Glycerin is often used in electronic cigarettes to create the vapor. Glycerin, along with propylene glycol, is a common component of e-liquid, a solution used with electronic vaporizers (electronic cigarettes). This glycerol is heated with an atomizer (a heating coil often made of Kanthal wire), producing the aerosol that delivers nicotine to ...
Propylene glycol, vegetable glycerin, [27] or a mixture of both, are the main ingredients in e-liquid used in electronic cigarettes. They are aerosolized to resemble smoke and serve as carriers for substances such as nicotine and flavorants. [28]
The structure below shows the major component of castor oil which is composed of the tri-ester of rincinoleic acid and glycerin: Major component of castor oil. Other vegetable oils - such as soy bean oil, [3] peanut oil, and canola oil - contain carbon-carbon double bonds, but no hydroxyl groups
Stearin is obtained from animal fats created as a byproduct of processing beef.It can also be found in tropical plants such as palm. It can be partially purified by dry fractionation by pressing tallow or other fatty mixtures, leading to separation of the higher melting stearin-rich material from the liquid, which is typically enriched in fats derived from oleic acid.
Ethanol has the advantage of being an excellent solvent for both acidic and basic (alkaline) constituents. A tincture using glycerine is called a glycerite. Glycerine is generally a poorer solvent than ethanol. Vinegar, being acidic, is a better solvent for obtaining alkaloids but a poorer solvent for acidic components.
Vegetable oils and animal fats are the traditional materials that are saponified. These greasy materials, triesters called triglycerides, are usually mixtures derived from diverse fatty acids. In the traditional saponification, the triglyceride is treated with lye, which cleaves the ester bonds, releasing fatty acid salts (soaps) and glycerol.

Monoglycerides and diglycerides are types of glycerides both naturally present in food fats, [2] including various seed oils; [3] however, their concentration is usually low and industrial production is primarily achieved by a glycerolysis reaction between triglycerides (fats/oils) and glycerol, [4] followed by purification via solvent-free molecular distillation.
