Results and discussion

Water solubility
Key result
Water solubility:
ca. 332 g/L
Conc. based on:
test mat.
Temp.:
20 °C
pH:
1.1 - 1.3
Details on results:
The maximum difference of the concentrations determined in the 24, 48 and 72 hour test samples was ≤ 15%. Based on this, the water solubility of the test item is given as the mean value of the analyzed concentrations.
A small response at the retention time of the test item was detected in the chromatogram of the blank water mixture. The maximum contribution to the lowest samples was 0.0094%. It was considered that it has no significant effect on the results of the test samples.
No test item was detected in the pretreated sample from the blank water mixture.
