Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The QSAR calculated rate constant for the OH sensitized photodegradation of isophorone diamine is approximately 8.47E-11 cm3/(molecule * s). At 500,000 OH radicals / cm3 (approximate 24-hour mean in central), this corresponds to a half-life of 4.5 hours. The hydrolysis of isophorone diamine as a function of pH was studied according to OECD TG 111. At pH 4,7 and 9, less than 10% of the test substance were observed to hydrolyse at 50 °C within a period of 5 days, demonstrating hydrolytical stability in the environment.
