Veg Glycerin or vegetable glycerin, as the name implies, is sourced from plant oils. Propan-1,2,3-triol in IUPAC nomenclature, its chemical formula is C3H8O3 while its CAS registry number is 56-81-5. Glycerin is derived from the Greek word glykys meaning sweet -- as characterized by its taste, and is colorless and viscous. It was discovered by K.W. Shele in 1779 as a by-product of olive oil saponification. Glycerin was first used in the cork and glue process but later branched out in textiles and ink manufacturing. It was later discovered to be vital for dynamite production by Alfred Nobel that it became a crucial product especially during the two world wars.
Glycerin is naturally occurring in animals and plants, including humans. It can either be sourced naturally or synthetically (through petroleum). Manufacturing process is usually seen through saponification: 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 pure form.
Glycerin has a boiling point of 290°C and has a melting point of 20°C. It is miscible in water, ethanol, acetone, and DMSO while immiscible in ether and benzene. It has a specific gravity of 1.26 (20/20°C) and a vapor density of 3.17 (AIR=1).
Glycerin’s kindling point is at 393°C while its flash point is at 177°C. It is highly flammable but doesn’t have any spontaneous combustibility, self-reactivity, and ignitability. It should be taken away from strong oxidizing agents such as chromium trioxide, potassium chlorate, or potassium permanganate to avoid explosion. Glycerin is considered stable under normal storage and handling conditions, though it should be handled carefully because it is hygroscopic.
Veg Glycerin of Chemicals Direct is derived from natural sources like palm and coconut and therefore safe to be used for food, beverages, and medical preparations. Our vegetable glycerin is packaged in compliance with standards and legal requirements set by the FDA‘s Good Manufacturing Practices (GMP). Product is Kosher and USP grade so you are assured of its safety and quality. All products are in stock and ready to be shipped within the day.
