What is Ethyl myristate?

Description

Myristic acid is a saturated fatty acid commonly found in animal and vegetable fats that is frequently used in cosmetics, soaps, perfumes, and flavorings. It increases low density lipoprotein cholesterol making it one of the most hypercholesterolemic of the saturated fatty acids. Myristic acid ethyl ester is a more hydrophobic form of the free acid. It is a marker of excessive ethanol consumption that can be isolated from the hair of an individual.

Chemical properties

Clear colorless liquid, solidifying in the cold

Chemical properties

Ethyl myristate has a mild, waxy, soapy odor reminiscent of orris.

Occurrence

Reported found in apricot, grape, pear, capsicum, beef, beer, rum, tea, guava, Vitis vinifera, ginger, Gruyere cheese, blue cheese, boiled mutton, cognac, whiskey, sparkling wine, cocoa, coconut meat, mango, corn oil, elderberry and mastic gum leaf oil.

The Uses of Ethyl myristate

Ethyl myristate may be used as an analytical standard for the determination of the analyte as an alcohol biomarker in dried blood spots and hair samples by chromatography based techniques. Ethyl myristate may also be used as an analytical standard in the determination of the analyte in selected beer flavors by stir bar sorptive extraction and solvent back extraction.

The Uses of Ethyl myristate

Ethyl myristate is a labeled component from essential oil of natural hawthorn perfume. It is also frequently used in cosmetics, soaps, and flavorings.

What are the applications of Application

Myristic Acid ethyl ester is a 16 carbon saturated fatty acid

Definition

ChEBI: A long-chain fatty acid ethyl ester resulting from the formal condensation of the carboxy group of myristic acid with the hydroxy group of ethanol.

Preparation

By esterification of the acid with ethyl alcohol in the presence of gaseous HCl.

Aroma threshold values

Detection: 4 ppm

Taste threshold values

Taste characteristics at 60 ppm: sweet, waxy and creamy.

General Description

Ethyl myristate is a fatty acid ethyl ester (FAEE) that can be formed in the body due to non-oxidative metabolism of ethanol. It also occurs in vegetable oils. Ethyl myristate, along with other FAEEs are used as alcohol markers in hair.

Safety Profile

Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.
