Key result
Water solubility:
121 g/L
Conc. based on:
test mat.
Loading of aqueous phase:
540 g/L
Incubation duration:
>= 0 - <= 72 h
Temp.:
20 °C
pH:
2.9
Remarks on result:
other: reported value = corrected for purity
Details on results:
- The mean of the concentrations after 24, 48 and 72 h was reported as the water solubility of the substance.
- Maximum difference (24, 48 and 72 h) meets the criterion of ≤ 15% (i.e. 2.9%)

- No test item was detected in the pretreated sample from the blank.
