Description of key information

Two biodegradation tests are available, one key study carried out according to the OECD guideline 301C and one supporting study carried according to the OECD guideline 301B. Both studies concluded that the substance is not readily biodegradable.


Additionally, a QSAR exercise was performed to identify relevant degradation products of the substance, using the EAWAG-BBD Pathway Prediction System model. 41 degradation products were identified, and these were then assessed for their P (B and T) properties in view of the PBT/vPvB assessment. The biodegradability of each of the degradation products was predicted using the QSAR model BIOWIN available in the EPI Suite software. Of the 41 degradation products, 14 were predicted to be not readily biodegradable. The remaining 27 degradation products were predicted to be readily biodegradable.
