Reference
Preliminary Visual Estimation of the Water Solubility
The solubility of the test item in water was found to be below 3.2 mg/L (without correction of the purity). Therefore the column elution method was performed for the determination of the water solubility of the test item.
Column elution method
The coating check was successful.
According to the guideline, the data of the fractions 1 to 5 were not taken into account for the following evaluation. The values for the water solubility were calculated from fractions 28 to 42 for column 1, from the fractions 67 to 81 for column 2 and from the fractions 42 to 56 for column 3. All other fractions were discarded.
Result column 1: Evaluation of the fractions 28 to 42: Average value of the water solubility for column 1: 108 µg/L
Result column 2: Evaluation of the fractions 67 to 81: Average value of the water solubility for column 2: 83 µg/L
Result column 3: Evaluation of the fractions 42 to 56: The blank concentration was found to be below the quantification limit of 38 µg/L
Average water solubility of column 1 and 2: 96 µg/L
Description of key information
The water solubility of the test item was tested according to EU Method A.6 and OECD Guideline 105 in a non-GLP study at 20 °C. The water solubility at this temperature is 96 µg/L.
Key value for chemical safety assessment
- Water solubility:
- 96 µg/L
- at the temperature of:
- 20 °C
