- Conclusions:
- The log Kow of Esterification products of triglycerides C18 unsaturated with triethanolamine, dimethyl sulfate quaternized was determined to be 3.69 by measuring the individual solubilities in n-octanol and water.
- Executive summary:
The log Kow of Esterification products of triglycerides C18 unsaturated with triethanolamine, dimethyl sulfate quaternized was determined by measuring the individual solubilities in n-octanol and water.
The Critical Micelle Concentration of Esterification products of triglycerides C18 unsaturated with triethanolamine, dimethyl sulfate quaternized was determined by measuring the surface tension of a range of aqueous sample solutions of differing concentration accodring to Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
The solubility in n-Octanol was determiend to be >250 g/L of solution at 20.0 ± 0.5 °C by visual observation, based on CIPAC method MT 181.
Based on these results, the log Kow was calculated to be 3.69.

Additional information
The log Kow of Esterification products of triglycerides C18 unsaturated with triethanolamine, dimethyl sulfate quaternized was determined by measuring the individual solubilities in n-octanol and water.
The Critical Micelle Concentration of Esterification products of triglycerides C18 unsaturated with triethanolamine, dimethyl sulfate quaternized was determined by measuring the surface tension of a range of aqueous sample solutions of differing concentration accodring to Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The CMC was determined to be 51.3 mg/L at 20.0 ± 0.5 °C.
The solubility in n-Octanol was determiend to be >250 g/L of solution at 20.0 ± 0.5 °C by visual observation, based on CIPAC method MT 181.
Based on these results, the log Kow was calculated to be 3.69.
