Key result
Water solubility:
<= 0 g/L
Conc. based on:
test mat.
Temp.:
20 °C
pH:
>= 8 - <= 8.4
Details on results:
In the samples taken at 48 and 72 hours no substance was detected. In the sample taken at 96 hours a small response at the retention time of the substance was observed in the chromatogram of the sample. The response was probably caused by contamination.
Conclusions:
The water solubility of the test item at 20°C was ≤ 4.4 x 10-7 g/L.
The pH of the aqueous samples was 8.0 – 8.4.
Executive summary:

The slow-stirring flask method was applied for the determination of the water solubility of 4,4'-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene). The water solubility of the test item at 20°C was ≤ 4.4 x 10-7 g/L. The pH of the aqueous samples was 8.0 – 8.4.
