- Main Study- first eluting test item peak (most polar constituent)
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 analysed concentrations.
No test item was detected in the pretreated sample from the blank water mixture.
The maximum difference of the concentrations determined in the 24-, 48- and 72- hour test samples was >15%. No test item was detected in the pretreated sample from the blank water mixture. Since tendency in increasing concertation was observed it was decided to repeat the main study with longer stirring time. The maximum difference of the concentrations determined in the 72-, 96- and 120- hour test samples was >15%. The 72-hour measurement was lower than 72-hour measurement during the main study 1. Results are not conclusive therefore water solubility is given as a range of all measurements. Small responses at the retention time of the test item were detected in the chromatograms of the pretreated sample from the blank water mixture. It was considered to derive from carry-over in the analytical system since similar responses were found in the analytical blanks. The maximum contribution to the samples was 2.2%. It was considered that it has no significant effect on the results of the test samples.
Main Study- last eluting test item peak (least polar constituent)
During first main study no trend in analysed concentrations was observed. Furthermore, analysed concentrations were mainly extrapolated from the calibration curve therefore it was decided to repeat the study.
At the loading rate of 0.15 g/L and 2.5 g/L the maximum difference between the concentrations determined in the 24-, 48- and 72- hour test samples was > 15%. The measured concentrations did not show any trend. Based on this, the water solubility of the test item is given as the mean value of all analyzed concentrations.
At the loading rate of 0.3 g/L, the 24-hour measurement was significantly higher than the 48- and 72- hour measurements (maximum difference > 15%). Based on this, the water solubility of the test item was given as the mean value of the 48- and 72-hour measurements.
No test item was detected in the pretreated sample from the blank water mixture. - Conclusions:
- The slow-stirring flask method was applied for the determination of the water solubility of ISO-MIX due to its potential volatility. Since test item is multi-constituent water solubility was been determine at least 2 loading rates for most and least polar constituent.
The water solubility of the most polar constituent at loading rate of 5 g/L and at 20°C was 4.40 g/L. The pH of the aqueous samples was 6.3 and 6.5.
The water solubility of the most polar constituent at loading rate of 250 g/L and at 20°C was in the range of 41.5 to 59.2 g/L. The pH of the aqueous samples was 6.0 and 5.9.
The water solubility of the least polar constituent at loading rate of 0.15 g/L and at 20°C was 0.103 g/L. The pH of the aqueous samples was 6.8 and 6.9.
The water solubility of the least polar constituent at loading rate of 0.3 g/L and at 20°C was 0.123 g/L. The pH of the aqueous samples was 6.6 and 6.8.
The water solubility of the least polar constituent at loading rate of 2.5 g/L and at 20°C was 0.122 g/L. The pH of the aqueous samples was 6.8 and 6.9. - Executive summary:
