Reference
The measurements were made at a pH 6 and at an initial concentration of 22 mg/L in the water phase (about 1% of the critical micelle concentration (CMC) in water) and at 25°C. The partition coefficient value was determined from the weighed average of the concentrations of the main components in the product listed in the table below.
| Substance | Log Pow |
N-(3-(Tridecyloxy) propyl)-1 ,3-propane diamine, branchedmonoacetate/ N-(3-(Tridecyloxy) propyl)-1 ,3-propane diamine, branched(technical) |
