Description of key information

The calculated vapour pressure of Santicizer 261A is 0.000117 Pa at 20˚C.

Key value for chemical safety assessment

Additional information

Reliable experimental vapour pressure data is not available for Santicizer 261A. An indicative value of 0.000117 Pa at 20°C has been calculated using the QSAR MPBPVPWIN (USEPA, 2008). Santicizer 261A is in the domain of this QSAR. 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. This is supported by company data which reports the vapour pressure to be 0.7 and 13 hPa at 200 and 250°C respectively.
