Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Under the conditions of the test the EC50 > 100 mg/L. The substance is not considered to pose a hazard to Daphnia Magna

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
500 mg/L

Additional information

Testing of Reaktiv-Rot F-66 813 FW for acute toxicity in Daphnia magna (water flea) over a total of 48 hours yielded the following immobility values:

 

after 24 hours (mg/L)    after 48 hours (mg/L)

EC0      1000                          560

EC50       > 1000                > 1000

 

The concentrations tested were 0 / 560 / 1000 mg/L. Immobility was observed at 1000 mg/L.

In order to determine the substance concentration, water samples were taken at study end. All mean values were above 80 % of the nominal concentration.
