Reference
Preliminary estimation
Mass of sample (mg) | Volume of octanol in which sample dissolves (mL) | Estimated solubility (g/L) |
10,000 | 10 | >1,000 |
Main test
The test material was found to be fully miscible in water and n-octanol, therefore formal testing was not possible. In accordance with the test guidance the Partition Coefficient was
estimated using prediction software (KOWWIN v1.68).
The calculated logPow using SMILES input was 1.05.
Description of key information
Based on a guideline study (K1, Dekra, 2014), the test material was found to be insoluble and fully miscible in octanol ratios of 1:1, 1:2 and 2:1 of test material / octanol. Therefore, the partition coefficient of the test item was calculated to be: Log Kow (KOWWIN v1.68 estimated) = 1.05.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 1.05
- at the temperature of:
- 20 °C
