, and hair care solutions.

Since 1942, propylene glycol has been included in the list of non-official remedies and major ingredient in several pharmaceutical products. It also does not cause any types of sensitization, and there are no evidences of this subtance being genotoxic or carcinogenic.


This is an alkaloid typically found in the leaves of tobacco. It serves as an anti-herbivore that help eliminate insects. When used in low concentrations such as in cigarettes, it serves as a stimulant. Thus, it is responsible for the addiction of most cigarette smokers, which make them hooked on smoking. Over the years, the nicotine content in tobacco has increased. In fact, there is a study that shows an increase of up to 1.6 percent annually in terms of the composition of this substance in cigarettes.


Electronic cigarettes contain a wide range of food-grade flavoring substances to create distinct taste in their cartridges. In fact, these are the same kind of flavor additives used in sodas and candies, as well as in various packaged food products. You can find a number of electronic cigarettes that come in interesting flavor such as chocolate, coffee, peach, green tea, and even pina collada! These flavors are made possible with the help of these safe and risk-free flavorings added in liquid nicotine.

Ethyl Acetate

A very small percentage of all ingredients used in electronic cigarettes is made up of ethyl acetate. This is generally used as a dilutant and solvent, and most manufacturers favor this substance because it is inexpensive, has low toxicity, and comes with an agreeable odor. In fact, tea leaves and coffee beans are decaffeinated with the help of this solvent. Ethyl acetate is also the ester of the acetic acid and ethanol.

Malic Acid

Malic acid is a type of dicarboxylic acid that is commonly found in tart-tasting or sour foods. When it is ingested, it produces a mild and persistent sour taste in the mouth. The body also produces this acid as part of the natural citric acid cycle. In most cases, malic acid is used in food products such as potato chips and candy. Instead of citric acid, most sour candies use malic acid as one of the ingredients because of the more intense sour taste. Vinegar-flavored potato chips also use malic acid for greater aroma and flavor. However, too much consumption of foods including malic acid is not advisable because it can cause the inside of your mouth to become sore.


Also called methyl vanillin, this substance is one of the main components of the vanilla bean extract. It may also be found in roasted coffee, and synthetic vanillin may be used in some foods and beverages instead of natural vanilla.

Linalyl Alcohol

More than 200 plant species produce the substance linalyl, particularly those that come from the Lamiaceae family such as scented herbs and mints, Rutaceae including citrus fruits, and Lauraceae or cinnamon, laurels and rosewood. Linalyl alcohol is typically used to add a distinct scent to perfumed lotions and skin care products.

Acetylepyrazine and Menthol

Acetylepyrazine is one of the compositions of food flavoring used in chocolates and baked foods. On the other hand, menthol may be made synthetically, or it can be obtained from essential mint oils such as peppermint. It has a waxy texture, and it may be white or clear in color. When placed at room temperature, the substance remains solid, and it comes with a counter-irritant and anesthetic quality. Thus, it may also be used as a relief for minor throat irritation.
