Results and discussion
Water solubility
- Water solubility:
- < 0.001 g/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- Remarks on result:
- other: No data on pH value was provided. pH-value see 4.20.
Any other information on results incl. tables
Preliminary estimation:
| Mass of sample (mg) | Volume of water in which sample dissolves (ml) | Estimated solubility (g.L-1 ) | Analysis method |
| 1 | 1001 | < 0.01 | N/A |
Estimated Water Solubility (g.L-1): < 0.001.
Analysis Apparatus, Method and Test Conditions:
Temperature of determination (°C) : 20 ; pH of water : 7.08 .
Comment: For the preliminary estimation the majority of the 1 mg of sample did not dissolve in water after shaking and sonication for 30 minutes. Therefore it is expected that the solubility of the sample is below the limit of detection on the HPLC system.
Applicant's summary and conclusion
- Conclusions:
- The test subtance Fatty Acids, C14-C18 and C16-18-unsatd., ammonium salts is difficult to dissolve or insoluble in water (Water Solubility (20°C): <1 mg/L).
- Executive summary:
Water Solubility of Fatty Acids, C14-C18 and C16-18-unsatd., ammonium salts at 20°C is <1 mg/L.
