Applicant's summary and conclusion
- Conclusions:
- The test item was miscible with water at room temperature (T = 24 °C) and at T = 20.0 °C ± 0.5 °C in any ratio.
- Executive summary:
The water solubility of test items with an expected high solubility is normally determined according to the "flask method" described in the OECD test guideline 105. To apply this method,the preparation of asaturated solution of the test item in water is required. Since this wasnot applicable for the present test item,as according to the preliminary test the test item was completely miscible with water,a special "visual method" was applied to investigate the complete miscibility:
The test item was miscible with water at room temperature (T= 24°C) and at T =20.0 °C ± 0.5 °C in any ratio.
