Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No sediment toxicity data were available for freshwater or marine sediments exposed to diisobutyl ketone (2,6-dimethylheptan-4-one, DIBK).

Key value for chemical safety assessment

Additional information

Direct or indirect exposure of the sediment compartment is unlikely because Diisobutyl ketone has a low potential for adsorbtion to sediment, having a Log Koc of 2.07. It is also readily biodegradable and has moderate water solubility (430 mg/l). The risk assessment shows that the estimated PEC/PNEC ratios are clearly <1, indicating no further information or testing is needed.
