Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Estimation based on solubility ratio:

log Pow= <-4.5 at 23°C and at pH 10.2

Key value for chemical safety assessment

Additional information

The partition coefficient n-octanol/water (log Pow) can not be determined according to OECD Guideline 107 (shake flask method) as the test item is not a pure substance. The determination of log Pow corresponding to OECD Guideline 117 (HPLC method) is also not applicable, as the test item is a salt and cannot be chromatographed under the prescribed conditions.

Due to this, the log Pow can only be estimated from the single solubilities in n-octanol and in water.
