Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. Oleic acid as its sodium salt is a major component of soap as an emulsifying agent.
Red oil (oleic acid, elaine) and stearic acid are the two fatty acids most generally bought for soap making. It is also obtained when sebacic, stearic and oleic acids are oxidized with nitric acid. The oleic acid, being liquid at ordinary temperature, together with some stearic and palmitic acid, is thus pressed out.
