Additional information

The bioaccumulation potential of tert-Butylperoxy-3,5,5-trimethylhexanoat was estimated with an experimentally determined log Kow of 4.4. The bioaccumulation factor (BCF) was calculated to be 372 L/kg using the EPA Epiwin (v.4.0) software. Furthermore, direct and indirect exposure of the test item to water and soil is highly unlikely, due to the unstable nature of organic peroxides. Therefore, the test item is considered to be of no concern regarding bioaccumulation.
