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

The inherent biodegradability of the test item was determined in the Modified MITI Test (II) with non adapted activated sludge for a period of 28 days. The study was conducted according to OECD Guideline 302 C and compliant to GLP. The test item concentration selected as appropriate was 40 mg/L, corresponding to a ThOD of 54 mgO2/L. The oxygen was depleted by respiration of bacteria and the degradation was followed by measuring the oxygen concentration. The biodegradation is therefore expressed as the percentage BOD depletion and was calculated for each study day

Two test item replicates did not reach the 10 % level (beginning of biodegradation) within the test duration of 28 days. The 3rd test item replicate reached the 10 % level after 16 days. The pass level > 70 % for evidence of inherent, ultimate biodegradability was not reached within 28 days. After 28 days the mean biodegradation rate was 5 %.
