Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Reference
Endpoint:
partition coefficient
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Study period:
2018-02-19
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.8 (Partition Coefficient - Shake Flask Method)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EPA OPPTS 830.7550 (Partition Coefficient, n-octanol / H2O, Shake Flask Method)
Deviations:
no
GLP compliance:
no
Type of method:
estimation method (solubility ratio)
Partition coefficient type:
octanol-water
Key result
Type:
log Pow
Partition coefficient:
3
Temp.:
20 °C
Remarks on result:
not measured/tested
Remarks:
The log Pow was calculated based on the measured water solubility and n-octanol solubility of the test item because the test item is a surface active substance and the shake flask method is not appropriate.
Conclusions:
The n-octanol-water partition coefficient of Dimethylbis[2-[(1-oxohexadecyl)oxy]ethyl]ammonium
chloride at a temperature of approximately 20°°C was calculated to be:
log POW = 3.0
