Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 performance of tests for biodegradation in soil is scientifically unjustified.
REACH Regulation No. 1907/2006, Annex IX, Sect. 9.2.1.3, Col. 2, states as follows:
“9.2.1.3: The study need not to be conducted:
- if the substance is readily biodegradable, or
- if direct and indirect exposure of soil is unlikely. ”
Direct and indirect exposure of the test item to soil is unlikely. In addition, the substance is hydrolytically instable forming morpholine and sulphamic acid. Morpholine is readily biodegradable. Sulphamic acid is an anorganic compound which is not further biodegraded. Thus, further test on biodegradation are scientifically not justified.
Therefore simulation testing for biodegradation in sediment was considered not scientifically justified.
Key value for chemical safety assessment
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.
