Chemical Information
FooDB Namep-Menthane-3,8-diol
DescriptionConstituent of the roots of Litsea cubeba (mountain pepper) 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.

Classification
Description belongs to the class of organic compounds known as menthane monoterpenoids. These are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes.
