Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- from 2017-11-07 to 2017-11-09
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- yes
- Remarks:
- see 'Principles of method if other than guideline'
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- yes
- Remarks:
- see 'Principles of method if other than guideline'
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7840 (Water Solubility)
- Deviations:
- yes
- Remarks:
- see 'Principles of method if other than guideline'
- Principles of method if other than guideline:
- A miscibility test was carried out to evaluate the solubility of Test Item in water. This procedure deviates from the guideline but is considered scientifically valid.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: miscibility test with visual inspection
- Key result
- Temp.:
- 20 °C
- pH:
- >= 11.63 - <= 13.05
- Remarks on result:
- completely miscible
- Details on results:
- The test item is miscible with water at room temperature.
- Conclusions:
- The test item is miscible with water at room temperature.
- Executive summary:
The water solubility was determined according to OECD 105, Regulation (EC) No. 440/2008 method A.6 and OPPTS 830.7840. In a preliminary test no saturated solution of the test item could not be prepared, therefore, the standard methods for determination of the water solubility are not feasible. Therefore, the water solubility of the test item was determined using the miscibility test with visual inspection.The test item was mixed with water in the following ratios: Test Item : Water = 1 : 9, 9 : 1, 1 : 1 (by weight). Miscibility was checked visually after vigorous shaking.The test item is miscible with water at room temperature (pH 11 - 13).
