Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
As SAS is readily biodegradable and not strongly adsorptive to solids, e.g. sediment, exposure of sediment is limited. According REACH Regulation 2006/1907/EEC, Annex X, 9.4, column 2, sediment effects studies need only to be carried out if direct and indirect exposure is indicated by the chemical safety assessment. As demonstrated in the CSR chapters 9 and 10, sediment exposure and risk is very low.
Nevertheless a 3-day chronic nematode study was carried out resulting in a NOEC reproduction of 939 mg/kg dw. Based on this NOEC a PNEC freshwater sediment of 9.4 mg/kg dw (a.i.) was calculated and can be compared with the PNEC freshwater sediment equil. partit. of 2.9 mg/kg dw based on aquatic effect data.

Additional information
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.
