Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a 96-h acute toxicity study of the test item to zebra-fish (B. rerio) under static conditions the NOEC was estimated to be 26.5 mg/L and the LC50 was estimated to be > 26.5 mg/L (mean measured concentrations).
The 48-h NOEC of the test item to D. magna was estimated to be 2.4 mg/L, the 48-h EC50 of the test item to D. magna was estimated to be 4.4 mg/L (mean measuerd concentrations) with confidential limits ranging from 3.1 mg/L to 6.1 mg/L.
The test substance exhibits a very low water solubility (0.8 mg/L). Therefore, bioavailability to aquatic organisms is strongly limited. All effect concentrations are well above the water solubility. In conclusion, the substance shows no effect in the range of water solubility and no long-term toxicity test was performed with regard to animal welfare.
The IC50 of the test item to microorganisms was estimated to be > 320 mg/L, based on nominal 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.
