Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 11 May 2010 to 7 January 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP study carried out in compliance with an internationally recognised guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
- GLP compliance:
- yes
- Type of method:
- shake-flask method to: flask method
- Partition coefficient type:
- octanol-water
- Analytical method:
- high-performance liquid chromatography
- Type:
- log Pow
- Partition coefficient:
- -0.3
- Temp.:
- 25 °C
- Remarks on result:
- other: pH not reported but study conducted under neutral (unbuffered) conditions. pH is not relevant as the substance has no ionisable groups.
- Conclusions:
- The octanol/water partition coefficient of the substance was determined by the shake flask method to be -0.30
Reference
Description of key information
The octanol/water partition coefficient of the substance was determined by the shake flask method to be -0.30 at 25 °C.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -0.3
- at the temperature of:
- 25 °C
Additional information
The octanol water partition coefficient was measured by Mitsui Chemicals, Inc., 2011, Report No.: ESD-2010 -016). Log Pow was determined according to OECD Method 107 and was considered reliable. DMI was found to have a Log Pow of -0.3 at 25°C.
