Organoleptic Properties

Odor Type: Musk
musk, ambrette, fruity, berry
Odor strength medium
Substantivity 400 hour(s) at 100.00 %
General comment At 100.00 %. musk ambrette fruity berry
This alicyclic topnote musk is easily perceived by all users. It has a PCM-like character with berry topnotes and ambrette like nuances. It can be used as a PCM replacer and is stable in most applications. Resembles the closest musk to Galaxolide ® in character. Very delicate musky note, less fruity and less Ambrette than Helvetolide® with more tenacity and more volume on the dry down
Arcadi Boix Camps, writing in 2004, says of Romandolide: “This material is clean, heavy, long-lasting, and similar to Galaxolide in many respects – though it is less fruity and more camphoraceous. … Although more diffusive than macrocyclic and polycyclic musks, the material performs in a way quite similar to these musk chemicals. Romandolide is just now finding use in perfumes including Absolu de Rochas and Angel Schlesser for men.” Musk, sweet, fruity-berry, ambrette

Potential Uses

Applications
Odor purposes Ambrette oil replacer, Floral, Musk, Oriental, Sandalwood, Woody
