Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The QSAR calculated rate constant for the OH sensitized photodegradation of isophorone diisocyanate cyclotrimer is approximately 4.02E-11 cm3/(molecule * s). At 500,000 OH radicals / cm3 (approximate 24-hour mean in central Europe), this corresponds to a half-life of 9.6 hours. Higher oligomers have more reactive functions and therefore a lower half-life will be calculated.
The tests on hydrolysis indicate a rapid decomposition of the test substance in water (half-life < 12 hours at 20 -25 °C and relevant pH values).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
