Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with Column 2 of REACH, Annex VII the tests does not need to be conducted if the substance is inorganic. Thus no additional test is required for this endpoint. However, in order to use Chesar for environmental risk assessment and considering the ionic nature of this salt and its full miscibility in water, a theoretical log POW of -3 is used as replacement value.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -3
- at the temperature of:
- 20 °C
Additional information
The exposure scenario and risk assessment tool Chesar requires a logPOW value in order to work and cannot operate with a blank value for logPOW. Therefore, it was qualitatively assessed, based on the ionic nature of the substance and the very good water solubility that a value of 1000 as partitioning coefficient for water/octanol is appropriate and consequently the logPOW is estimated being -3.
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.
