Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2007
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Principles of method if other than guideline:
- Estimation method based on the ratio of the solubility of the material in water and octanol.
The analytical method for the determination is in agreement with the method that was agreed upon at the "Analytical Experts Meeting" of ETAD (Basel) on January 12, 2005. - GLP compliance:
- no
- Type of method:
- estimation method (solubility ratio)
- Partition coefficient type:
- octanol-water
- Analytical method:
- photometric method
- Key result
- Type:
- log Pow
- Partition coefficient:
- 0.31
- Temp.:
- 25 °C
- Remarks on result:
- other: pH value not available
- Details on results:
- The resulting clear solution was measured by UV-vis spectrometry and the absorption was determined at A448 nm.
The determination was repeated for three times.
The solubility of test item in water is 2.9 µg/L
The solubility of test item in n-octanol is 5.9 µg/L - Conclusions:
- The partition coefficeint of test substance was estimated to be logPow= 0.31 at 25°C based on individual solubilities.
Reference
Description of key information
Estimated based on solubility ratio:
logPow= 0.31 at 25 °C
Key value for chemical safety assessment
Additional information
Bulk form:
The logPow value was estimated based on individual solubilities in octanol and water.
The analytical method for the determination is in agreement with the method that was agreed upon at the "Analytical Experts Meeting" of ETAD (Basel) on January 12, 2005.
