Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The purpose of this study is to evaluate the stability of neodymium tris(di-2-ethylhexylphosphate) in deionized water and mineral water in a 10-day period. The objective is to determine whether the product dissociates (release the mineral and organic) and/or degrades (transformation of the organic part). In this context, the pH of neodymium tris(di-2-ethylhexylphosphate) was measured in deionized water.
- GLP compliance:
- no

The pH of this solution is stable during the 10-day period (pH = 6.2).
Applicant's summary and conclusion
- Conclusions:
- pH = 6.2 at 100 mg/L in deionized water.
- Executive summary:
The pH was measured during the study related to the stability in water (see section 4.23).
The product is slightly dissociated (< 2mg/L) at 100 mg/L in deionized water.
The pH of this solution is stable during 10 days (pH = 6.2).
