Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Biodegradation in water: Screening tests: not readily biodegradable, 4% in 28 days (O2 consumption) (EU Method C.4-D / OECD 301 F (Ready Biodegradability: Manometric Respirometry Test))
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
There is an OECD guideline study on biodegradation in water: screening tests available, assessed with Klimisch 1 and hence considered as sufficiently reliable to cover this endpoint.
3-cyclohexylaminopropane-1-sulphonic acid was tested for the ready biological degradability in a Manometric Respirometry Test according to EU Method C.4-D / OECD 301 F. Within 28 days a degradation of 4 % based on O2 consumption was attained, a 10-day-window was not observed. As degradation missed 60 % after 28 days, the test item has to be considered as "not readily biodegradable".
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.
