Description of key information

The partition coefficient for 2,6-dimethylheptan-4-one (diisobutyl ketone) is determined by the HPLC method to be 3.71.

Key value for chemical safety assessment

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

Additional information

The Log Pow value for DIBK was estimated based on its chromatographic retention time in a standard HPLC assay following the OECD 117 guideline. The test substance eluted as a single chromatographic peak, having a retention time of 4.93 minutes, which correlated to an estimated log Pow of 3.71.
