What it is
Eucalyptus Globulus Oil is the essential oil obtained by steam distillation of the leaves of Eucalyptus globulus, with 1,8-cineole (eucalyptol) typically its dominant constituent. In cosmetics it contributes a characteristic fresh, camphoraceous aroma and a perceived cooling effect, which is why it appears in products marketed with a cool or minty feel. It is used at low levels as a fragrance and sensory ingredient rather than for any functional skin benefit.
Safety & warnings
Eucalyptus oil is a volatile aromatic material that can irritate skin and mucous membranes and may cause contact sensitization in some people; its high cineole content is a known concern for irritation. It should be used at low concentrations, and individuals with sensitive or reactive skin or known fragrance allergies may wish to avoid it. Undiluted eucalyptus oil is irritating and is not intended for direct application.
Origin & sourcing
Natural; a steam-distilled essential oil from the leaves of Eucalyptus globulus, a tree native to Australia.
