What is a Flash Point, and why is it required? 


What does Flash Point mean?

The lowest temperature at which a liquid will form a vapor in the air near its surface that will “flash,” or briefly ignite, on exposure to an open flame. 



Why is it required for some products?

Because the Flash Point is a general indication of the flammability or combustibility of a liquid, it is critical data needed for registration.  

  • Below the Flash Point, insufficient vapor is available to support combustion. 
  • Above the Flash Point, the liquid will produce enough vapor to support combustion.


Where is the Flash Point located on the Safety Data Sheet (SDS)?

Section 9 of the Safety Data Sheet.

  • The Flash Point will be for the whole product; certain components may drive the Flash Point value of your overall product. 


Note: If a product contains oils and does not list a Flash Point on its Safety Data Sheet, it may delay the assessment team. They may inquire about the Flash Point, which you will then need to provide to them.



The most common ingredients that can contribute to a product having a Flash Point:

  • Isododecane

  • Ethanol

  • Methanol

  • Isopropanol

  • Acetone

  • Ethyl Acetate

  • N-Butyl alcohol



Where to upload a Flash Point test

If a product is suspended and you are asked to provide Flash Point testing, you will want to obtain a closed-cup testing method. 

  • The test results should be uploaded to the 'Review and Submit' section of the registration under 'Additional Documents to Provide'.
