Applicant's summary and conclusion
- Executive summary:
The vapour pressure of JASMONYL LGwas determined following EU A.4 using the effusion method (weight loss).
Vapour pressure was examined atfive different temperatures.
For the test itemJASMONYL LG, the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 7.47Pa
Vapour pressure at 25 °C: 8.32Pa
