Description of key information

With a calculated Koc of 2,233,000 l/kg, the sorption potential of isophorone diisocyanate cyclodimer to soil or sediment organic matter is expected to be very high (Blume scale).

Key value for chemical safety assessment

Koc at 20 °C:
2 233 000

Additional information

Even higher values are expected for the higher oligomers. However, they are all not relevant because of the rapidy hydrolysis of all the oligomers.
