Description of key information

Flash point [octamethylcyclotetrasiloxane]: 51 - 55°C

Key value for chemical safety assessment

Flash point at 101 325 Pa:
51 °C

Additional information

Several measured reliable flash point values are available for the substance. Flash point values of 51 - 55°C using relevant closed-cup methods were determined for the substance. Also, an open-cup flash point value of 61°C was determined for the substance using relevant test method. The results are considered reliable even where no further information is available and are used as weight of evidence.

Variations in the flash point values may be caused by variations in purity of the test substance and the test method used.

A flash point of 51 - 55°C and a measured boiling point of 175°C, indicate that the substance should be classified as a flammable liquid according to the criteria of Regulation (EC) No.1272/2008.
