There are several ways of preparing the commercial musk, and the best method is to dry the pod by sunning and airing immediately after it is taken from the animal.

No other natural substance has such a complex aroma associated with so many contradictory descriptions; it is usually described abstractly as animalistic, earthy and woody or something akin to the odor of baby's skin.

Today, the trade quantity of the natural musk is controlled by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (

Synthesis

Since obtaining the deer musk requires killing the endangered animal, nearly all musk fragrance used in perfumery today is synthetic, sometimes called "white musk". They can be divided into three major classes: aromatic nitro musks, polycyclic musk compounds, and macrocyclic musk compounds. The first two groups have broad uses in industry ranging from

s. The detection of the first two chemical groups in human and environmental samples as well as their carcinogenic properties initiated a public debate on the use of these compounds and a ban or reduction of their use in many regions of the world. Macrocyclic musk compounds are expected to replace them since these compounds appear to be safer.
