- Details on results:
- The device used was a special flask identical to the model described in the Annex 2 of the OECD123 Guideline. It allows sampling of the octanol phase through the upper part and sampling of the water phase by the valve at the lower part.
The two solvents are mutually saturated at the temperature of the experiment (25°C ± 0.5°C) by contacting 1.8 L of ultrapure water and 1.8 L of 1-Octanol. Slow-stirring of the mixture was performed during 4 days at 25 °C.
The critical micellar concentration (CMC) of the test item determined in another study is 1.31 g/L. Thus, according to the OECD 123 Guideline, the Pow determination was performed using a solution at 0.655 g/L of 1,3-Propanediamine,N-tallow-,diacetate in octanol saturated ultrapure water (that is half the CMC).
This solution was prepared by dissolution of 982 mg of the test item into 1.5 L of octanol saturated ultrapure water. The solution was then slowly stirred during 45 min., avoiding to create any foam or emulsion. The final pH of this stock solution was 5.63, thus it was not necessary to adjust it.
For each of the following experiments, two replicates were used.
For the first experiment, the volumic ratio octanol/water was 0.5: 165 mL of octanol and 330 mL of the water stock solution. For the second experiment, the volumic ratio octanol/water was 1: 250 mL of octanol and 250 mL of the water stock solution. For the third experiment, the volumic ratio octanol/water was 2: 330 mL of octanol and 165 mL of the water stock solution. Speed of stirring was adjusted in order to obtain a vortex of approximately 2 cm. Temperature was 25°C ± 0.5°C. Samples of each phase for each experiment were taken along time and given to analysis for determination of the concentration of the test item. - Conclusions:
- The partition coefficient for Amines, N-(C16-18 and C18-unsatd. alkyl)trimethylenedi-, diacetates has been determined according to OECD 123 and following GLP. In the test conditions ( t° = 25°C), Log Pow is determined to 0.49.
- Executive summary:
The objective of this study was to determine the Partition Coefficient of the test item 1,3-Propanediamine,N-tallow-,diacetate applying the procedure described in the OECD Guideline 123 Partition Coefficient (1-Octanol/water), Slow-Stirring Method.
In comparison with the OECD 107 method, the slow-stirring avoid the formation of microdroplets of either octanol phase in water or water phase in octanol. The slow stirring method in theory is the best for surface active substance, but still not demonstrated to be perfect according REACH guidance document R7a (v6 July 2017 page 79).
During the test, the temperature was 25°C and the pH value was 5.63. The partition coefficient for Amines, N-(C16-18 and C18-unsatd. alkyl)trimethylenedi-, diacetates has been determined according to OECD 123 and following GLP. In the test conditions at 25°C, the average value of Log P o/w for 1,3-Propanediamine,N-tallow-,diacetate is 0.49.

- Executive summary:
A determination of the partition coefficient for N-oleyl-1,3-diaminopropane CAS no 7173-62-8, has been performed by using the slow stirring method according to OECD Guidelines for the Testing of Chemicals, ‘Partition coefficient (1-octanol/water): Slow stirring method’, no 123.
The measurements were made at neutral conditions (pH=6.8) and at an initial concentration of 38 mg/L in the water phase (ca 50% of the critical micelle concentration (CMC). The partition coefficient value was determined from the sum of the concentrations of the main components in the product: Diamines of C14, C16, C16’, C18’ and C18’’.
