- Remarks:
- The mean vapour pressure determined from run 1 and 2 for the test item.
- Conclusions:
- The vapour pressure determined of the test item, Triglycerides, C16 and C18 (unsaturated), was calculated to be 0.008 Pa at 25°C.
- Executive summary:
A study to determine vapour pressure of the test item, triglycerides, C16 and C18 (unsaturated), was conducted according to OECD 104 and EC A.4 guidelines. The vapour pressure was determined by the effusion method using isothermal thermogravimetry analysis. The mean vapour pressure for the test item, triglycerides, C16 and C18 (unsaturated), was calculated to be 0.008 Pa at 25°C.
The study was conducted according to standard guidelines and is GLP-compliant and therefore is considered as reliable without restrictions.
Reference
The results from runs 1 and 3, which were performed using a fresh sample in each case, were reported as the vapour pressure decreased when the same sample was used multiple times. This is because the test item is a multicomponent mixture, and as multiple measurements were made, the more volatile components would have a tendency to evaporate first.
A summary of results for run 1 and 3 is shown in the table below:

Additional information
The vapour pressure of the test item was determined in a study following OECD 104 and EC A.4 guidelines, by the effusion method using isothermal thermogravimetry analysis (Dunning 2019). The study is a GLP compliant, guideline experimental study and is fully acceptable for assessment of this endpoint.
