Results and discussion
Water solubility
- Water solubility:
- >= 23.6 - <= 24.3 mg/L
- Conc. based on:
- test mat.
- Incubation duration:
- >= 24 - <= 72 h
- Temp.:
- 20 °C
- pH:
- >= 4.1 - <= 4.9
- Details on results:
- The maximum difference of the concentrations determined in the 24, 48 and 72 hour test samples was ≤ 15%. Based on this, the water solubility of the test item is given as the mean value of the analyzed concentrations.
No test item was detected in the pretreated sample from the blank water mixture. The pH of the aqueous samples was between 4.1 and 4.9.
Applicant's summary and conclusion
- Conclusions:
- The flask method was applied for the determination of the water solubility of CH02241.
The water solubility of the test item at 20°C was 23.9 g/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
