Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
LogPow = -0.713 for methylamine in aqueous solution
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -0.713
- at the temperature of:
- 25 °C
Additional information
Given that the substance is in solution in water, it is expected to present the same range in the partition coefficient as its organic component: methylammonium. The logPow reported for methylamine in aqueous solution is negative, so the logPow of MMAN is also expected to be negative. This implies that MMAN has a very low Kow (lower than 10), indicating a great hydrosolubility potential. This is coherent with the state in aqueous solution. Therefore, the partition coefficient octanol/water does not need to be further assessed.
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.
