What Is Musk Scent? Musk in Perfume, From Deer Glands to Clean Laundry

Musk in a modern perfume is almost always a lab-made molecule, and there are dozens of them. Some smell of clean laundry, some of powder, some of warm skin. What they share is an old job: making a perfume feel soft, close and lasting.

(No, not that Musk.)

Where Does Musk Come From?

Originally, from a deer. The male musk deer, found from Afghanistan to northern Vietnam, has a gland under the skin of its abdomen that it uses to mark territory. Hunters cut out the pod and dried it, and the dark grains inside were steeped in alcohol to make a tincture for perfume. The word goes back through Persian mushk and Greek moskhos.

Raw musk smells nothing like what we now call musky. It’s harsh and animal on its own, and only becomes warm and sensual when it’s diluted far down. Hunting cut the deer’s numbers so sharply that all musk deer species are now protected under CITES, and natural musk has been out of mainstream perfumery for decades.

How Did Chemists Replace It?

In three waves, each named after the shape of its molecules.

Family	First made	Examples	Smell
Nitro musks	1888	Musk ketone, musk xylene, musk ambrette	Sweet, powdery, old-fashioned
Polycyclic musks	1950s	Galaxolide, Tonalide	Clean, sweet, laundry
Macrocyclic musks	1920s on, widely used later	Muscone, Exaltolide, ambrettolide	Warm, soft, skin-like

Nitro musks were an accident. In 1888 the German chemist Albert Baur was working on explosives related to TNT and found that one of his compounds smelled strongly of musk. Nitro musks carried perfumery for half a century, but they turned out to have safety problems. IFRA, the industry’s standards body, prohibits musk ambrette after it was found to cause skin reactions in sunlight, and the EU now requires authorisation to use musk xylene.

Polycyclic musks replaced them, and Galaxolide is the famous one. IFF describes it as a clean, persistent musk. It’s cheap and stable, which is why it’s in detergent and fabric conditioner, and why so many people think musk smells like clean washing. In a sense it does: that smell is musk.

Macrocyclic musks are the ones closest to the deer. Leopold Ružička worked out in 1926 that muscone, the main odour molecule of deer musk, is a ring of 15 carbon atoms, and the work fed into his share of the 1939 Nobel Prize in Chemistry. These large rings were hard to make cheaply for decades. Today they’re the soft, skin-like musks behind most “your skin but better” perfumes. dsm-firmenich describes Exaltolide as musky with a faint fruitiness, and its Muscone Laevo as the animalic, Tonkin-musk character of the original.

There’s also a plant musk. Ambrette seed, from a relative of hibiscus, contains ambrettolide, a macrocyclic musk with a pear-like edge. It shouldn’t be confused with musk ambrette, the banned nitro musk, despite the name.

Why Can’t Some People Smell Musk?

Because musk molecules are large, and noses differ in which large molecules they can detect. Many people have a specific anosmia to one or more musks: their sense of smell is fine, but that particular molecule is invisible to them. That’s why one person finds a musk perfume lovely and the friend next to them smells almost nothing.

Perfumers know this, and many formulas use several musks at once so that most people can smell at least one of them. It’s also why “I can’t smell my perfume” is a more common complaint with musk scents than with anything else.

What Does Musk Do in a Perfume?

Two things. Musks are heavy molecules that evaporate slowly, so they’re still there when the citrus and flowers have gone, and they give a perfume a soft, rounded finish. They also make the other notes feel smoother and closer to the skin, which is why even perfumes that don’t list musk usually contain some.

What musk won’t do is act as a pheromone. Human attraction to musk is a matter of taste, and our attraction guide covers what the research actually found. What makes perfumes last has more on why heavy molecules stay longest.

Which Perfume Shows Off Musk?

Narciso Rodriguez built his name on it. For Her EDP puts a musc accord at the centre, with rose and peach around it and amber and patchouli below. The rose and peach are soft enough that the musk stays in charge, and it smells polished and close rather than clean or animal. It’s the pink bottle; the EDT is a different, lighter composition.
