Citriodiol® is nature's most effective insect repellent. It is a naturally sourced active ingredient that is effective against a range of biting insects, nuisance insects and ticks. It is derived from the oil of the Eucalyptus citriodora tree (also known as Corymbia citriodora), which is a natural and renewable resource grown in several parts of the world.
Citriodiol® is produced from steam distilled Eucalyptus citriodora oil using a process that mimics and accelerates the ageing process which naturally occurs in the leaf, by converting the citronellal content into p-menthane-3,8-diol (PMD). PMD itself is usually only present at very low levels in natural essential oils, rarely more than 1% or 2 %. This conversion process to increase the PMD content makes Citriodiol® a far more powerful repellent than the natural essential oil itself.
PMD has long been known as the active compound responsible for the repellent effect, and it is the high levels of PMD in Citriodiol® which provide its efficacy. Citriodiol® contains a minimum of 64% PMD (a mixture of the cis and trans isomers of p-menthane-3,8-diol) together with a number of minor constituents found in essential oil which enhance the efficacy further.
Citriodiol® has been notified under the European Biocidal Products Directive (BPD) 98/8/EC and is in the final stages of evaluation under the European Union’s Biocidal Products Regulation (BPR).
Unlike other essential oil based products, Citriodiol® has passed the most rigorous safety and efficacy tests. For example, it has been reviewed and met the highest standards obtaining registration and end-use product approval from the following agencies
