Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 19.03.2015 - 19.06.2015
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Due to the complex composition of the sample the partition coefficient could not be determined by the methods layed down by Regulation (EC) 440/2008, EU-method A.23. The difference of concentrations in water and n-octanol is small. Interference from microemulsions can be neglected. The partition coefficient has been calculated by means of absorbance at 230 nm.
- GLP compliance:
- no
- Type of method:
- calculation method (fragments)
- Partition coefficient type:
- octanol-water
- Key result
- Type:
- Pow
- Partition coefficient:
- 0.118
- Temp.:
- 20 °C
- pH:
- 8.48
- Conclusions:
- Sulfonic acids, shale-oil, sodium salts has a partition coefficient of 0.118 (20°C). The partition coefficient has been calculated by means of absorbance at 230 nm.
- Executive summary:
Sulfonic acids, shale-oil, sodium salts has a partition coefficient of 0.118 (20°C). The partition coefficient has been calculated by means of absorbance at 230 nm.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
