Monolaurin, also known as glycerol monolaurate, glyceryl laurate or 1-Lauroyl-glycerol, is a monoglyceride. It is the mono-ester formed from glycerol and lauric acid. Its chemical formula is C15H30O4.


Monolaurin is most commonly used as a surfactant in cosmetics, such as deodorants. As a food additive it is also used as an emulsifier.


Monolaurin is found in coconut oil and naturally occurs in human breast milk.[1]


Monolaurin has antibacterial, antiviral, and other antimicrobial effects in vitro.[2][3][4][5][6][7] It may therefore be useful in the treatment or prevention of various infections, but its clinical usefulness has not been established.
