Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Key value for chemical safety assessment
- Log Kow (Log Pow):
- -1.33
- at the temperature of:
- 20 °C
Additional information
A reliable QSAR method predicts a value for the partition co-efficient (logKow) of -1.33 for this substance.
According “ANNEX VII - STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF ONE TONNE OR MORE” AND the Adaptations of the standard physico-chemical testing requirements under REACH, the study for Partition coefficient n-octanol/water (Kow))does not need to be conducted if :
This data does not need to be determined if the substance is purely inorganic.
The test can not be technically performed if:
– the substance decomposes;
– the substance is a surface-active substance (as it interferes with partitioning);
– the substance reacts violently during the performance of the test;
– the substance does not sufficiently dissolve in water or in octanol;
– it is not possible to obtain a sufficiently pure substance.
This substance dissociate in aqueous solution.
Therefore testing for Partition coefficient n-octanol/water (Kow)) does not need to be performed.
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.
