Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test item Tocopherols Concentrate was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C, according to Regulation EC No. 440/2008 Method A.4. Vapour Pressure and OECD Test Guideline No. 104 (2006): 1.1 × 10-6 Pa, 2.3 × 10-6 Pa and 5.7 × 10-5 Pa, respectively.
