Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Flammability (hexamethyldisiloxane): highly flammable
Key value for chemical safety assessment
- Flammability:
- highly flammable
Additional information
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 the use that the substance is flammable in contact with air or water.
Therefore, in accordance with Section 2 of REACH Annex XI, the flammability study does not need to be conducted.
Lower flammability limits of between 1.0 – 1.5 %v/v and upper flammability limits of 14.65 – 38.0 %v/v were reported in secondary literature (company product literature / MSDS). The original references were not available for review and no further information is available.
Justification for classification or non-classification
The substance is classified R11 (Highly Flammable) according to Directive 67/548/EEC and Flammable Liquid Category 2 (H225: Highly flammable liquid and vapour) according to EC Regulation 1272/2008. This is on the basis of a flash point of -6°C and a boiling point of 100.5°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
