| | Palmitic acid ethyl ester Usage And Synthesis |
| Description | Palmitic acid ethyl ester, also known as ethyl palmitate, it the ethyl ester form of palmitic acid. It can be used as a hair- and skin-conditioning agent. It has been shown that the combination between palmitic acid ethyl ester and cobra venom factor can enhance the survival of heterologous erythrocyte. Recent study has also demonstrated the potential anti-inflammatory activity of palmitic acid ethyl ester in several animal models.
| | Chemical Properties | clear colorless oily liquid after melting | | Chemical Properties | Ethyl palmitate has a mild, waxy sweet odor. It is nearly tasteless and has a creamy mouthfeel. | | Occurrence | Reported found in mutton, rye bread, rice, bourbon, vanilla, red sage, lemon balm, bilberry, Parmesan cheese,
maple syrup, Jamaican rum, whiskey, grape wine, cognac, cocoa, green tea, mango, corn oil and mastic gum leaf oil. | | Uses | Ethyl palmitate acts as a lubricant on the skin?s surfaces in order to get a soft and smooth appearance. It increases cytosolic Ca2+ concentration leading to pancreatic acinar cell injury due to excessive consumption of ethanol. | | Uses | A fatty acid found in Amaranth oil; it shows inhibitory activity. | | Definition | ChEBI: A long-chain fatty acid ethyl ester resulting from the formal condensation of the carboxy group of palmitic acid with the hydroxy group of ethanol. | | Aroma threshold values | Detection: 2 ppm | | Taste threshold values | Taste characteristics at 30 ppm: waxy, fruity, creamy and fermented with a vanilla, balsamic nuance. | | Synthesis Reference(s) | Tetrahedron, 48, p. 8775, 1992 DOI: 10.1016/S0040-4020(01)89450-3 | | General Description | Ethyl palmitate is a one of the major volatile compounds found in cooked rice and Luzhou-flavor raw liquor. It occurs naturally in licorice root and chamomile. | | Synthesis | Synthesized by immobilized lipase-catalyzed alcoholysis and esterification in organic solvents. | | References | Beste, Russell D, and R.
