E-Liquid: Components of E-Liquid - Substances of E-Liquid
This article is about the components or ingredients of an E-Liquid. Essentially, E-Liquids consist of propylene glycol, glycerin, food flavors and, optionally, nicotine. In the following, we will get to know the individual components more closely.
Propylene glycol is a clear, colorless liquid approved in the EU as a food additive, which can be easily bound with water. The propylene glycol is formed by hydrolysis of the substance propylene oxide. In general, propylene glycol is used, for example, in hygiene articles such as toothpastes, skin creams, but also in the pharmaceutical industry in many medicinal products. The propylene glycol is also characterized by the ability to provide a better solubility to different substances. When the e-cigarettes are used, the propylene glycol ensures the formation of the vapor.
Glycerin is an odorless and colorless liquid that has a sweet taste. Gylcerin is considered a food additive and is used, among other things, as a moisturizer. Glycerol is, for example, contained in chewing gums or also in cosmetic articles and, like the propylene glycol (see above), has the property of allowing itself to bind well with water. When the e-cigarettes are used, the glycerin condenses the vapor and ensures that it does not volatilize so quickly.
Flavors are found in numerous foods. Without flavors the steaming of an e-cigarette certainly would not be enjoyable. Of course, the tobacco taste plays a corresponding role in the traditional cigarettes, but the e-cigarettes are the flavors that make the steaming special. The aroma contained in the e-liquid determines the taste of the steam.
