Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Acute aquatic toxicity data on all three trophic levels are available for the read-across substance. The studies showed no toxic effects within the range of solubility (the read-across justification is attached in chapter 13).
Additionally, preliminary data on the toxicity to fish and also data on the toxicity to Daphnia magna are available for the test substance itself showing no effects within the range of solubility. Therefore, the test substance is with high probability not acutely harmful to aquatic organisms.
Additionally, the Activated Sludge Respiration Inhibition Test for the read-across substance gave a NOEC > 100 mg/L after 3 h of incubation showing no effects on the toxicity to microorganisms. Therefore, the inhibition of the degradation activity of activated sludge is not anticipated when introduced to biological treatment plants in appropriate 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
