Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Three chronic studies are available in invertebrates. All showed consistent results. The 21 day studies using daphnia magna are considered the most reliable as these are full guideline studies with no significant shortcomings. The third study in ceriodaphnia was only for 7 days and, whilst the NOEC for reproduction was slightly lower than for the first study, there was no clear dose response relationship observed which means some uncertainty is associated with the result. The two daphnia magna studies with idential results are therefore used for the key parameter. There is no chronic data available in saltwater species.
