Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- No biodegradation has been observed under the test conditions (0% degradation after 20 days). The reliability of the test cannot be assessed as the documentation is insufficient (reliability 4 assigned).
- Executive summary:
A test in closed bottles was performed to assess the ready biodegradability of the test item (duration 20 days). No biodegradation has been observed under the test conditions (0% degradation after 20 days). As the documentation is insufficient to assess the reliability of the test, QSAR estimation has been done in addition, which confirmed the result "not readily biodegradable".
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
