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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
A test on the toxicity of the substance to sediment organisms is not available. The PNEC sediment assessment is based on data on the structural analogue CAS 5281-04-9. The analogue substance is composed of a structurally analogue organic part laked with a different metal (Ca2+).
Due to the laking a disintegration of the molecule at pH values relevant in the environment is not expected. Thus an effect or a release of the metal part is not likely. Therefore a transfer of the results obtained for structural related substances to CAS 17852-98-1 is feasible (see Annex). The effect of the analogue substance on sediment organisms was tested in an OECD guideline study (OECD 225). Animals of the species Lumbriculus variegatus were exposed to the substance in a sediment-water system for 28 days. Based on mortality, reproduction and biomass a NOEC of 1000 mg/kg sediment dry weight was observed (Dr. U. Noack-Laboratorien, 2010).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.
