Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Study design

Total exposure duration:
48 h
Post exposure observation period:
not applicable

Test conditions

Hardness:
250 mg/L expressed as CaCO3
Test temperature:
Blank control during the study: 19.6 - 20.4°C
pH:
At t=0h and t=48h
Control: 7.8 - 7.8
Test samples: 7.8 - 7.9
Dissolved oxygen:
At t=0h and t=48h [mg/L]
Control: 7.8 - 8.0
Test samples: 8.2 - 8.5
Salinity:
not applicable
Nominal and measured concentrations:
As the submission substance was insoluble in water (< 10µg/L), analytical verification was impossible due to sensitivity limitations. Therefore, in a limit test the nominal substance concentration of 100 mg/L in test medium was applied after filtration through a 0.45 µm membrane filter.
