Rich, warm, powdery macrocyclic musk with a subtle fruity layered. Structurally a ketone like muscone, but creamier and with a faint ambergr is-like sweetness.

Scent

Rich, warm, intensely musky with a creamy powdery body. Warmer than Galaxolide, less clean than Habanolide, more animalic-sweet than either. A faint fruity lift separates it from the purely skin-like quality of muscone.

Evolution over time

Immediately

Rich musky burst with powdery-fruity top

After a few hours

Warm creamy musk, ambergris-like sweetness

After a few days

Persistent skin-close musk, extremely long-lasting

The Full Story

Cosmone (CAS 10461-98-0) is a macrocyclic musk ketone, specifically (5E)-3-methylcyclotetradec-5-en-1-one. It belongs to the same structural family as muscone and civetone rather than the lactone family of ambrettolide.

The scent is intense and diffusive: a rich, warm musk with powdery qualities and a faint fruity layered. It carries an ambergr is-like sweetness similar to of nitro musks but without their regulatory concerns. Effective at 0.1% concentrati on.

Cosmone functions as a base note and fixative. It provides musky radiance and sillage to virtually any composition.

Did You Know?

Did you know?

Macrocyclic musks like Cosmone contain 14-16 carbon atom rings, close to natural muscone (15 carbons). This size match explains why macrocyclics smell more natural than polycyclic musks like Galaxolide, which have completely different molecular architecture.
