Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Since the reaction mass or the majority of its components are neither considered as readily nor as inherently biodegradable, no significant degradation of the reaction mass is expected. However, there is some evidence that piperazine may be considered as readily biodegradable. Based on the available screening data significant biodegradation cannot be expected for the reaction mass in the environment. This finding is supported by the chemical structures of 2 -piperazin-1 -ylethanol and piperazin-1,4 -diethanol which indicate a low potential for biodegradation. Therefore, no further tests on biodegradation are performed because it is not expected that further testing will significantly change this assessment.
