Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No study investigating the hydrolysis of Atmer 163 (CAS No. 97925-95-6) is available because it is technically not feasible. According to Regulation (EC) No 1907/2006, Annex XI, column 2 testing for a specific endpoint may be omitted if it is technically not possible to conduct the study as a consequence of the properties of the test substance. Since the test substance is a mixture of tertiary amines it is not possible to distinguish between the parent compound and the degradation products which are also amines with analytical methods. Hence, the testing on hydrolysis is technically not feasible.
