- Sampling time:
- 28 d
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- The average percentage biodegradation of the test item by BOD was 75% after 28 days. In addition, the percentage biodegradation of the test item by BOD at the end of the 10-day window exceeded 60% (73% and 77%). These results met the pass level of readily biodegradability in OECD Guidelines for Testing of Chemicals. Therefore, it showed that the test item is a readily biodegradable substance.
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.
