Synthesis route :

Eucalyptol is a little synthesized raw material, as it can be extracted from Eucalyptus EO and other oils with a high yield and high purity.

Synthesis precursor :

Eucalyptol can be a precursor to the synthesis of other terpenes, by a Diels-Alder reaction for example.

Isomerism :

Eucalyptol has several constitutional isomers, mainly with a floral note: Linalool, Geraniol and Nerol are part of it. Menthone® is also an isomer of Eucalyptol, and has a very minty note, but less coniferous.

Natural availability :

Eucalyptus EO contains up to 85% Eucalyptol, therefore the molecule can be extracted with a purity of up to 99,8%. Bay Leaf EO also contains up to 70% Eucalyptol.

Allergens :

This ingredient does not contain any allergen.
