Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP study without deficiencies
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient)
- Deviations:
- no
- Principles of method if other than guideline:
- The solubility of the test substance in n-octanol and in water is determined. The quotient of the n-octanol solubility and the water solubility is an estimation of the Pow. The estimation method can be applied if the shake flask method and HPLC method are not applicable.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: Estimation method
- Partition coefficient type:
- octanol-water
- Analytical method:
- other: The solubility of the test substance in n-octanol and in water is determined. The quotient of the n-octanol solubility and the water solubility is calculated directly.
- Type:
- log Pow
- Partition coefficient:
- > 6.7
- Temp.:
- 20 °C
- Remarks on result:
- other: pH not indicated
- Details on results:
- After the stirring period, a viscous orange/ brown solution was obtained without any undissolved material. From this, it was concluded that the n-octanol solubility of Barium bis( di C8-C10, branched, C9 rich, alkylnaphthalene sulphonate) at 20°C was > 1 × 10e+3 g/l.
- Conclusions:
- The Pow value of the test substance at 20°C was > 4.69 × 10e+6.
It corresponds with a log Pow value of > 6.7. - Executive summary:
The partition coefficient of Barium bis( di C8-C10, branched, C9 rich, alkylnaphthalene sulphonate) was determined by the estimation method following EU Method A.8 and OECD 107.
In the estimation method, the solubility of the test substance in n-octanol and in water is determined. The quotient of the n-octanol solubility and the water solubility is an estimation of the Pow. The estimation method can be applied if the shake flask method and HPLC method are not applicable.
n-Octanol solubility Test substance was stirred with n-octanol at a nominal concentration of 1051 g/l at 20.0 ± 0.3°C for 90 hours (4 days). After stirring, the test sample was checked visually for any undissolved material. Water solubility information on the water solubility of the test substance is given in section 4.8 Water solubility.001. The water solubility was 213 μg/l.
Calculation of Pow and Log Pow
Solubility in n-octanol > 1,000,000 mg/L
Solubility in water = 0.213 mg/L
Therefore the quotient of the n-octanol solubility and the water solubility (Pow) > 4.69+6 and the log10 of the Pow > 6.7.
Reference
Pow= Cn-octanol/ Cwater
Solubility in n-octanol > 1,000,000 mg/L
Solubility in water = 0.213 mg/L
The quotient of the n-octanol solubility and the water solubility (Pow) > 4.69e+6.
The log10 of the Pow > 6.7.
Description of key information
The Pow of the test substance at 20°C was > 4.69 × 10e+6.
This corresponds with a log Pow value of > 6.7.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 6.7
- at the temperature of:
