DEET Testing

Oxford Analytical are a GLP approved facility for all your DEET testing requirements.

Diethyltoluamide (DEET) is the common active ingredient in many insect repellent products. It is widely used to repel biting pests such as mosquitoes and ticks. Every year, DEET formulations are used to protect populations from mosquito-borne illnesses like West Nile Virus, the Zika virus, malaria, and/or tick-borne illnesses like Lyme disease and Rocky Mountain spotted fever. And, despite concerns over excessive exposure to the chemical, appropriate usage of the chemical at the recommended dosages and routes of administration have generally proven to be safe.

DEET was developed by the U.S. Army in 1946 and was registered for use by the general public in 1957. It is now widely used, with approximately 30% of the U.S. population using DEET repellents each year. 

DEET products are currently available in a variety of forms: liquids, lotions, sprays, and even impregnated materials, such as wristbands. Formulations registered for direct application to human skin contain from 4% to 100% DEET. Approximately 230 products containing DEET are currently registered with the U.S. Environmental Protection Agency (EPA).

How can we help with your testing requirements?

We have established methods using High Performance Liquid Chromatography (HPLC) for various types of DEET containing products – such as pump sprays, aerosols and even roll-on sticks.

Whether DEET is a single active or part of something more complex we can develop and validate methods to support your registration requirements.

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.
