Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- yes
- Remarks:
- Solubility is below 10-2 g/l, so the column elution method should be applied according to the guideline. Therefore the flask method was applied.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method

Applicant's summary and conclusion
- Conclusions:
- Water solubility of Neodymium fluoride oxide, magnesium doped was determined to be 0.12 mg/L at 20 °C.
- Executive summary:
In the course of this study water solubility of Neodymium fluoride oxide, magnesium doped was investigated using the shake flask method. Water solubility was calculated based on the neodymium concentration measured in water by a previously validated ICP-OES method. Water solubility of Neodymium fluoride oxide, magnesium doped was determined to be 0.12 mg/L at 20 °C.
