Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

MIBK is a very soluble substance (14.1 g/L) with a low log Kow (1.9). MIBK is therefore not expected to sorb on sediment/soil particles. Moreover as demonstrated in the frame of a biodegradation test, MIBK is readily biodegradable. MIBK is also a solvent with a vapor pressure of 2.64 kPa at 25ºC. MIBK is therefore volatile. Based on those mentioned intrinsic properties MIBK is not expected to persist in terrestrial compartment. The foreseen ecotoxicity for sediment/soil organisms is expected to be negligible due to low exposure level considerations.
