Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
-Short-term toxicity to fish:
Key study. EU Method C.1 (Acute Toxicity for Fish).
The 96 hour LC50 of the test substance to Oncorhynchus mykiss was calculated to be 0.3 mg/l (with 95% confidence limits of 0.2 to 0.35 mg/l). LC50 (96h)=0.3 mg/l
-Short-term toxicity to daphnia:
Key study. EU Method C.2 (Acute Toxicity for Daphnia).
The 48 hour EC50 of the test substance to Daphnia magna was calculated to be 0.4 mg/l (with 95% confidence limits of 0.3 to 0.5 mg/l).
EC50 (48h)=0.4 mg/l
-Toxicity to aquatic algae:
Key study. The test was performed with procedure similar to OECD guideline 201.
Based on the average specific growth rate the 72 hour ErC50 of the test substance to S. capricornutum was observed to be 4.9 mg/l.
The no effect concentration (NOEC) of the test substance to S. capricomutum, based on the area under the growth curves, was calculated to be 1.6 mg/l. Based on the average specific growth rate the NOEC was calculated to be 2.8 mg/l
-Toxicity to microorganisms:
Key study: EEC activated sludge respiration inhibition test
The three hour EC20 value for the test substance (added as a solution in dimethyl sulphoxide) was 24 mg/l.
EC50 and EC80 concentrations could not be calculated as they exceeded the water solubility of the test substance.
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.
