Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC50 or LC50 for freshwater sediment:
6 617 mg/kg sediment dw
EC10, LC10 or NOEC for freshwater sediment:
1 255 mg/kg sediment dw

Additional information

A study investigating the toxicity of C12-14AS MEA (CAS 90583-16-7) to sediment organisms was conducted by Hudson (2003). Corophium sp. were exposed for 10 days in the laboratory under static conditions to 5 concentrations of the test item in seawater, ranging from 10 to 10000 mg/L. A LC50 and NOEC of 6617 and 1256 mg/L, respectively were determined.
