Safety Profile
USE WITH AWARENESSWhat Does Eucalyptus globulus absolute Smell Like?
The absolute bursts with an intense camphoraceous punch – like menthol’s sharper cousin – followed by piercing cineolic freshness that conjures hospital corridors. Beneath the medicinal blast lies a subtle woody-green undertone reminiscent of crushed leaves after rain. As it dries, the harshness mellows into a clean, slightly sweet herbal character that lingers with a cooling sensation.

Chemistry, Properties & Perfumer Guide
The Chemistry
Eucalyptus globulus absolute contains 1,8-cineole (eucalyptol) as its dominant constituent (70-85%), along with α-pinene, limonene, and globulol. The extraction process typically involves solvent extraction of dried leaves followed by ethanol washing to remove waxes. Unlike steam-distilled eucalyptus oil, the absolute retains more of the heavier sesquiterpenes that modify the harshness of the cineole.
