OCTYL PROPIONATE Usage And Synthesis

Description

Octyl propionate has a complex, waxy odor reminiscent of myrtle berries with a pineapple undertone. May be prepared by esterification of n-octanol with propionic acid.

Chemical Properties

Octyl propionate has a complex, waxy odor reminiscent of myrtle berries with a pineapple undertone.

Occurrence

Reported found in oil of hop and strawberry fruit.

Uses

Octyl propionate has been suggested as a supporting note in warm-herbaceous and floral herbaceous fragrance types, and it blends very well in Lavender, Lavandin, Rosemary, Juniperberry, Myrtle, Laurel and Bayleaf oils. Although its odor has very little in common with Myrtle, it lends a pleasant support of softness, and reduces the cineolic notes in Myrtle oil. It finds some use in flavor compositions, e. g. in Honey, Pineapple, various berry compositions, citrus complexes, Melon, Champignon, etc, but normally at very low concentrations - equal to 0.5 to 5 ppm in the functional product.

Preparation

By esterification of n-octanol with propionic acid.

Definition

ChEBI: Octyl propanoate is a carboxylic ester.

Taste threshold values

Taste characteristics at 10 ppm: sweet, estry, fruity and berry with a tropical, jamy note.
