Results and discussion

Water solubility
Water solubility:
293.2 g/L
Temp.:
25 °C
Remarks on result:
other: pH 9.95-10.03
Details on results:
The standards used for the quantification of the test item in the test solutions showed satisfactory agreement through the run and between them. The % RSD of the area of the 5 injections of Standard 1A was within the 5% acceptance criteria. The % RSD of the retention time of the 5 injections of Standard 1A was also within the 1% acceptance criteria, therefore confirming the suitability of the method.

OECD Guideline 105 states that if the concentrations measured in at least the two of the last Tests (e.g Test 2 and Test 3) do not differ by more than 15%, as it is the case in this study, the test is satisfactory.
The average result from Test 1, Test 2 and Test 3 was reported as a final result for the water solubility test:
29.3 % w/v at 25 C +/- 1 C

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The water solubility of the test material was determined to be 293.2 g/l in this study. Therefore the test material is very soluble in water.
Executive summary:

Introduction

This study was undertaken to determine the water solubility of the test material. The method used was compatible with OECD Guideline 105 (Flask Method).

Results & Conclusions

The water solubility of the test material was determined to be 293.2 g/L in this study. Therefore the test material is very soluble.
