- 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.

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.
