Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Photo-transformation of the category substances in water is not an important process affecting fate of the MDI category substances in the environment. It can be assured that this is a negligible removal mechanism, as the rate of hydrolysis would predominate over the rate of any photolytic degradation as exposure to sunlight in surface waters would also involve exposure to water. The lack of experimental or predicted photo-transformation in water data is not considered as being a deficit for the assessment of potential environmental exposures to the MDI substances.

Key value for chemical safety assessment
