Description of key information

After evaporation or exposure to the air, the product will be rapidly degraded by indirect photochemical processes 

Key value for chemical safety assessment

Additional information

Based on the calculation according to AOPWIN v1.92 (EPI Suite v4.11), 2,2'-dimethyl-4,4'-methylenebis(cyclohexylamine) (DMD) is indirectly photodegraded by reaction with hydroxyl radicals in the atmosphere with a half-life (DT50) of about 3.2 hours taking into account a 24-h day and a mean OH radical concentration of 500000 radicals per cm³. The overall OH rate constant was 119.9076 E-12 cm³/molecule*sec (BASF SE, 2015).
