Applicant's summary and conclusion

Conclusions:

The vapour pressure of the submission substance is estimated to be far below 0.000001 Pa.

Executive summary:

The vapour pressure of the submission substance was estimated by calculation in accordance with column 2 in Annex VII of Regulation (EC) No 1907/2006 by a calculation method recommended by the Guidance on Information Requirements and Chemical Safety Assessment (chapter R.7.1.5.3), MPBPVP of the EPI Suite (TM) software by the US Environmental Protection Agency (EPA, 2011).

The calculated vapour pressure value at 25°C is far below the chosen limit value of 0.000001 Pa.
