Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The most important and widely accepted indication of bioaccumulation potential is a high value of the partition coefficient, Log Pow, and it is accepted that values of Log Pow in excess of 3 indicate that the substance may bioaccumulate. MK92K displayed a range of Log Pow values from <0.24 to 3.93, with a significant proportion of the components having Log Pow values < 3. As the major proportion of the components have a Log Pow <3, the potential for bioaccumulation of MK92K in aquatic organisms is likely to be minimal.

Key value for chemical safety assessment
