Justification for data waiving:
the study does not need to be conducted because the substance is found to be readily biodegradable and the applied test concentrations are in the range of concentrations that can be expected in the influent of a sewage treatment plant

Description of key information

In a ready biodegradability screening study (Givaudan 2012), Isobutavan was found to be readily biodegradable and no toxicity was observed at the test concentration of 30 mg/L. This concentration can be considered as a NOEC for the toxicity to STP microorganisms.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
30 mg/L
