Chemistry:Demulcent
A demulcent (derived from the Latin: demulcere "caress") is a mucilaginous or oleaginous preparation[1] that forms a soothing protective film over a mucous membrane, relieving minor pain and inflammation of the membrane.[2] However, they generally help for less than 30 minutes.[3]
Demulcents are sometimes referred to as mucoprotective agents. Demulcents such as pectin, glycerin, honey, and syrup are common ingredients in cough mixtures and cough drops.[4]
Examples
Natural demulcents include slippery elm, pectin, licorice-root and marsh-mallow.
Synthetic demulcents include methylcellulose, propylene glycol, and glycerin.
