Any other information on results incl. tables
* Deviations from the Study Plan
The following deviations from the study plan were documented; in the preliminary test the nominal load 200 g/L was tested instead of 20 g/L. This was considered as uncritical as an excess of the test item was necessary in the preliminary test and a higher excess was used. The deviation was assessed and signed by the study director on 02. Apr. 2019.
The calibration was not renewed although the recovery rate of QC sample was higher than 115 %. This was considered as uncritical as a fresh prepared QC sample was measured and the recovery rate lay in the range of 100±15 %. The deviation was assessed and signed by the study director on 09. Apr. 2019.
Applicant's summary and conclusion
- Conclusions:
- According to OECD 105, the water solubility of the test item is:
1.19 ± 0.08 g/L at 20.0 ± 0.5 °C and pH 4.21 – 4.28
= 1.19 ± 0.08 kg/m3(SI units)
(mean value ± standard deviation)
