The purpose of this study was the determination of the vapour pressure of the test item according to: European Commission Regulations (EC) No. 440/2008 and No. 761/2009, A.4. Vapour pressure: Dynamic method and OECD test guidelines, OECD 104 (2006) Vapour pressure OECD 113 (1981). The extrapolated vapour pressure values are at 20ºC is 3.37Pa; at 25ºC is 5.10Pa and at 50ºC is 33.7Pa.
