Description of key information
Additional information
Short-term toxicity to fish: No data available.
Not required under REACH for this tonnage band.
Long-term toxicity to fish: No data available.
Not required under REACH for this tonnage band.
Short-term toxicity to aquatic invertebrates: With high probability not acutely harmful to aquatic invertebrates.
The key study with CAS 631-41-4 was performed according to EEC Directive, Method C.3. This GLP study was maintained under static conditions with nominal concentrations of 0 (control), 12.5, 25, 50 and 100 mg/L. The test concentrations were analytically confirmed by measurements of GE with UV/VIS detection at the start and at the end of the test duration. The the determined EC50 was > 100 mg/L after 48 hours of exposure.
Based on the available experimental data the substance is concluded to be with high probability acutely not harmful to aquatic invertebrates.
Long-term toxicity to aquatic invertebrates: No data available.
Not required under REACH for this tonnage band.
Toxicity to aquatic algae and cyanobacteria: No data available.
Not required under REACH for this tonnage band.
Toxicity to microorganisms: The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.
The assessment of the toxicity to microorganisms is derived on the available data from an inhibition control of a DOC-die-away test conducted according to EU method C.4-A (see also Section 5.2).
The results of the key study in Section 5.2 indicate that
a) The substance is not readily biodegradable (according to OECD criteria),
b) inhibitory effects of the substance to sewage sludge bacteria were not observed at the tested concentration 78 mg/L, and
c) the inhibition of the degradation potential of activated sludge is not anticipated when the substance is introduced in appropriately low concentrations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
