Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No significant increase of the biochemical oxygen demand (BOD) was measured for the substance in the test media. The values for the BOD were in the normal range found for the inoculum controls. Consequently, the substance was not biodegradable under the conditions of the test within 28 days.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The test item was investigated for its ready biodegradability in a manometric respirometry test over 28 days according to EU Commission Directive 92/69 EEC, C.4-D (1992) and OECD Guideline for testing of Chemicals No. 301 F (1992).
The percent biodegradation of the test item was calculated based on the chemical oxygen demand (COD) of 1.14 mg 02/mg test item.
No significant increase of the biochemical oxygen demand (BOD) was measured for the substance in the test media. The values for the BOD were in the normal range found for the inoculum controls. Consequently, the substance was not biodegradable under the conditions of the test within 28 days.
No degradation of the test item occurred in the abiotic control under the conditions of the test.
In the toxic control no inhibitory effect on the biodegradation of the reference item was determined. Thus, the test item had no inhibitory effect on the activity of activated sludge microorganisms at the tested concentration of 100 mg/L.
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.
