- Unnamed
- Year:
- 2 020
Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- During the test for water solubility the solubility of the test item in several organic solvents was tested for analytical reasons. These tests were no quantitative solubilitity tests, but sufficient to
give a minimum solubility of the substance in the respective solvent. The solubility in water was measured in a guideline study. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: Mixing of the substance in 1-octanol for 1 min. in an ultrasonic bath.
- Partition coefficient type:
- octanol-water
Test material
- Reference substance name:
- Gawarol
- IUPAC Name:
- Gawarol
- Test material form:
- solid: crystalline
Constituent 1
Study design
- Analytical method:
- high-performance liquid chromatography
- other: visual determination for solubility in 1-octanol
Results and discussion
Partition coefficient
- Key result
- Type:
- log Pow
- Partition coefficient:
- > 5.63
- Temp.:
- 20 °C
- pH:
- ca. 6 - ca. 7
- Remarks on result:
- other: Calculated from Solubility in 1-octanol and water
Applicant's summary and conclusion
- Conclusions:
- The Log Pow was calculated from experimental Limit values of the water solubility and solubility in 1-octanol. Because the solubility of the substance in 1-octanol is with high probability much higher then the used
quantity in the limit test, the Log Pow is most likely much higher then the minimum value > 5.63.
