CAS 1222-05-5 · Musk · Polycyclic · Not restricted by IFRA
Galaxolide is IFF's HHCB, the clean, sweet polycyclic musk behind the 'fresh laundry' smell of countless detergents and a quiet workhorse in fine fragrance. It adds volume, softness and staying power without drawing attention to itself.
What it smells like
Clean and sweet with a soft floral-woody musk, like freshly washed cotton. Diffusive and very long-lasting, so you notice it more in the dry-down than on the first sniff.
How perfumers use it
Use it as a base note and fixative in florals, fresh and woody accords, and in attar-style oils. Layering it with a macrocyclic musk such as Habanolide or ethylene brassylate gives a rounder, more expensive-smelling musk base than any single musk.
Blends well with: Habanolide, Musk T / Ethylene Brassylate, Iso E Super, Hedione, Ambroxan.
