Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Relevant distribution into the sediment compartment and exposure of sediment organisms is not expected.

Key value for chemical safety assessment

EC50 or LC50 for marine water sediment:
875.47 mg/kg sediment dw

Additional information

Since the physicochemical data indicate that the substance is not very adsorptive or bioaccumulative, a relevant distribution into the sediment compartment and a considerable exposure of sediment organisms is not expected.


The sediment toxicity was tested in a short term sediment toxicity study according to US EPA 600/4-85/013. The test organisms Corophium volutator was collected from a site in the Bay of Suckquoy, near Sebay farm in Orkney and acclimated to laboratory conditions for seven days prior to testing. The exposure time was 10 days. The test substance exhibited a 10 day LC50 value of 875.47 mg/kg sediment dw.
