Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Additional information
The biodegradability of the test item was tested according to OECD Guideline 301F with non-adapted activated sludge for a period of 28 days. The test substance was tested in a concentration of 28 mg/L, corresponding to a ThOD (theoretical oxygen demand) of 52.9 mg O2/L per test vessel. The oxygen was depleted by the respiration of bacteria and the degradation was followed by measuring the oxygen concentration. The biodegradation rate is therefore expressed as the percentage BOD (biological oxygen demand) and was calculated according to OECD 301 for each study day by using the following formula:
% biodegradation = BOD (mg O2/L) / ThOD or ThODNO3(mg O2/L) x 100
According to OECD 301 the pass level for ready biodegradability (60% ThOD to be reached within a 10-day window of the 28-d period) is fulfilled by the test substance in the tested concentration. Hence the substance is considered to be readily biodegradable. The validity criteria of the guideline are fulfilled.
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.
