Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The ready biodegradability was evaluated in a study performed in accordance with OECD testing guideline 301 D and GLP requirements.
The maximum level of biodegradation was 0 % in 28 days. Therefore, according to these results, the test substance is not considered as readily biodegradable.
In the test conditions, no inhibitory effect on the micro-organisms of the inoculum was observed. Validity criteria were fulfilled.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The ready biodegradability was evaluated in a study performed in accordance with OECD testing guideline 301 D and GLP requirements.
The test substance is not biodegraded in the closed bottle test, and therefore should not be classified as readily biodegradable. This lack of biodegradation is not due to toxicity of the test compound because the endogenous respiration is not inhibited. Lack of biodegradation does not mean that the test substance is recalcitrant in nature. The stringency of the test procedures could account for the recalcitrance of the test substance in the closed bottle test.
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.
