Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Log Pow 0.324-4.63 at 35 degrees Centigrade and pH 6.9 (EU Method A.8)

Key value for chemical safety assessment

Additional information

The partition coefficient for the test item was measured following EU method A8 (O'Connor and Woolley 2010).

In addition, representative structures of the substance were assessed using the US EPA KOWWIN model (v.1.68) for the purpose of PBT assessment. Predicted log Kow values for the substance constituents range from -0.24 to 4.76. The only constituents with predicted log Kow values above the screening criterion for being potentially bioaccumulative are constituents in the group C9 alkanes and alkenes. In addition, experimental values were found for some of the constituents within the model dataset. Of the experimental values, only the value for nonane was above the screening criterion (log Kow: 5.65).
