Any other information on results incl. tables

First measurement:

Mass test item: 4.70 mg

Mass crucible before measurement: 49.78 mg

Mass crucible after measurement: 46.05 mg

Observations:

A small amount of the test item was found on the out- side of the crucible. This test material was discol- oured to orange-yellow and had escaped through the perforation.

Second measurement:

Mass test item: 4.46 mg

Mass crucible before measurement: 49.18 mg

Mass crucible after measurement: 45.76 mg

Observations:

A small amount of the test item was found on the out- side of the crucible. The material was discoloured to orange-yellow and had escaped through the perforation. When the crucible was opened, no test item was visible in the crucible, but the inside of the crucible was slightly discoloured to orange-yellow.

Interpretation of the measurements:

Two DSC measurements were performed. In both measurements an endothermic event was visible. Since the event is not a single peak, it could be caused by superheating of the test item, which would also explain the contamination of the crucible after performance.

Applicant's summary and conclusion

Conclusions:
The boiling point of the Oligomerisation product obtained by plasma treatment of vegetable oil mono- and polyunsaturated C16-C22 triglycerides could not be determined. The test item was found to become superheated during the DSC experiment as of a temperature of ca. 402°C, but no boiling was observed.
Executive summary:

The boiling point of the Oligomerisation product obtained by plasma treatment of vegetable oil mono- and polyunsaturated C16-C22 triglycerides was examined in accordance with OECD guideline 103 and EU guideline A.2.

During the security pre-test, an endothermic effect was observed, beginning at 402°C. However, since the event is not a single peak, it is considered to be caused by superheating of the test item. As a consequence, no boiling point could be determined under the given test circumstances.
