Description of key information

According to structural properties, hydrolysis is not expected/probable. 

Key value for chemical safety assessment

Additional information

According to Kollig et al. (1993), Boethling & Mackay (2000) and Harris (1990), the substance is generally resistant to hydrolysis because it does not contain any labile functional groups.

Due to the chemical structure of 4,4'-methylenebis(2-methylcyclohexanamine) (CAS 6864 -37 -5, DMDC) hydrolysis is not likely to occur under environmental conditions based on a lack of funtional groups which may hydrolyse (SIDS Initial Assessment Report For SIAM 13). Therefore, it is concluded that hydrolysis is not an important process in the fate of DMDC.
