Applicant's summary and conclusion

Conclusions:
According to attached study report, the Vapour Pressure of Palmitoyl grapevine shoot extract is 3.41E10-3 Pa at 60°C.
Executive summary:

The vapour pressure of Palmitoyl grapevine shoot extract 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 or relevant weight loss.

As a calculation on base of the measured weight losses is not possible, the highest vapour pressure, derived from all measurements, is stated as limit value.

Vapour pressure at 60 °C: 3.41* 10-03 Pa
