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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
In the Daphnia study, the semi-static design with change of media every 24 hours was predicted to be fully acceptable based on the stability study. The study was run as a limit test run at 100 mg/L. The end concentrations noted following analysis were unexpectedly below the 80% cutoff specified in the guidance. However, the EC50 is stated as > 100 mg/L, as no effects were seen in this study. In addition, the test was performed in a semi static-system and the degradation products of the main compound are compounds which are necessary for the proper use of the dye and are very similar in structure as can be seen in the hydrolysis study (see Chapter 5.1.2 of this dossier).
The substance is therefore not considered to be harmful to Daphnia.
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.
