Description of key information

Additional information

The substance is characterised by estimated bioconcentration factors between 1.1 and 25920 covering BCF values of the parent compounds (isocyanate groups) and possible hydrolysis products (amine groups), respectively (Currenta, 2010d). Due to the chemical nature of the parent compounds (isocyanate groups) only the corresponding amines and further transformation products, resulting from the reaction of isocyantes with amines, will be found in the aqueous phase having BCF values between 1.1 and 3.2.
