Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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

Key value for chemical safety assessment

Additional information

Due to the chemical structure of the analogous substance 2,2'-dimethyl-4,4'-methylene bis(cyclohexylamine) (DMD)and the substance of this dossier hydrolysis is not likely to occur under environmental conditions based on a lack of functional groups which may hydrolyse (SIDS Initial Assessment Report of DMD for SIAM 13, 2001). Therefore, it is concluded that hydrolysis is not an important process in the fate of 3,3’,5,5’-tetramethyl-4,4’-diaminodicyclohexylmethane.
