• Uses: Pharmaceutical Industry Ethyl oleate is utilized as an ingredient for the preparations of pharmaceutical drugs that involves lipophilic substances such as steroids. Due to its quick degradation of the digestive system, ethyl oleate is employed as a way for intramuscular drug delivery by compounding pharmacies. In some cases, the compound is used in the preparation of day-to-day doses of progesterone in the sustenance of pregnancy. Transport Industry It is used in the transport industry as a lubricant and as a plasticiser. It is also used as a planting agent and for treating surfaces. Food Industry Ethyl oleate is used as a food additive and is regulated by the Food and Drug Administration. It is also used as a flavouring agent in food. Ethyl oleate is a flavoring and fragrance agent. It was obtained by the hydrolysis of various animal and vegetable fats and oils. Usually used to prepare the oily phase of self-microemulsifying drug delivery system (SMEDDS) for tacrolimus (Tac).
• Description: Ethyl oleate is a fatty acid ester formed by the condensation of oleic acid and ethanol. It is a colorless to light yellow liquid. Ethyl oleate is produced by the body during ethanol intoxication. Ethyl oleate is used as a solvent for pharmaceutical drug preparations involving lipophilic substances such as steroids. It also finds use as a lubricant and a plasticizer. Ethyl oleate is regulated as a food additive by the Food and Drug Administration under "Food Additives Permitted for Direct Addition to Food for Human Consumption", 21CFR172.515. Ethyl oleate has been identified as a primer pheromone in honeybees. Ethyl oleate is one of the fatty acid ethyl esters (FAEE) that is formed in the body after ingestion of ethanol. There is a growing body of research literature that implicates FAEEs such as ethyl oleate as the toxic mediators of ethanol in the body (pancreas, liver, heart, and brain). Among the speculations is that ethyl oleate may be the toxic mediator of alcohol in fetal alcohol syndrome. The oral ingestion of ethyl oleate has been carefully studied and due to rapid degradation in the digestive tract it appears safe for oral ingestion. Ethyl oleate is not currently approved by the U.S. Food and Drug Administration for any injectable use. However, it is used by compounding pharmacies as a vehicle for intramuscular drug delivery, in some cases to prepare the daily doses of progesterone in support of pregnancy. Studies which document the safe use of ethyl oleate in pregnancy for both the mother and the fetus have never been performed.

Epoxidation of Fatty Acid Esters with Aqueous Hydrogen Peroxide in the Presence of Molybdenum Oxide-Tributyltin Chloride on Charcoal Catalyst

10.1246/bcsj.59.3941

Yasushi Irol, Masami INouE, and Saburo Enomoro, investigate the epoxidation of fatty acid esters using 30% aqueous hydrogen peroxide in the presence of a molybdenum oxide-tributyltin chloride on charcoal catalyst in 2-propanol at 50°C. The study demonstrates that various fatty acid esters, including ethyl erucate and ethyl oleate, achieve good yields of 77% and 76%, respectively, while ethyl elaidate, a trans-form, yields only 40%. The epoxidation process selectively maintains the double bond configuration and is more effective for cis-forms due to steric effects. The study also explores the epoxidation of vegetable oils such as rapeseed oil, olive oil, soybean oil, cottonseed oil, corn oil, and linseed oil, with oxirane oxygen contents ranging from 3.5% to 5.3%. The results indicate that the presence of specific fatty acids, like erucic acid in rapeseed oil, significantly influences the epoxidation yield. The study concludes that the use of 30% aqueous hydrogen peroxide is a practical and safer alternative to organic peroxy acids for epoxidation, and the catalyst can be easily separated by filtration.
