| Hazard Information | Back Directory | [Chemical Properties]
Cyclopentadecanolide occurs in small quantities in,
for example, angelica root oil. It forms colorless crystals (mp 37–38°C) with a
delicate, musk-like odor. | [Chemical Properties]
white crystalline low melting solid | [Chemical Properties]
ω-Pentadecalactone has an extraordinarily persistent, musk-like odor. | [Occurrence]
Originally reported found in the essential oil from angelica roots. | [Uses]
As a fixative in perfumery. | [Application]
Cyclopentadecanolide gives highly interesting effects when applied to certain flavors,
e. g. alcoholic beverages, dentifrice flavors etc.
There is very often a unanimous preference
for the flavor that is properly treated with the
hctone. Concentration in such flavors may be about
0.02 to 1.50 ppm calculated upon the finished
consumer product. However, it should be
kept in mind, that dentifrices are flavored at
extremely high concentration (about 100) and
it may therefore ghe an underestimated evaluation of the power of this Lactone, The most
frequent abuse of Cyclopentadecanolide is
that of over-dosage. It is also used extensively in Berry flavors, Liquor, Wine, Brandy, Fruit, Nut, Vanilla copositions, etc. | [Definition]
ChEBI: Cyclopentadecanolide is a macrolide. | [Preparation]
The main industrial syntheses start from compounds produced
from cyclododecatriene: either by ring expansion of cyclododecanone or
by depolymerization of polyesters of 15-hydroxypentadecanoic acid (from
1,12-dodecanediol). | [Aroma threshold values]
Detection: 1 to 4 ppb | [Taste threshold values]
Taste characteristics at 75 ppm: vanilla bean, powdery helioropine, creamy and licorice. | [Synthesis Reference(s)]
