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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
