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

Ready biodegradability:

The test item was investigated for its ready biodegradability in a manometric respirometry test according to the OECD Guideline for Testing of Chemicals, No. 301F and EU-Method C.4-D. The test was performed in closed vessels containing a known concentration of test item (100 mg test item/L giving 82 mg Theoretical Oxygen Demand/L) incubated at constant temperature (23 °C) for 28 days. The Biochemical Oxygen Demand (BOD) of the test item in the test media significantly increased from the test start until approximately day 7 of incubation, where biodegradation reached a mean value of 27 % (average of two replicates). Afterwards the biodegradation values remained in a plateau phase, with mean values in the range of 27 % to 31 %, until the end of the test, on day 28, when the mean biodegradation value amounted to 30 %. At the end of the 10-day window, the mean biodegradation of the test item reached approximately 28 %. Therefore, the pass level for ready biodegradability, i.e. biodegradation of at least 60 % of the ThOD in a 10-day window within a 28-day period of the test, was not reached. In conclusion the test item was considered as not readily biodegradable under the test conditions within 28 days.
