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:
- 1989
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Version / remarks:
- - EEC directive 84/449 A.6
- Deviations:
- yes
- Remarks:
- - The flask method was used instead of the column method because a change in crystal structure might occur when the test substance is deposited on the support material.
- GLP compliance:
- no
- Type of method:
- flask method
- Water solubility:
- 0.006 g/L
- Temp.:
- 20 °C
- pH:
- 6.7 - 6.8
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility of test substance was determined to be 0.0059 g/L at 20°C at pH 6.8 - Executive summary:
In this guideline (EU A. 6) study, the solubility of the test material (EC 404-360-3) was determined to be 0.0059 g/L at 20°C at pH 6.8
