Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The environmental stability of Choline hydroxide is not assessed experimentally. Concerning phototransformation in different compartments (i.e. air, soil and water) no information is available and represents no mandatory requirement for a registration under REACH.
The reliable read-across substance Choline chloride (CAS 67-48-1) was found to be readily biodegradable (BASF AG, 1984), which can be also presumed for the target substance Choline hydroxide. For further information and the detailed description of the read-across procedure, please refer to the separate read-across statement by Chemservice S.A. (2013). Based on the biodegradability, no experimental investigation concerning hydrolysis is triggered and this endpoint can be waived in accordance to REACH, Annex VIII, Section 9.2.2.1, column 2.
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.
