Additional information
Key study
The vapour pressure of the test item was assessed by dynamic and gas saturation method according to OECD guideline 104 and in compliance with GLP principles (BASF SE, 2016). In the temperature range used for vapour pressure measurements the test item was liquid. The vapor pressure at 10, 25 and 50 °C were calculated with regression equation of the measured vapour pressure. In result, the vapour pressure of the test item was determined to be 0.00252 hPa at 20 °C, 0.00459 hPa at 25 °C and 0.0597 hPa at 50 °C.
Supporting study
In a supporting study (BASF AG, 2002) the vapour pressure of the test item was determined using a dynamic method based on the principle of a Cottrell pump. The vapour pressure was determined to be 0.2 hPa at 20 °C and 1.0 hPa at 50 °C respectively. In addition the Hommel Handbook of dangerous goods (Hommel, 2014) report the vapour pressure to be 0.2 hPa at 20 °C.
Based on the most current and reliable result (BASF SE, 2016), the vapor pressure of the test item is considered to be 0.00252 hPa at 20 °C.
