Description of key information

Flash point: 45°C to 86°C

Key value for chemical safety assessment

Additional information

Several measured flash points are available. Those known to have been conducted according to international or national standard methods are considered reliable, even where no further information about the studies is available. The reliable values are 45, 51, 84 and 86°C.

Variations in the flash point values may be caused by variations in purity of the test substance and in the test method used. In particular, the presence of higher concentrations of methanol, a hydrolysis product of the substance, will result in lower flash points. The reliable values are taken as part of a weight of evidence approach. Individual companies will classify their products as appropriate.

Flash points of 45 and 51°C indicate the substance is flammable; flash points of 84 and 86°C indicate that the substance is not flammable.
