Reference
Endpoint:
partition coefficient
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline stydy with GLP
Qualifier:
according to
Guideline:
OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
Deviations:
no
GLP compliance:
yes
Type of method:
shake-flask method to: flask method
Partition coefficient type:
octanol-water
Type:
log Pow
Partition coefficient:
-1.7
Temp.:
23 °C
pH:
< 2

pH was not reported on study report; value indicated is a generic value for aqueous phase.3 concentrations have been tested; each of them has been doubled. Oxalic acid has been determined by HPLC method in both phases in order to avoid mass balance and less accurate results. All replicates fall within a +/-0.3 logKow

Conclusions:
Final value for log Kow is -1.70

Description of key information

Key value for chemical safety assessment

Log Kow (Log Pow):
-1.7
at the temperature of:
23 °C
