The animal that produces natural musk is the male musk deer, a small, shy deer found in the mountain forests of Asia. Musk has been prized in perfumery for centuries because of its warm, lasting scent.
How Musk Is Produced
Natural musk comes from the musk pod, a preputial gland located in a pouch under the skin of the male deer’s abdomen.
The secretion is thought to play a role in marking territory and attracting females during the breeding season.
Freshly collected musk is a waxy, reddish-brown substance that turns dark and granular as it dries.
In perfumery it is usually prepared as a tincture in pure alcohol and left to stand for several months before use.
Why Perfumers Valued It
Musk was valued for two reasons: its rich, animal-like fragrance and its ability to act as a fixative. A fixative slows the evaporation of other scent ingredients, so the perfume lasts longer on skin. For this reason, natural musk was long used in some of the highest grades of perfume.
The Impact on Musk Deer
Because the pod can only be obtained from the male deer, demand led to heavy hunting and a sharp decline in musk deer populations in regions such as the Himalayas and parts of Siberia. Several musk deer species are now considered threatened, and they are protected under international trade rules as well as under national wildlife laws in countries such as India. Hunting still occurs illegally, which keeps conservation a serious concern.
The Shift to Synthetic Musk
Chemists identified muscone, the compound largely responsible for musk’s odour, and learned to make it and similar compounds artificially.
Synthetic musks now supply almost all of the musk used in modern perfumes, soaps, detergents and cosmetics.
These alternatives are cheaper, more consistent in quality and do not require harming animals.
Plant-based and lab-made options are also used in fragrances marketed as cruelty-free.
Other Animals Linked With Musky Scents
Some other animals, such as the civet, produce strong musky secretions that were used in perfumery in the past, but the true source of traditional musk remains the male musk deer. The musk ox and the muskrat carry the word in their names because of their scent, though they are not sources of perfume musk.
Key Takeaway
Natural musk comes from the male musk deer’s musk pod. Today, because of conservation concerns and the availability of synthetic options, most musk in perfumes is made in laboratories rather than taken from wild animals.
