Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
- Principles of method if other than guideline:
- other (measured): equilibration: shake flask; analytical method: GC
- GLP compliance:
- not specified
- Type of method:
- shake-flask method to: flask method
- Partition coefficient type:
- octanol-water
- Specific details on test material used for the study:
- Supplier: Tokyo Kasei Co. (Tokyo)
- Analytical method:
- gas chromatography
- Key result
- Type:
- log Pow
- Partition coefficient:
- 1.38
- Temp.:
- 20 °C
- pH:
- ca. 7
- Remarks on result:
- other: The test originally was performed at room temperature and without a pH-value mentioned. Therefor we assumed a temperature of 20 °C. The test substance has no effect on the pH-value therefor it is assumed to be ca. pH: 7.0.
- Conclusions:
- Using a valid scientific method the partition coefficient of the substance was 1.38 at 20C.
- Executive summary:
Using a valid scientific method the partition coefficient of the substance was 1.38 at 20C.
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- 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)
- GLP compliance:
- no
- Type of method:
- shake-flask method to: flask method
- Partition coefficient type:
- octanol-water
- Specific details on test material used for the study:
- Methyl methacrylate from Ineos Acrylics, Batch No. Acrylics 98/15, purity: > 99 %
- Analytical method:
- high-performance liquid chromatography
- Type:
- log Pow
- Partition coefficient:
- 1.32
- Temp.:
- 20 °C
- pH:
- ca. 7
