The vapour pressure of Oligomerisation product obtained by plasma treatment of vegetable oil mono- and polyunsaturated C16-C22 triglycerides was determined according to OECD 104 resp. EU A.4 using the effusion method (weight loss).
Vapour pressure was examined at nine different temperatures. No temperatures could be evaluated as they showed no reproducible weight loss (RSD above 30% at each temperature step).
Therefore, a calculation on base of the measured weight losses is not possible, and no vapour pressure could be stated.
Applicant's summary and conclusion
- Executive summary:
The vapour pressure of the test item "Oligomerisation product obtained by plasma treatment of vegetable oil mono- and polyunsaturated C16-C22 triglycerides" was determined at nine different temperatures (30, 45, 60, 75, 90, 105, 120, 135 and 150 °C) according to OECD 104 resp. EU A.4 using the effusion method (weight loss). All experiments 1 - 9 (nominal temperature 30 - 150 °C) showed no reproducible weight loss. When visible contaminations, caused by explosive evaporation of the test item, were observed, the cells were meticulously cleaned and weighed. This weight was used as initial weight for the subsequent measurements. To avoid bias, these measurements were not used for calculations.
A calculation on base of the measured weight losses is not possible, and no vapour pressure could be stated. This was caused due to the behaviour and composition of the test item (UVCB substance). The test item is an UVCB substance with different components, which have different vapour pressures. Therefore, it is possible that these components evaporate at different temperatures with a different intensity. This could have caused the non reproducible weight loss.
