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.

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 40 mg/L and 100 mg/L, corresponding to a ThOD (theoretical oxygen demand) of 53.4 mg O2/L and 133.4 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 not fulfilled by the test substance in the tested concentrations. Hence the substance is considered to be not readily biodegradable. The validity criteria of the guideline are fulfilled.
