Description of key information

Flash point (1,1,3,3-tetramethyldisiloxane): -27.3°C (ASTM D 3828-87), -25°C (closed-cup method)

Key value for chemical safety assessment

Additional information

Flash point values of -27.3°C and -25°C were determined for the substance using appropriate test methods. The results are considered to be reliable and were used as weight of evidence. In the other available data used as supporting studies, flash point values of <-20°C and ca. -26°C were determined for the substance using open cup and closed cup methods respectively. The supporting data are in good agreement with the key study.

Flash point values of -27.3°C and -25°C and a boiling point of 70.3°C indicate that the substance should be classified as a highly flammable liquid according to the criteria of EC Regulation 1272/2008.
