Results and discussion

Water solubility

Key result

Water solubility:

0.177 - 0.411 mg/L

Conc. based on:

test mat.

Temp.:

20 °C

pH:

5.9 - 6.25

Remarks on result:

other: Mean at the plateau was 0.276 ± 0.094 mg/L

Applicant's summary and conclusion

Conclusions:

The concentration of the test item in water was stated as
0.276 ± 0.094 mg/L at 20.0 ± 0.5 °C and pH 5.90 – 6.25
0.276 ± 0.094 * 10-3 kg/m3 (SI units)

Executive summary:

In the main test, six different loading rates in the range of 100 – 1000 mg/L were chosen.
Dependency of solubility on amount of the test item (nominal load) was not perceived. The
solubility of the test item in water was in the range of 0.177 – 0.411 mg/L. Mean at the
plateau was 0.276 ± 0.094 mg/L.
