Propanoic acid, 2-hydroxy-, C12-15-alkyl esters

Toxicity to microorganisms

Link to relevant study record(s)

Reference

Endpoint:

activated sludge respiration inhibition testing

Data waiving:

study scientifically not necessary / other information available

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

Microbial activity was not inhibited in a biodegradation test at a loading of 40 mg/L and the alkyl esters were readily biodegradable.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:

40 mg/L
