Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 17.06.1991 to 21.06.1991
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- no
- GLP compliance:
- yes
- Remarks:
- Swiss GLP
- Type of method:
- flask method
- Specific details on test material used for the study:
- Name: FAT 40406/A
Purity: 89.3 % - Water solubility:
- 339 g/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- 7.3
- Details on results:
- The substance forms a viscose paste at a concentration of 1000 g/L. Therefore it is not possible to use a five fold saturation concentration for the determination of the solubility, as required by the EEC method. Consequently the solubility can be higher than this mean value.
- Conclusions:
- The water solubility of the FAT 40406/A was found to be 339 g/L at 20 °C.
- Executive summary:
A GLP-compliant study was performed on FAT 40406/A according to EU Method A.6 and OECD test guideline 105, as per flask method to assess the water solubility of the test substance. Based on the findings of the study, the water solubility was found to be 339 g/L at 20 °C.
