Ethylene Brassylate

aka 1,4-dioxacycloheptadecane-5,17-dione · ethylene brassylate macrocyclic musk

A synthetic macrocyclic musk used as a fragrance fixative. Different safety profile from nitro-musks and polycyclic musks — one of the cleaner fragrance fixative alternatives used in transparent or reformulated fragrance compositions.

Benefits
  • Clean musk — sweet, musky, white fragrance character
  • Fixative — anchors volatile top notes
  • Biodegradable relative to nitro-musks
  • Preferred alternative to restricted musks (nitro-musks, HHCB in some applications)
  • Low sensitisation potential versus older synthetic musks
Example uses
  • Skin-scented serums
  • Body lotions with fragrance
  • Fine fragrance compositions
  • Haircare fragrance bases
  • Eau de toilette base notes
Formulation notes

Oil-soluble fragrance component. Stable in cosmetic matrices. Not subject to same IFRA restrictions as nitro-musks or some polycyclic musks.

Watchouts

Synthetic origin — flagged in strict natural fragrance frameworks. Some bioaccumulation concerns raised in aquatic environment literature (lower than polycyclic musks but not absent). EU is reviewing macrocyclic musks as a class.

Clean beauty perception

Better received in clean-beauty fragrance reformulation than polycyclic or nitro-musks. Positioned as a safer synthetic musk alternative within the reformulated fragrance discourse.
