Results and discussion
Vapour pressure
- Remarks on result:
- not determinable
- Remarks:
- No vapour pressure was detected in two measurements. The lack of data was due to a blockage of the orifice.

Thermal Stability
In the temperature range of 40 – 50 °C a first endothermic exothermic effect can be observed. A second endothermic effect was detected in the temperature range of 180 – 210 °C. No exothermic effects were detected until the end of the measurement at 300 °C.
Measurement by the capillary method
A measurement with the capillary method was performed in the temperature range of room temperature to 120 °C with a heating rate of 10 K/min. Starting at a temperature of 75 °C the volume of the test item seemed to decrease. At 100 °C the test item began to form foam. At 110 °C the test item crawls up the capillary tube. The test is ended at 120 °C. Once the test item had cooled to room temperature it appeared the same as before the test.
In the test with the test tube no change of the test item was visible up to the final temperature of 90 °C. When the test item in the test tube is heated with a flame it turned dark grey and black where the flame was applied. The rest of the test item liquified and foamed. The highest measured temperature was 105 °C.
Effusion method: Vapour pressure balance
During the first measurement no vapour pressure was detected in the temperature range of 27 °C to 168 °C. During the second measurement no vapour pressure was detected in the temperature range of 27 °C to 87 °C. The lack of data was due to a blockage of the orifice.
Applicant's summary and conclusion
- Conclusions:
- No vapour pressure was detected in the temperature range of 27 °C to 168 °C. The lack of data was due to a blockage of the orifice.
- Executive summary:
Due to the properties of the test item Octadecanoic acid, reaction products with diethylenetriamine, di-Me sulfate-quaternized it was technically not possible to determine the vapour pressure via vapour pressure balance according to Regulation EC No. 440/2008 Method A.4. Vapour Pressure and OECD Test Guideline No. 104 (2006).
Two test runs were performed. Each time the test item was brought into the sample chamber of the equipment the evening before and left under vacuum (approximately 1E-04 Pa) at room temperature overnight to degas/dry the test item. The measurement was started once the required vacuum had been obtained (approximately 1E-04 Pa) and therefrigeration box had been cooled with liquid nitrogen. The series of measurements commenced at the lowest desired measuring temperature. When the orifice was opened for a certain time an increase of weight on the balance pan should have been measured. Taking into account the geometry of the vapour pressure balance, physical data of the test item and the evaporation rate Δm/Δt the vapour pressure can be calculated. As no increase of weight was observed the temperature was increased in small intervals until the maximum desired temperature value was reached. At no temperature an increase of weight on the balance pan was observed.
When the apparatus was opened after the measurement it became apparent that in both test runs the test item has been blocking the orifice. Therefore, evaporating test item could not leave the sample chamber. It is possible that the test item splattered when vacuum was applied and eventually blocked the orifice. That is why the vacuum was applied more carefully during the second test run, but it resulted again in a blockage of the orifice. At the end of both tests the test item had a wax-like consistency.
