Description of key information

Flammability [dodecamethylcyclohexasiloxane]: not flammable

Key value for chemical safety assessment

non flammable

Additional information

In accordance with Section 1 of REACH Annex XI, the study does not need to be conducted as the flammability of liquids is assessed by reference to the flash point.

There is no indication on the basis of structure and experience in handling and use that the substance is flammable in contact with air or water.

A lower flammable limit of 0.43 Vol. % and an upper flammable limit of 17.22 Vol. % at 1010.58 - 1029.24 hPa was determined for the substance in accordance with ASTM E-681.

Justification for classification or non-classification

The substance is not classified for flammability in accordance with Regulation (EC) No. 1272/2008. This is on the basis of a measured flash point of 91°C at 1013 hPa and a boiling point of 245°C at 1013 hPa.
