Ethyl linoleate (ELA) is an essential fatty acid used in many cosmetics for its anti-inflammatory properties. It inhibits the action of the reactive species of oxygen released by neutrophils due to an excess of bacteria, and prevents the hyperkeratinization induced by a lack of linoleic acid. Though there are few reports stating the antiinflammatory activity of ELA, the mechanism by which ELA exhibits anti-inflammatory activity remains unclear. An aqueous emulsion of ethyl linoleate can be used as parenteral injection for curring ailments where a high plasma-cholesterol level of the blood is indicated. Improvements in liver function tests during the administration of ELA were noticed in almost all cases with a few aggravated exceptions. The administration of ELA can expect the satisfactory response to the patients both with liver cirrhosis and with chronic hepatitis.
