Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- -1.76
- Temp.:
- 21 °C
- Details on results:
- Approximate solubility in n-octanol: 10.8% w/w
Approximate solubility in water: 75.3% w/w
Approximate Pow: 0.143
Log10 Pow: -0.845
Any other information on results incl. tables
Substances having a log10 Pow of greater than 3 are regarded as having the potential to bioaccumulate in the environment. This test material will not bioaccumulate in the environment as the log10 Pow is less than 3.
Applicant's summary and conclusion
