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:
- 02 July 1984 to 09 July 1984
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- not specified
- GLP compliance:
- yes
- Type of method:
- flask method
- Specific details on test material used for the study:
- Product: Monoazo Yellow HT 2025
Identification: FAT 20'306/B - Water solubility:
- > 100 g/L
- Temp.:
- 23 °C
- Remarks on result:
- other: no additional information was provided.
- Details on results:
- The substance forms a paste at a conc. of 400 g/l. Thus it is not possible to use a five fold saturation concentration for the determination of solubility as required by the OECD method.
- Conclusions:
- The water solubility of FAT 20306/B was determined to be > 100 g/L at 23 °C.
- Executive summary:
A GLP-compliant test with FAT 20306/B was carried out according to OECD guideline 105 using flask method. Based on the test results, the water solubility of test substance, related to pure substance, is >100 g/l at 23 °C.
