What Is Glycerin


Glycerin is a viscous, odorless, colorless, and sweet liquid usually added in toiletry and medical preparations. Glycerin's most common application is in soap making, although it is also used in explosives manufacturing, in the form of nitroglycerin. Soluble in water and alcohol, it boils to 290°C while it freezes to a paste.

How do you make glycerin?

Glycerin is naturally occurring in plants and animals, including humans. It accumulates either subcutaneously or as lipid formations in muscles. There are two types of glycerin: natural glycerin which is sourced from plants such as palm and synthetic glycerin which is sourced from biodiesel synthesis. To process glycerin naturally, the crude substance derived from fat hydrolysis is first refined and condensed into an aqueous solution (known as sweet water), then further distilled and refined until the solution arrives in its final form.
