Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Two measured values are available for the acute toxicity in daphnia magna. One study established that the EC0 was in excess of the maximum tested dose of 500mg/l whilst a second study established that the LC50 was in excess of the maximum tested dose of 10000mg/l. A QSAR predicts that the EC50 is much higher at around 47000mg/l. On this basis, it seems reasonable to conclude that the acute toxicity EC50 is likely to be in excess of 10000mg/l and that selecting this value is a conservative choice for the key parameter. There is no data availalble on marine invertebrates.
