Description of key information

Additional information

Data on physical properties were obtained from a number of secondary sources. The data in these secondary sources are based on a critical evaluation of peer-reviewed data and the selected values are considered to be reliable and representative of the property under investigation. Information in the review process was documented in the introduction of the source. The use of Klimisch codes (Klimisch et al., 1997), was extended to these secondary sources and a reliability code of (2)valid with restrictions was assigned when using the authoritative secondary source. Proprietary data has also been used and this has been reviewed and assessed for reliability using klimisch codes. Where proprietary data has been considered reliable it has been given a reliability code of (2)valid with restrictions and has been used in the assessment.

The boiling point for n-hexane is 65 -72°C based on the data range agreed by the consortium and the flashpoint is <-20°C. According to the CLP legislation (2008) a substace with flash point <23°C and a boiling point >35°C is classified as a Category 2 flammable liquid.
