Description of key information

A flash point was measured for the high trans (cis/trans: 10/90) and the high cis quality (cis/trans: 85/15), respectively. The test material is not classified as flammable for all isomers ratio.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
150 °C

Additional information


The flash point was performed on two different qualities of the substance with the closed-cup method using the ASTM D6450-99 standard method and the Method A9 of 440/2008/EEC. Results were 150 +/- 0.2°C and 156 +/- 2°C for cis:trans ratio of 10:90 and 80:20, respectively. Therefore, the isomer composition has no significant influence on the flammability hazard. Classification is discussed under point 4.13.
