Description of key information

Flammability (decemethyltetrasiloxane): flammable liquid

Key value for chemical safety assessment

Flammability:
flammable

Additional information

The flammability study is not required for liquids as flammability is assessed on the basis of flash point.

 

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

 

Therefore, in accordance with Section 1 of REACH Annex XI, there is no need to conduct further flammability testing.

Justification for classification or non-classification

The substance is classified as Flammable Liquid Category 3 (H226: Flammable liquid and vapour) according to EC Regulation 1272/2008. This is on the basis of flash point of 62 - 63°C and a boiling point of 194°C.
