Key result
Type:
log Pow
Partition coefficient:
> 3
Temp.:
20 °C
Remarks on result:
other: pH is not specified
Type:
Pow
Partition coefficient:
> 890
Temp.:
20 °C
Remarks on result:
other: pH is not specified
Conclusions:
The Pow of the substance at 20°C was estimated to be > 890 (log Pow > 3.0).


Executive summary:

Because the substance is surface active both the HPLC method and the shake-flask method are not applicable. The log Pow of the substance was therefore estimated from the ratio n-octanol solubility and critical micelle concentration. GLP study according to EC A.8, OECD 107 and OPPTS 830.7550. The Pow of the substance at 20°C was estimated to be > 890 (log Pow > 3.0).

Description of key information
