Remarks:
Due to the high content of volatile impurities, the vapour pressure is overestimated. Therefore, the vapour pressure was determined in a second experiment using the dynamic method which is more appropriate.

Conclusions:
The vapour pressure of 1,3-BDDMA is determined to be ca. 1.1 hPa at 20°C using the static method (determined according to OECD guideline 104, adopted 27 July 1995, and EU Method A.4, Council Regulation (EC) No 440/2008 of 30 May 2008, static method). Due to the high content of volatile impurities, the dynamic method is more appropriate and the result obtained with this method was used for exposure assessment.

Description of key information

The vapour pressure of 1,3-BDDMA is determined to be < 0.1 hPa at 20°C using the dynamic method

(determined according to OECD guideline 104, adopted 27 July 1995, and EU Method A.4, Council Regulation (EC) No 440/2008 of 30 May 2008, dynamic method).

Due to the high content of volatile impurities, the dynamic method is more appropriate and the result obtained with this method was used for exposure assessment.
