What is Vegetable Glycerin?
Vegetable glycerin is widely available in a number of plant oils, such as coconut, soy, and palm oil, and is the polyol molecule that forms the backbone of glyceride lipids. This colorless and odorless liquid has a sweet flavor and a viscous consistency when separated out from plant oils. Hydrolysis is the process by which glycerin is made, in which the oils are subjected to intense pressure and temperature, at which point the ester bonds of the lipids break, and the glycerin is absorbed by the water present. Distillation then separates out the constituent parts, leaving pure glycerin as the final product!
Glycerin, also known as glycerol, has a number of unique qualities, which has made it a popular ingredient in the cosmetic and skincare industry, as well as in food production and alternative medicine fields.
