GLYCERIN

Last update on Feb 13, 2026

Glycerin (also glycerine) is one of the most frequently used ingredients in the cosmetic industry. The reason is its effectiveness and versatility. Also known as Glycerol, Glycerin is an odorless and colorless liquid that remains non-toxic and anti-allergenic. It works well with cosmetics as Glycerin is a humectant, i.e., it draws moisture from the air and deeper layers of the skin – thus making it an excellent moisturizer.

Origin

Karl Wilhelm Scheele, a Swedish chemist, accidentally discovered Glycerin while heating a mixture of olive oil and lead oxide in 1779. Today, it can be entirely vegan if derived from plants. It is obtained from plant oils such as coconut, soy, and palm oil. The latest way of making Glycerin has been via petroleum. This type of artificial synthetic glycerin is made in the laboratory. Nevertheless, plant-derived glycerin is still preferred since it is much cheaper to manufacture.
