A guaiazulene-family partially saturated sesquiterpene used for woody-amber notes. Specialty fragrance material with thin public data.
Didehydro-octahydro-7-isopropyl-1,4-dimethylazulene (CAS 68907-19-7) is a partially hydrogenated derivative of the guaiazulene skeleton used as a perfumery ingredient for woody, earthy, amber notes. Sesquiterpene-derived materials of this class can autoxidize on air exposure to form hydroperoxide and epoxide species that are more reactive than the parent compound. Public SCCS/CIR cosmetic safety monographs are limited; RIFM/IFRA cover industry use. Default-yellow (72) reflects acceptable structural chemistry tempered by data sparsity and class-level oxidation considerations.
