Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The partition coefficient is determined to 3.15 at 20 °C.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

A study according to OECD TG 117 HPLC method was conducted (BASF AG 1994a, 94L00087) to determine the log Pow value. Using the HPLC method the log Pow was determined to be 2.9 at 22 °C. Furthermore a study was conducted according to OECD TG 107 shake flask method (BASF AG 1994b, 94L00087) to verify the result of the HPLC. Using 6 replicates the log Pow was determined to be 3.15 at 20 °C. In general the results from the shake flask method will be regarded as more reliable. The log Pow of 3.15 was regarded as worst case assumption and thus was chosen as key

value for chemical safety assessment. The result is supported by a calculation using SPARC creating a value of 2.82 based on a scientifically calculation model.
