Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: external method EM/00408/01 from Competence Center Analytics, BASF SE (chapter 4: visual method)
- Principles of method if other than guideline:
- The water solubility of substances with an expected high solubility
is normally determined according to the flask method described
in the OECD Guideline for the Testing of Chemicals 105.
To apply this method, the preparation of a saturated solution of
test item in water is required. Since this is not feasible for test
items with a very high or complete solubility, a homemade method
described in the external method EM/00408/01 from Competence
Center Analytics, BASF SE (chapter 4: visual method) was
applied to investigate complete miscibility. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method

| 5.0825 | 4.9830 | 50.49 | 1:1 | The test item is miscible with water after shortly shaking by hand. Clear, colourless mixture | 4.1 |
| 7.0097 | 2.9918 | 70.09 | 7:3 | The test item is miscible with water after shortly shaking by hand. Clear, colourless mixture | 4.3 |
| 8.9990 | 1.0389 | 89.65 | 9:1 | The test item is miscible with water after shortly shaking by hand. Clear, colourless mixture | 5.0 |
After conditioning overnight at 20.0°C ± 0.5°C, no changes were
observed.
Water solubility
The test item is miscible with water at room temperature
(T = 23 °C) and at T = 20.0 °C ± 0.5 °C in any ratio.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
