Key result
Type:
log Pow
Partition coefficient:
3.9
Temp.:
25 °C
Remarks on result:
other: pH not provided in the study report
Details on results:
The pH is assessed not to be critical based on the absence of acidic and basic structural features of BENZOIN RESIN and in its molecular structure.
Conclusions:
The partition coefficient of BENZOIN RESIN has been determined as log P = 1.3-3.9 at 25°C in a study equivalent to OECD Guideline 117 (HPLC method) in a reliable non-GLP study.
Executive summary:

The partition coefficient of BENZOIN RESIN has been determined as log P = 1.3-3.9 at 25°C in a study equivalent to OECD Guideline 117 (HPLC Method).

Description of key information

The partition coefficient of BENZOIN RESIN has been determined as log P = 1.3-3.9 at 25°C in a study equivalent to OECD Guideline 117 (HPLC Method). As the individual log Kow values cant be assigned to the different constituents of this UVCB it was decided to take the average as key value.
