Glycerin is also known as glycerol.
Glycerin is a clear liquid with a viscous consistency.
("Viscous" means very thick e.g. flows more like treacle than like water - but the term "viscous" conveys no information about colour or transparency).
Glycerin can be produced by hydrolysis of fats and mixed oils, e.g. as a by-product in the manufacture of soap.
What does glycerin do:
Glycerin has various uses, such as an emollient in some skin products, as a sweetening agent in some pharmaceutical products, and as a laxative (e.g. in the form of suppositories). The use of glycerin for its laxative effects is relevant to the digestive system.
