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:
- 20 May 1992 to 17 July 1992
- 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:
- equivalent or similar to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- GLP compliance:
- yes
- Type of method:
- flask method
- Specific details on test material used for the study:
- Substance name: Erionyl Rot HT 3728
The test substance is a black - green powder - Water solubility:
- > 48 g/L
- Temp.:
- 20 °C
- pH:
- 7.5
- Details on results:
- In a preliminary study the approximate solubility was >100 g/L.
- Conclusions:
- The water solubility of FAT 45155/B is at least 48 g/L solution at 20 °C.
- Executive summary:
A GLP-compliant water solubility study with FAT 45155/B was carried out according to EEC guideline L 251/A.6, (based on OECD No. 105) using flask method. Based on the study findings, the water solubility of the test substance was determined to be greater than 48 g/L solution at 20 °C, indicating it is very soluble in water.

Results:
Flask | 1 | 2 | 3 |
Weight of the test substance (g) | 0.31 | 0.32 | 0.31 |
Volume of water (ml) | 6.0 | 6.0 | 6.0 |
Temperature during agitation (°C) | 30 | 30 | 30 |
Agitation time (hrs) | 24 | 48 | 72 |
Temperature of equilibration (°C) | 20 | 20 | 20 |
Equilibration time (hrs) | 24 | 24 | 24 |
pH of the solution at 20 °C (bevor centrifugation) | 7.5 | 7.5 | 7.5 |
Water solubility (g/l) | 45.8 | 48.4 | 49.6 |
Mean value (g/l) solution | 48 |
Comments: The test substance forms a very high viscose solution at the concentration of 100 g/l and shows thixotropic property. It is not possible to use a five fold saturation concentration for the determination of the solubility as required by the EEC method. 0.3 g test substance and 6 ml water form a handling solution.
