Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study well documented and scientifically acceptable
- 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
- Analytical method:
- gas chromatography
- Type:
- log Pow
- Partition coefficient:
- 0.58
- Temp.:
- 25 °C
- pH:
- 10
- Conclusions:
- The LogPow value amounts to 0.58 (at 25 °C and pH 10).
- Executive summary:
The octanol-water partition coefficient of the substance Butyldiethanolamine was experimentally investigated according to standard methods (shake-flask method) equivalent to OECD Guideline 107 without GLP compliance (BASF AG, 1993). Three different concentrations were measured individually. Monitoring of substance concentrations by GC took place in both equilibrium phases. The LogPow value was determined to be 0.58 (at 25 °C and pH 10).
