PMD Testing

p- Menthane-3,8-diol (PMD) is a biochemical pesticide derived from eucalyptus plants. This active ingredient is used to make products that are applied to human skin and clothing for the purpose of repelling insects, such as mosquitoes. It can be used in two types of consumer pesticide products: a spray and a lotion.

PMD occurs naturally in the lemon eucalyptus plant. The natural oil can be extracted from the eucalyptus leaves and twigs. Its odour and chemical structure are similar to menthol and it has a cooling feel. Its repellent effect was discovered in the 1960s. There are eight possible stereoisomers of PMD; the exact composition is rarely specified and is commonly assumed to be a complex mixture.

Refined OLE contains approximately up to 70% PMD (a mixture of the cis and trans isomers of p-menthane-3,8-diol). OLE has been notified under the BPR Regulation (EU) No. 528/212) under its generic name “PMD rich botanic oil” and is currently proceeding through the registration process with the Health and Safety Executive in the UK.

How can we help with your testing requirements?

We have established methods for various types of products containing PMD. 

We can develop and validate methods to support your registration requirements on these complex natural products.

Helping you through the Biocidal Products Regulations to be able to market your product and providing stability and safety data through various physical and chemical testing.

These tests can all be done in compliance with GLP where required, and if the formal certification is not required you can still rest assured that all of our processes are carried out following the same high-quality standards even when outside of GLP.

We partner with consultants and other laboratories to support additional testing requirements too – so if we can’t do it, we will help you find someone who can through our trusted network.

Please contact us for further discussion of your particular PMD testing requirements.
