Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Acute toxicity to aquatic invertebrates was assessed in a 48 -hour study under static exposure conditons, following OECD guideline 202.
In a preliminary test at concentrations between 1 and 100 mg/l, concentration-related effects on mobility were seen. Based on such results, a main test was conducted at concentrations between 0.8 and 13.8 mg/l. Controls were run and were valid. Analytical monitoring demonstrated that test substance solution were stable during the testing period, thus effect levels were referred as nominal concentrations. Effect levels were determined at 24 h and 48 h after start of the study.
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.
