- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7550 (Partition Coefficient, n-octanol / H2O, Shake Flask Method)
- Version / remarks:
- August, 1996
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method
- Partition coefficient type:
- octanol-water
- Analytical method:
- other: Since the test item is surface active, the partition coefficient was calculated using the critical micelle concentration and the n-octanol solubility.
- Key result
- Type:
- log Pow
- Partition coefficient:
- >= 5
- Temp.:
- 20 °C
- pH:
- 7
- Details on results:
- the n-octanol solubility of the test item at 20.8 ± 0.2°C was ≥ 1000 g/L. The CMC of the test item was determined to be ≤ 10 mg/L.The Pow, calculated as the quotient of the n-octanol and CMC, is ≥ 1.0 ± 105. It corresponds with a log Pow value of ≥ 5.0.

Description of key information
Value is based on separate testing of solubilities in n-octanol and water, respectively.
Key value for chemical safety assessment
