Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test substance is inherently biodegradable, not fulfilling specific criteria, as shown in Zahn-Wellens tests (OECD302B). The test substance was also shown to be rapidly biodegradable in an enhanced ready biodegradability test, but the fact that the test was enhanced does not allow drawing conclusions on ready biodegradability. The first step in degrading the test substance is demethylation, which is the slow step, followed by faster degradation of morpholine through ring cleavage. Adaptation of the sludge was shown to substantially speed up the degradation. Further findings indicated that slowly reproducing organisms in sludge are the organisms most efficiently breaking down the test substance. Therefore, WWTPs including a step with low load and high sludge age (>= 14 days) would be more efficient in rapidly removing the test substance.
Additional information
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.
