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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Multiple representative alkarylsulfonate compounds have been tested for toxicity to freshwater fish including Fathead minnow, Rainbow trout and Zebra fish at loading rates up to 1000 mg/L. No toxicity was observed in any study with any substance at any concentration tested. Therefore the NOEC for freshwater fish is 1000 mg/L WAF. Multiple representative alkarylsulfonate compounds have been tested for toxicity to the Sheepshead minnow, a marine fish, at loading rates up to 10,000 mg/L. No toxicity was observed in any study with any substance at any concentration. Therefore the NOEC for marine fish is 10,000 mg/L WAF.

Additional information
Freshwater fish: Representative alkarylsulfonate salts have been tested in two seperate testing programs by the American Chemistry Council. In addition, the registrant has proprietary data for an additional substance. While all studies are equally valid, the study on CAS# 61789-86-4 is selected as the Key Study to fulfill the endpoint requirement as the substance most chemically similar to the substance being registered based on primary alkyl range used for manufacture and metal salt (calcium) used for neutralization. However, because all studies are equally valid and because no toxicity to freshwater fish was observed in any study with any alkaryl sulfonate at any concentration tested, the findings at the highest WAF prepared with concentrations up to 1000 mg/L are used to develop the PNEC for freshwater fish. The NOEC for freshwater fish based on all available data is 1000 mg/L WAF.
Marine fish: Representative alkarylsulfonate salts have been tested by the American Chemistry Council. While all studies are equally valid, the study on CMA 504 is selected as the Key Study to fulfill the endpoint requirement as the substance most chemically similar to the substance being registered based on primary alkyl range used for manufacture and metal salt (calcium) used for neutralization. In this study, the substance was tested in a WAF prepared with concentrations up to 10,000 mg/L loading rate. No toxicity to marine fish was observed in any study at any loading rate tested. The NOEC for marine fish based on all available data is 10,000 mg/L WAF.
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.
