Lauric acid is a saturated carboxylic acid with the molecular formula C12H24O2 and the linear formula:CH3-(CH2)10-COOH0. Lauric acid is derived from the alkane n-dodecane.
Lauric acid occurs naturally as a glycerol ester in coconut oil (see oleum cocos) and laurel oil (oleum lauri - see laurel oil below), as well as a cetyl ester in spermaceti.
Lauric acid has a melting point of 43.7ºC and a boiling point of 227ºC. It is soluble in ether and ethanol and insoluble in water.
The esters and salts of lauric acid are called laurates (systematically also dodecanoates).
