2022, Mosquito repellent — Performance test guidelines — Part 1: Skin applie d, First 
Edition (26 page(s), in English)  
6. Description of content:  This Draft East African standard provides guidelines for the 
design and execution of studies to evaluate the performance of mosquito repellents 
formulated and prepared for application di rectly to human skin. These guidelines apply to 
products in any formulation intended to be applied directly to human skin.  
The purpose of these guidelines is to provide specific and standardized procedures and 
criteria for efficacy testing and evaluation of mosquito repellents for human skin. Their 
aim is to harmonize the testing procedures carried out in different laboratories and 
institutions in order to generate comparable data for registering and labelling such 
products by the national regul atory authorities. However, the requirements for 
registration of pesticides, including repellents, are determined by the national regulatory 
authorities.  
The guidelines provide guidance and procedures on laboratory studies, field trials and 
evaluation of t echnical material used in mosquito repellent products and on the methods 
used to determine their application rate(s) and effectiveness. Guidance is also provided 
on the single -dose evaluation of formulated repellent products. With some modification, G/TBT/N/BDI/304, G/TBT/N/KEN/1346, G/TBT/N/RWA/745, G/TBT/N/TZA/868,

  the gu idelines can be used to determine the repellency of candidate compounds for other 
flying insects that blood -feed on humans.  
Detailed treatment and analysis of repellent safety and toxicity data are beyond the scope 
of these guidelines, and it is assumed th at preliminary human safety assessments have 
been undertaken before the material(s) are applied to human skin. Any side -effects 
and/or undesirable characteristics experienced in association with the application and use 
of repellents in laboratory studies a nd field trials should be recorded and reported. The 
protocol must include provision for medical care and the reporting of adverse events.  
Products submitted for laboratory studies and/or field trials should be accompanied by 
the Material Safety Data Sheet , the labelling recommendation and the manufacturer's 
certification that the product is within the company's manufacturing specifications for that 
product. Independent physical and chemical assessment may be required before initiating 
the efficacy studies.  
Biological tests are subject to the variation that accompanies living organisms. Studies 
should therefore be conducted under the close supervision of personnel familiar with 
biological testing of repellents and with sound scientific and experimental proce dures; the 
principles of good laboratory practice or other suitable quality schemes such as the 
International Organization for Standardization should be applied.
