Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Data on all three trophic levels are available for the test substance. Due to the low solubility of the test item saturated solutions have been prepared in all studies. The short-term toxicity to fish, aquatic invertebrates and algae showed no effects up to the limit of solubility and the L(E)C50 was determined to be > 100 mg/L (nominal, loading rate).
Therefore, the test substance is with high probability not acutely harmful to aquatic organisms.
Additionally, the Activated Sludge Respiration Inhibition Test gave an ErC10 > 1000 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.
