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. 

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

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

These tests can all be done in compliance with GLP where required. However 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.

Our services include:

New regulations around Biocides came into place in 2012 . We have since therefore worked with industry to support registration needs conducting 5 batch analysis, routine testing, storage stability, physical testing and more on a wide range of Biocides.

Biostimulants are a wonderful new way to protect our plants and wildlife by using nature to protect itself. They are natural substances harnessed for their characteristics. After that they are developed into products that can be applied to seeds, plants and soils in order to stimulate natural growth. 

We have worked with consultants and direct customers for many years supporting their Agrochemical registration testing requirements under global regulations. Find out more here

We can design storage stability studies with or without GLP accreditation under the Biocides, Plant Protection, or ICH guidelines to support registration around the world. Find out more here

Need data for registration or a safety data sheet?

From explosive properties through to partition co-efficient, we cover a wider range of physical tests and can also develop our own in-house methods for novel experiments.

We use a range of methods from CIPAC, ASTM, ISO, OPPTS, OECD and more to meet global regulatory requirements. Find out more here

We can cover elemental to extremely low levels. For instance if you just need to identify, quantify, or fully validate a method. Our ICP systems cover a wide range of elements often working on 10+ elements at the same time. 

We regularly work on Silver, Lead, Arsenic, Chromium, Cadmium, Mercury, Copper, Boron and Sodium to name a few. Our list of capabilities stretches much longer! Find out more here

We can carry out impurity profiling, product screening, method validation and 5 batch analysis or Technical Equivalence studies to meet your registration needs. Our team develop tailored methods for your products and can also support with structural identification requirements.

We have many years of experience with successful studies over many compounds from Citric Acid to Pyrethrins covering elemental impurities, isomers, and additives of all types. 

Whether your product is a TC, or TK we can help. Find out more here

We have been developing tailored methods at affordable prices for many years. Our chemists have developed thousands of methods over the years from simple single actives to complex products covering a wide range of levels and product types. 

We can also validate already developed methods or support you through your own method development journey via consultation.

Our validation expertise covers global requirements including SANCO/3030/99, SANTE/2020/12830 and ICH Q2, OPPTS 830.1800 and APVMA among others. Find out more here

The fertiliser market is well established but under scrutiny with the introduction of new regulations demanding more rigorous testing and reducing acceptable levels of elements. 

We are one of few labs that can offer the full suite of Fertiliser testing including Inorganic Arsenic, and Chromium VI. Find out more here

Need routine quality checks, one offs or concerned about contamination?

New regulations to meet? We often take on complex novel projects and it is what we are known for! Our chemists enjoy doing something different! Find out more here
