Also known as glycerol. It is a colorless, transparent, viscous liquid that is odorless and sweet. Glycerin and concentrated glycerin are listed in the Japanese Pharmacopoeia. A 50% aqueous solution is used as an enema to treat constipation, and is also used as a base for suppositories. Because it has moisturizing and demulcent properties, it is often used as an ingredient in ointments, creams, lotions, and other liniments to protect and soften the skin and mucous membranes. It is also used as an injection for treating cerebral edema and for lowering intraocular and cerebrospinal pressure. In the Japanese Pharmacopoeia, it is included in potassium glycerin solution, which is used to treat cracks and chapped skin, compound iodine-glycerin, which is applied as a bactericide and disinfectant, dental iodine-glycerin, phenol-zinc oxide liniment, and dental triozinc paste.
