Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In water, potassium methanolate rapidly hydrolyses to methanol and potassium hydroxide (OECD, 2002). Potassium hydroxide further dissociates in the environment to potassium and hydroxyl ions. Both ions do not have the potential for adsorption on particulate matter or surfaces (OECD, 2002). For methanol, measured and calculated Koc values < 1 demonstrate a low adsorption potential (Lokke, 1984; Howard, 1990).
Gaffney et al. (1987) published a Henry’s law constant of 0.461 Pa m³/mole for methanol. Hence, potassium methanolate and its degradation product methanol are not expected to significantly volatilise from surface water and volatilisation is not a significant removal process from the aquatic compartment. Potassium hydroxide dissociates in water and is also expected to remain in the aquatic compartment.
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.
