Musk: Four Generations
Animalics and Musk · 7 min
No word in perfumery is used more loosely. Musk originally named one specific material and now names at least four unrelated chemical families with wildly different smells. Untangling them is one of the more useful things a serious enthusiast can do.
Generation one: the deer. Genuine musk is a glandular secretion of the male musk deer, native to the Himalayas and Siberia. Harvesting killed the animal. The tincture is warm, dusty, faintly faecal, sweetly animal and remarkably persistent, and it was among the most valuable substances in pre-modern trade. It has been effectively banned since the musk deer's CITES listing in 1979. Assume that no fragrance you can buy contains it.
Generation two: nitro-musks. Discovered accidentally in 1888 by Albert Baur while working on explosives, musk ketone and musk xylene were the first synthetic musks. They smell sweet, powdery and slightly nutty, and they defined the powdery softness of early twentieth-century perfumery. They were phased out from the 1980s onward over toxicity and environmental persistence concerns.
Generation three: polycyclic musks. Galaxolide, introduced in the 1960s, is the most widely produced fragrance material on earth. It is clean, sweet, soft, slightly fruity, and it is the smell of laundry detergent — genuinely, that association runs that way round, because it is used in vast quantities in fabric softener. It is also extremely persistent in the environment and turns up in water sampling worldwide. Tonalide is its close relative.
Generation four: macrocyclic musks. Large-ring molecules, some found in nature — ambrettolide occurs in ambrette seed, muscone is the deer's own musk molecule, now made synthetically. These are the expensive, elegant ones: Habanolide, Exaltolide, Velvione, Muscenone. They smell warmer, more skin-like, less soapy, and they biodegrade far better. Most high-quality contemporary musk work is here.
Two things follow. First, when someone says a fragrance is musky, ask which musk — clean-laundry Galaxolide and warm-skin muscone are barely the same word. Second, and stranger: musk anosmia is real and common. A significant minority of people cannot smell specific musk molecules at all, with estimates for some individual musks running above ten percent of the population. This is not a general failure of the nose; it is molecule-specific. If a fragrance everyone else calls enormous smells like almost nothing on you, you may simply be anosmic to its principal musk — and that is a genuine, measurable phenomenon rather than the vague 'skin chemistry' folklore examined later in this course.
Key terms
- Nitro-musk
- The first synthetic musk class, discovered in 1888, sweet and powdery, now largely withdrawn on safety grounds.
- Galaxolide
- A polycyclic musk from the 1960s, clean and soft, the most heavily produced fragrance material in the world.
- Anosmia (specific)
- Inability to smell one particular molecule while smelling everything else normally — common with musks.
