Vapour pressure estimation of the submission substance
As the calculated vapour pressure of its components is far below the chosen limit value of 0.000001 Pa, the vapour pressure of the submission substance is also estimated to be far below 0.000001 Pa.
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 submission substance is an about half-and-half mixture of two components. Calculation of the vapour pressure of a mixture is not applicable in MPBPVP, therefore vapour pressure values for the components were estimated by calculation.
The calculated vapour pressureof the components at 25°C is far below the chosen limit value of 0.000001 Pa, therefore the vapour pressure of the submission substance is also estimated to be far below 0.000001 Pa.
