Validity criteria:

COPPER DIBUTYLDITHIO CARBAMATE concentration did not exceed 0.01M in each phase.

The six log Pow values obtained are within the range of ± 0.3 units

Conclusions:
The Partition Coefficient of COPPER DIBUTYLDITHIO CARBAMATE is 4.73
Executive summary:

The Partition Coefficient of the test item COPPER DIBUTYLDITHIO CARBAMATE was determined according to the OECD 107 guideline. The value of 4.73 was calculated from six determinations of Kow and 3 ratios of Octanol/Water (at 22°C and pH between 7.2 and 7.5.
