Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 238-122-3 | CAS number: 14246-53-8
Toxicity to microorganisms
Administrative data
- 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

Results and discussion
Applicant's summary and conclusion
- Conclusions:
- The substance is not considered to be toxic towards the inoculum (activated sludge from a biological STP) the aerobic activated sludge micro organisms because degradation was > 25 % within 14 days.
According to REACH Annex VIII criteria, a standard assay on inhibition of respiration of activated sludge is not required as the substance is readily biodegradable at the tested concentration of 34 mg/L; this concentration has not been compared with the concentrations which may reach STP, since environmental exposure assessment is not required in the absence of classification for ecotoxic potential. - Executive summary:
