p-Menthane-3,8-diol, also known as para-menthane-3,8-diol and PMD, is an active ingredient used in insect repellents. It smells similar to menthol and acts as a coolant. PMD is found in the oil within leaves of the Eucalyptus citriodora tree. This tree is native to Australia, but is now cultivated in many warm places around the world. This oil, when refined for use in insect repellents, is known as Oil of Lemon Eucalyptus or, more commonly, Citriodiol. Typically, Citriodiol contains 64% PMD (a mixture of the cis and trans isomers of p-menthane-3,8-diol). Citriodiol has been notified under the European Biocidal Products Directive (BPD) 98/8/EC and is currently proceeding through the registration process with the Heath and Safety Executive in the UK. It is the only natural ingredient that can now be used as an insect repellent.
