20 °C

Additional information

A literature search was conducted. The available data were evaluated in a weight of evidence approach. All relevant literature values were obtained in REAXYS database. Reaxys is a database for the retrieval of chemistry information and data from published literature including journals and patents. The information includes chemical compounds, chemical reactions, chemical properties, related bibliographic data, and substance data with synthesis planning information, as well as experimental procedures from selected journals and patents. Reaxys provide experimentally measured data covering chemical reactions, physical, chemical or pharmacological properties. The Reaxys database is regarded as reliable and was therefore taken into account for this weight of evidence approach. Five independent literature values were reported. Timmermans and Hennaut-Roland (1935) report the dynamic viscosity to be 2.22 mPa.s at 20 °C. Furthermore Yaw-Wen Sheu, Chein-Hsiun Tu (2006) report the dynamic viscosity to be 1.971 mPa.s at 25 °C, García et al (2004) report the dynamic viscosity to be 1.973 mPa.s at 25 °C and Mumford and Phillips (1950) report the dynamic viscosity to be 1.99 mPa.s at 25 °C. The dynamic viscosity is temperature dependent and decrease with an increase of temperature. All values reported at 25 °C were in the same range and support the dynamic viscosity at 20 °C. Thus, the value at 20 °C was regarded as reliable and was therefore chosen as key value for chemical safety assessment.
