- Type of method:
- flask method
- Partition coefficient type:
- octanol-water
- Key result
- Type:
- log Pow
- Partition coefficient:
- ca. 1.4
- Temp.:
- 20 °C
- pH:
- ca. 6
- Conclusions:
- The partition coefficient (n-octanol/water) of the test item was estimated on the ration of the individual solubilities of the test item in water and n-octanol. The solubilities were determined according to the flask method. The partition coefficient Pow of the test item was estimated to:
logPow (loading rate 10g/l) < 0.6
log Pow (loading rate 1 g/l) < 1.4 - Executive summary:
The partition coefficient (n-octanol/water) of the test item was estimated on the ration of the individual solubilities of the test item in water and n-octanol. The solubilities were determined according to the flask method. The partition coefficient Pow of the test item was estimated to:
logPow (loading rate 10g/l) < 0.6
log Pow (loading rate 1 g/l) < 1.4
