Description of key information

Vapour pressure = 35 Pa at 25°C (interpolated)
Low volatility (based on ECETOC TRA criteria, <500 Pa).

Key value for chemical safety assessment

Vapour pressure:
35 Pa
at the temperature of:
25 °C

Additional information

Four reliable experimental study reports, following OECD/EU guideline, are presented. The magnitude of order was similar (35 to 151 Pa at 25°C, which is not considered to be significant regarding the measuring range of the property), indicating low volatility of the substance. However, three studies were conducted above ambient temperature, leading to distant extrapolation. Therefore the study conducted with the gas saturation method was prefered, and the interpolated result from the regression is retained.
