Description of key information
Based on the available data from study report,the partition Coefficient n-octanol/water of test chemical was determined by Shake Flask Method. The study was performed at a temperature of 27°C and pH 8.53. The log Pow value was determined to be -1.283 at a temperature of 27°C and at pH 8.53. On the basis of this value, test chemical can be considered to be hydrophilic in nature.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -1.283
- at the temperature of:
- 27 °C
Additional information
Based on the available data in a key study from study report, the partition Coefficient n-octanol/water of test chemical was determined by Shake Flask Method. The study was performed at a temperature of 27°C and pH 8.53. The log Pow value was determined to be -1.283 at a temperature of 27°C and at pH 8.53.
Additional study from secondary source, authoritative and modelling databases indicates that the octanol water partition coefficient (log Pow) value of the test chemical was estimated to be -0.55.
Thus, based on the available information, the logPow value of the test chemical ranges from -1.283 to -0.55, respectively. On the basis of this value, test chemical can be considered to be hydrophilic in nature.
