Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The 96 hour LC50 of the registered substance in 30% solution was >1800 mg/l. As the test material was provided as a 30% solution the LC50 was corrected to reflect the dilution of the substance in the solution. After 96 hours exposure in this study the LC50 value was determined to be >540(corrected) mg/l i.e. higher than the maximum concentration tested. As no upper limit was provided for the LC50 of the test material it was not possible to calculate the toxicity of the registered substance above 540 mg/L.
Key value for chemical safety assessment

Additional information
The acute toxicity of the a solution containing 30% of the registered substance to fish was determined in accordance with the OECD Guideline for Testing of Chemicals 203 adapted by OSPARCOM (1995) for marine testing of offshore chemicals.
The species used for the test was Scophthalmus maximus (juvenile turbot), which was tested under semi-static conditions for 96 hours. The 96 hour LC50 of the test material in the solution was >1800 mg/l. As no upper limit was provided for the LC50 of the test material it was not possible to accurately calculate the toxicity of the registered substance included in the solution. However, as the solution contains approximately 30% of Ethanolamine Salt of Aryl Sulphonamido-Carboxylic Acid the corrected LC50 is > 540 mg/L which is considered unlikely to be toxic to fish. In addition an equivalent study of Monoethanolamine, the most hazardous component of the registered substance showed an LC50 of 440 mg/L which is unlikely to be cause acute toxicity to fish.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).
