Description of key information
Additional information
According to a Mackay Level I model calculation the main target compartments for isophorone diisocyanate cyclodimer will be sediment and soil (50 % each). Similar behaviour is expected for the higher oligomers. The calculated Henry’s law constant of 0.63 Pa m3/mol indicates low volatility of isophorone diisocyanate cyclodimer from surface waters. Similar behaviour is expected for the higher oligomers. However, due to rapid hydrolysis no equilibrium partitioning in the environment can be established. 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). Even higher values are expected for the higher oligomers. However, they are all not relevant because of the rapidy hydrolysis of all the oligomers.
