Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hydrolysis was found to be extremely low under most environmental conditions. The hydrolysis of DEGDN was quite slow (t1/2 > 800 days) at pH 7. However, hydrolysis increased as the pH increased; the half-life values at pH 9, 10 and 12.8 were 440, 530 and 130 days, respectively.

Key value for chemical safety assessment

Half-life for hydrolysis:
800 d
at the temperature of:
25 °C
