- 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.
