Description of key information

The QSAR calculated partition coefficient 1-octanol/water of Isophorone diisocyanate cyclodimer (uretdione type), which is the main constituent of the title substance, is reported as 9.73. 

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
25 °C

Additional information

Since rapid hydrolysis is expected in the environment, this value is not relevant. It also does not represent the complete substance but only one constituent. The higher oligomers are expected to have even higher log Kow values.
