Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Effect concentration:
23 mg/L

Additional information

A combined limit/range-finding test was performed. Because the substance was not completely soluble in test medium WAFs were prepared at a loading rates of 1, 10 and 100 mg/L. Analysis of the samples taken from the WAFs prepared at a loading rate of 100 mg/L showed that the initial measured concentration was 23 mg/L. This concentration remained stable during the test period and therefore effect parameters were based on the initial exposure concentration.

The substance did not induce acute immobilisation of Daphnia magna at 23 mg/L. The 48h-EC50 was >23 mg/L and therefore also beyond the water solubility limit.
