Additional information

Reliable experimental vapour pressure data is not available for Santicizer 278. An indicative value of 0.000000848 Pa at 20°C has been calculated using the QSAR MPBPVPWIN (USEPA, 2008). This value is supported by read-across from DEHP (ECB, 2008), DINP (ECB, 2003) and DIDP (ECB, 2003), which have a vapour pressure range of 0.000028 to 0.000034 Pa at 20°C.

Supporting company information is that the vapour pressures at 200 and 250 °C are 0.7 and 20 hPa respectively.
