Study Results

The concentrations of the different test solutions were calculated automatically using the equation of the calibration curve.

The external standard method was used. The n-octanol solubility was determined at 20 °C.

The n-octanol solubility of the test item Isooctadecanoic acid, potassium salt is 159.0 ± 0.493 g/L (standard deviation).

Conclusions:
The n-octanol solubility of the test item is 159.0 ± 0.493 g/L (standard deviation).
Executive summary:

The n-octanol solubility of the test item was determined according to OECD Guideline 105 – Flask method. n-Octanol was used instead of water. The n-octanol solubility of the test item is 159.0 ± 0.493 g/L (standard deviation). The external standard method was used. The n-octanol solubility was determined at 20 °C.

Description of key information

The n-octanol solubility of the test item is 159.0 ± 0.493 g/L (standard deviation).

Key value for chemical safety assessment

At the temperature of:
20 °C
Solubility in organic solvents at 20°C:
