- octanol-water
- Analytical method:
- other: UV-VIS
- Key result
- Type:
- log Pow
- Partition coefficient:
- 3.38
- Temp.:
- 20 °C
- Remarks on result:
- other: pH not specified
- Details on results:
- By means of the flask method, the saturation concentration of the test item in n-octanol was determined to: 3128 mg/L
By means of the flask method, the saturation concentration of the test item in water was determined to: 1.29 mg/L - Conclusions:
- The partition coefficient n-octanol/water of FAT 93450/Z at 20 °C was determined to be 3.38.
- Executive summary:
The partition coefficient of FAT 93450/Z was assessed in a study conducted according to OECD Guidelines 107 as well as 117 and EU Method A.8. Flask method was used to determine the solubility of the test substance in n-octanol. The partition coefficent n-octanol/water of FAT 93450/Z at 20 °C was calculated from the individual solubility in water and n-octanol, which were determined to be 3128 and 1.29 mg/L, respectively. From these values, the log Pow was calculated to be 3.38.
