- octanol-water
- Key result
- Type:
- log Pow
- Partition coefficient:
- 17.09
- Remarks on result:
- other: no additional details mentioned
- Conclusions:
- The experimental logPow of test chemical was 17.09
- Executive summary:
The experimental logPow of test chemical was 17.09. Test chemical can be considered hydrophobic in nature, which also supported by its very low solubility in water.

Description of key information
The experimental logPow value of test chemical was 17.09. On the basis of this value test chemical can be considered highly hydrophobic in nature, which also supported by its very low solubility in water.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 17.09
Additional information
The experimental logPow value of test chemical was determined to be 17.09 dimensionless. In next study the KOWWIN v1.68 was used to estimate the octanol water partition coefficient of substance.. The estimated logPow of test chemical was 16.58.
The experimental and estimated values indicate that substance is highly hydrophobic in nature, which is also supported by its very low solubility in water.
