Materials and methods
- Principles of method if other than guideline:
- Under consideration of the expected value of the water solubility a suitable analytical method is not possible to perform. Bearing this in mind, the
calculated values of the QSAR methods are taken for a evaluation of the water solubility. Therefore the substance can be assumed as highly insoluble
in water (< 0.1 mg/l at 25 °C). - Type of method:
- other: WATERNT 1.01 and WSKOWWIN 1.42 (“EPISUITE”) were used for calculation

Results and discussion
Water solubility
- Water solubility:
- < 0.1 mg/L
- Temp.:
- 25 °C
- Details on results:
- Both QSAR methods show that the substance is highly insoluble in water. The calculation by WATERNT 1.01 reaches the calculation minimal limit of
1.1154 * 10-6 mg/l at 25 °C (1.1154 nanogrammes/liter). The calculation by WSKOWWIN 1.42 shows a value of 1.14 * 10-14 mg/l at 25 °C
(11.4 attogrammes/liter).
Any other information on results incl. tables
Because of the type of method (calculation) no pH value can be given.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
It can be concluded that the substance is highly insoluble in water (water solubility < 0.1 mg/L at 25 °C). - Executive summary:
Due to the physical properties of the substance and the lack of a suitable analytical method an experimental derived value is not available. Accurate measurements of the water solubility of high molecular weight organic compounds like dye in this case are notoriously difficult. QSAR values of the water solubility are very low (1.14 * 10-14 mg/L at 25 °C) or below the calculation limit of a method (< 1.1154 * 10-6 mg/L at 25 °C).
