- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient)
- Qualifier:
- according to guideline
- Guideline:

- Partition coefficient type:
- octanol-water
- Analytical method:
- gas chromatography
- Type:
- log Pow
- Partition coefficient:
- 2.01
- Temp.:
- 20 °C
- Remarks on result:
- other: log Kow at temperature between 20-25°C
- Type:
- Pow
- Partition coefficient:
- 102.4
- Temp.:
- 20 °C
- Remarks on result:
- other: Kow at temperature between 20-25°C
- Conclusions:
- Partition coefficient of the substance was determined in water. The ratio of n-Octanol: water used in the study was 1:1, 1:2, and 2:1. N-n-butylbenzenesulphonamide (Proviplast 024) was determined to have a mean Kow of 102.4 and log Kow of 2.01 +/- 0.3 at less than 25°C and greater than 20 °C in water.
- Executive summary:
The partition coefficient of the substance was determined in water according to OECD 107, shake flask method. The ratio of n-Octanol: water used in the study was 1:1, 1:2, and 2:1. The substance, N-n-butylbenzenesulphonamide (Proviplast 024), was determined to have a mean Kow of 102.4 and log Kow of 2.01 +/- 0.3 at less than 25°C and greater than 20 °C in water.
