Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance is considered as not ready biodegradable under the test conditions.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The substance Cyclohexanaminium, N,N,N-trimethyl-, sulfate (2:1) was not tested for the endpoint biodegradation in water. To cover the endpoint data from the structural analogue substance Cyclohexanaminium, N,N,N-trimethyl-, hydroxide (1:1) was used.
The conclusion that Trimethylcyclohexylammonium hydroxid, aqueous solution 50 wt.% was not readily biodegradable in this DOC Die Away test based on the determination of the decrease of the DOC content of test substance in the test assays. The DOC values at the respective sampling days were compared to the DOC values determined on day 0 at begin of exposure. The required pass level for ready biodegradability within a ten days window was not reached. At the end of exposure after 28 days the degree of biodegradation was <10 % expressed as removal of DOC.
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.
