Description of key information

Waived:  Readily biodegradable

Key value for chemical safety assessment

Additional information

In accordance with Column 2 of REACh Annex IX, the study need not be conducted if the substance is readiliy biodegradable. 2,6 -dimethylheptan-4 -one (diisobutyl ketone) was shown to be readily biodegradable, with 88% BOD observed after 20 days in the closed bottle test.
