Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a ready biodegradability study, the test material was shown not to meet the criteria to be considered as readily biodegradable. The percentage degradation observed at 28 days, was comparable to that of the abiotic control, 42.8% and 47.2%, respectively. Thus, the observed reduction of DOC from the test vessel cannot be attributed to the microbial inoculum and is considered to be a result of hydrolytic instability. The test material did not have an inhibitory effect on the inoculums, shown by the toxicity control, 38.7% degradation was achieved by Day 4. The reference substance was determined to be readily biodegradable, indicating the acceptability of the inoculum activity and validity of the test procedure.
No further biodegradation tests were conducted. Direct and indirect exposure of surface water and sediment was considered unlikely, as was exposure to the soil compartment.
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.
