Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Five valid aquatic toxicity studies are available: a 96-hour study in fish (Oncorhynchus mykiss); a 48 -hour study in Daphnia magna; a 72-hour study in Alage (Selenastrum capricornutum); a 21 day long term Daphnia Magna reproduction study and an activated sludge respiration inhibition test.
Due to the low water solubility of the registration material, nominal concentrations or WAF loading rates were used to set the dose groups in each study.
Adverse or toxic effects were observed in all aquatic toxicity studies with the following results:
Oncorhynchus mykiss (LL50 (96h) = 1.5 mg/L; OECD 203)
Daphnia magna (EL50 (48h) = 0.09 mg/L; OECD 202)
Selenastrum capricornutum (ErL50 (72h) = 0.31 mg/L; NOELr (72h) = 0.13 mg/L)
Daphnia magna (NOEL reproduction, mortality and growth = 0.14 mg/L; LOEL reproduction = 0.35 mg/L).
No significant adverse effects were observed in an activated sludge respiration inhibition test up to the highest concentration tested (NOEC >= 50 mg/L).
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.
