Results and discussion
Vapour pressure
- Temp.:
- 20 °C
- Vapour pressure:
- 140 Pa
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 140 Pa.
Therefore: Vapour pressure of Menthene para: 140 Pa at 20 ºC. - Executive summary:
The vapour pressure of the test material Menthene para has been determined to be 140 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.
