Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test item at 20 ºC was calculated from the average headspace concentration. The result was 0.016 Pa.
Therefore: Vapour pressure of Musk R1: 0.016 Pa at 20 ºC.
Executive summary:

The vapour pressure of the test material Musk R1 has been determined to be 0.016 Pa at 20 °C using the gas saturation method, designed to be compatible with Method A4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.
