Key value for chemical safety assessment

Additional information

The partition coefficient octanol/water of 2 -ethyl-4 -methylimidazole (CAS 931 -36 -2) was determined experimentally to be log Kow 1.13 (BASF AG, 1989; Report no. 104547/02). In accordance with column 2 of REACH Annex IX, the study need not be conducted since the substance has a log Kow less or equal than 3.

Based on these results it can be concluded that accumulation in organisms is not to be expected.
