Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The 48-hour EC50 value was determined by Spearman-Kärber estimates to be 7.5 mg a.i./L, with 95% confidence intervals of 6.4 to 8.8 mg a.i./L.  The No-Observed-Effect Concentration (NOEC) was determined to be 1.3 mg a.i./L.  The highest concentration producing 0% immobilization was 1.3 mg a.i./L.  The lowest concentration producing 100% immobilization was 13 mg a.i./L.

Additional information

In a GLP compliant guideline, the effect of the test substance on Daphnia magna was determined. The 48 hour EC50 value was determined by Spearman-Kärber estimates with the No-Observed-Effect Concentration (NOEC) reported. The limits of test substance concentration producing 0% and 100% immobilisation are indicated.
