Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 24 December 2015 to 22 March 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient - Shake Flask Method)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EPA OPPTS 830.7550 (Partition Coefficient, n-octanol / H2O, Shake Flask Method)
- Principles of method if other than guideline:
- The Pow was calculated from the water solubility and the octanol solubility
- GLP compliance:
- yes
- Type of method:
- estimation method (solubility ratio)
- Partition coefficient type:
- octanol-water
- Analytical method:
- other: based on visual inspection of the octanol and water phase
- Key result
- Type:
- log Pow
- Partition coefficient:
- >= 0.22
- Temp.:
- 20 °C
- Remarks on result:
- other: no data on pH
- Key result
- Type:
- Pow
- Partition coefficient:
- >= 1.67
- Temp.:
- 20 °C
- Remarks on result:
- other: no data on pH
- Details on results:
- The resulting solutions were clear at 500, 760 and 1000 g/L were clear.
The calculation is based on the maximum observed solubility in water and octanol (600 and 1000 g/L respectively) in a worst case - Conclusions:
- The logPow is ≥ 0.22
- Executive summary:
In the shake flask method the octanol and water solubility of the substance were assessed separately. The logPow is based on a calculation using the water and octanol solubiliy. The logPow is ≥ 0.22.
