Description
An unsaturated fatty acid (C18) that is a component of many vegetable oils such as linseed, soybean, corn, sunflower, safflower, poppy seed, and perilla. Linoleic acid is one component that makes an oil a 'Drying oil'. The two double bonds in linoleic acid readily oxidize in air to produce a hardened, insoluble film. Pure linoleic acid added to paints, coatings, lacquers, and vitamins (as a food supplement).
Synonyms and Related Terms
