Description of key information

Based on the information from inherent biodegradation testing (56 d degradation: 4.4 %) according to the modified test method based on OECD guideline 310 and on very low water solubility (<3.75 µg/l) and consequently unlikely hydrolysis in the environment it has to be assumed that the test substance is persistent in the environment as no biotic degradation was observed.  Further biodegradation testing will probably come to the same results. As the chemical safety assessment does not indicate a hazard for the environment, further simulation tests are neither necessary nor helpful.
