Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The long-term toxicity to aquatic invertebrates was assessed under semi-static conditions in an OECD 211 study using Daphnia magna as test organism (MITI, 2000; report no. 9B484G). The test concentrations were analytically verified and were stable during the exposure; therefore, the results are expressed on nominal concentrations. The pH of the test solutions was within acceptable guideline specifications and did not need to be adjusted. The study fullfilled all validity criteria according to OECD guideline 211.
Based on reproduction, the following effect values were determined: 21-d NOEC = 14 mg/L, 21-d EC50 = 48.5 (based on nominal concentrations, verified by analytical measurement).
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.
