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.

Key value for chemical safety assessment

Water solubility:

0 g/L

at the temperature of:

20 °C
