Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aquatic toxicity of PFBSK+ is well-studied, with a mixture of guideline studies provided by registrants or published in peer-reviewed scientific journals, as well as published non-guideline studies which were scientifically valid and applicable to regulatory endpoints. In the few cases where the free acid or an unspecified salt was used, experimental conditions indicate that the tested substance was entirely dissociated. The outcome was, therefore, equivalent to testing on the potassium salt. In addition to the aforementioned results, data from more exploratory in vivo and in vitro experiments lacking ready application to regulatory endpoints are available. Because the REACH guidance does not provide information useful for the interpretation of this last group of studies for the evaluation of toxicity, hazard assessment, and Classification & Labelling, data provided herein are to offer additional perspective on the scopes of current published research.
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.
