Data waiving:
other justification
Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable
Justification for type of information:
TRIS HCl is readily biodegradable and is therefore expected to be degraded by microorganisms in the environment within a short period of time. Since it will be eliminated by biodegradation, hydrolysis is not relevant for this substance.

Description of key information

Since the substance is readily biodegradable, it is expected to be eliminated from the aquatic environment within a short period of time. In accordance with column 2 of Annex VIII of EC 1907/2006, testing for hydrolysis is not required as the substance is readily biodegradable.
