Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

This endpoint is not a mandatory data requirement according to Annex IX of Regulation (EC) No 1907/2006.

According to column 2 of Regulation (EC) 1907/2006 Annex IX long-term toxicity testing shall only be proposed if the chemical safety assessment indicates the need to investigate further the effects on sediments organisms. The substance does not need further investigations due to the following reasons. As the test substance is highly insoluble in water (< 0.05 mg/L) it is expected that sediments are, if at all, only exposed to very small amounts of the test substance.The Guidance on information requirements and chemical safety assessment, Chapter R.7b (ECHA, 2017) states that once insoluble chemicals enter a standard STP, they will be extensively removed in the primary settling tank and fat trap and thus, only limited amounts will get in contact with activated sludge organisms. Nevertheless, once this contact takes place, these substances are expected to be removed from the water column to a significant degree by adsorption to sewage sludge (Guidance on information requirements and chemical safety assessment, Chapter R.7b, (ECHA, 2017). Thus, only limited concentrations of the substance will presumably be discharged to the aqueous/sediment compartment. Thus, due to the low expected environmental concentrations of the substance a chronic exposure of sediment organisms is unlikely.Furthermore, no effects on aquatic algae, daphnia and fish were observed in the range of water solubility. Since only low amounts of the test substance can be expected in the aquatic environment and no adverse effects of the substance are expected no long-term tests on sediment organisms should be performed.
