- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 18 February 1987 to 27 February 1987
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- not specified

- Type of method:
- flask method
- Specific details on test material used for the study:
- Product designation: Monoazo Yellow TZ 2382
Identification: FAT 40224/C
Vers. 10/86 Op. 1/86 - Water solubility:
- 341 g/L
- Temp.:
- 20 °C
- pH:
- >= 6.4 - <= 7
- Remarks on result:
- other: Other details are not provided
- Details on results:
- The substance forms a paste at a concentration of 2000 g/L. Therefore, it is not possible to use a five fold saturation concentration for the determination of solubility, as required by the EC method. Consequently, the solubility can be higher than this mean value.
- Conclusions:
- The water solubility of FAT 40224/C was 341 g/L at 20 °C.
- Executive summary:
In a GLP-compliant study with FAT 40224/C, performed according to EU method A.6 using flask method. Based on the study results, the water solubility of the test substance was determined to be 341 g/L at 20 °C. Experiments were performed in triplicate.
