Description of key information

Additional information

Measured bioconcentration information is not available for HQEE, therefore a waiver is applied. 

In accordance with Column 2 of REACH annex IX, the bioaccumulation test on fish need not be conducted if the substance has a low potential for bioaccumulation (for instance a log Kow <3) and/or a low potential to cross biological membranes. The partition coefficient of HQEE was determined in a reliable study (Young 2012) where the measured Kow is 0.41. Therefore, HQEE is considered to have low potential for bioaccumulation and no further testing is required.
