Key result
Type:
log Pow
Partition coefficient:
1.01
Remarks on result:
other: log Kow (KOWWIN v1.68 estimate). No data is provided on temperature and pH.

KOWWIN v1.68 predicted that the substance has a log Pow = 1.01

Conclusions:
The Log Pow of the test item is 1.01 (EPISUITE, KOWWIN v1.68).
Executive summary:

According to EPISUITE model KOWWIN v1.68, the Log Pow of the test item is 1.01.

Description of key information
