Citriodiol®  is our registered trade name for the active Eucalyptus citriodora oil, hydrated, cyclized (EC Oil (H/C)), also known as “Oil of Lemon Eucalyptus” (OLE).


Approved by leading regulatory authorities around the world, Citriodiol® is as effective as synthetic actives such as DEET and far superior to other natural alternatives. Citriodiol® typically contains about 71% p-methane-3,8-diol (PMD), and is synergistically enhanced by the remaining naturally occurring plant oil constituents not contained in synthetic PMD, increasing its overall repellency.

Citriodiol® is a naturally sourced active ingredient found in many insect repellents worldwide. This plant based active substance is sustainably and ethically sourced and has first-rate efficacy comparable to synthetic active substances, such as DEET.

Citriodiol® is produced from the distilled oil of Eucalyptus citriodora trees (also known as Corymbia citriodora) using an accelerated process that mimics what naturally occurs in the leaf, by converting the citronellal content into p-menthane-3,8-diol (PMD).

Unlike other essential oil based products, Citriodiol® has passed the most rigorous safety and efficacy tests. It has met the highest standards, obtaining registrations from some of the world’s leading authorities.
