Table 1: Summary of vapour pressure data

 Run  Log10 [Vp(25 °C)]
 1  -0.771
 2  -0.804
 3  -0.890
 Mean  -0.822
 Vapour pressure  0.151 Pa

A total of ten runs were completed for the main sequence. Equilibrium with regard to vapor pressure was assessed to have been reached over the first three runs. Thus runs one to three have been used to calculate the definitive vapor pressure value for the test item.

Conclusions:
Under the conditions of the study, the vapour pressure of (Z)-3-hexenyl salicylate was determined to be 0.15 Pa at 25 °C using the vapour pressure balance method.
Executive summary:

In a GLP-compliant vapour pressure study conducted in line with EU Method A.4, the vapour pressure of (Z)-3-hexenyl salicylate was determined using the vapour pressure balance method. The vapour pressure of the substance was determined to be 0.15 Pa at 25 °C.
