Palmitic acid ethyl ester

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.

The Uses of Palmitic acid ethyl ester

A fatty acid found in Amaranth oil; it shows inhibitory activity.

The Uses of Palmitic acid ethyl ester

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.

What are the applications of Application

Ethyl palmitate is an ethyl ester of palmitic acid

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.
