Lauric acid - Laurinsan (English spelling) lauric acid

A saturated fatty acid. Also known as dodecanoic acid. It is found in vegetable oils such as coconut oil and bay laurel oil as lauric acid, a type of glyceride. The name lauric acid comes from the scientific name for bay laurel , Laurus nobilis L. It is obtained by esterifying the mixed fatty acids of coconut oil, distilling them under reduced pressure, and then saponifying them. It appears as white needle-like crystals and is insoluble in water, but is highly soluble in organic solvents such as ether and benzene. It is the raw material for lauryl alcohol, which is used in detergents and surfactants.
