Description of key information

Flammability: flammabile liquid ; experimentally determined flash-point 57 ±2 °C at 101.325 kPa

Key value for chemical safety assessment


Additional information

In accordance with section 1.2 of REACH Regulation (EC) No. 1907/2006 Annex XI the study of flammability does not need to be completed based on weight of available evidence. For liquids the primary value for ease of ignition is the flash point conducted using Method A9 ‘Flash Point Method’ of Council Regulation (EC) No 440/2008. The result of the Flash Point test is used to allocate a liquid substance into the appropriate flammability class. The substance has an experimentally determined flashpoint ≤ 60 °C and therefore under CLP Regulation (EC) 1272/2008 is to be considered a “flammable liquid” and assigned into the appropriate flammability category based on the flashpoint and initial boiling point. Substances with a flashpoint: 23 °C ≥ FP ≤ 60 °C are considered under flammable liquid: category 3.


Other measures of flammability include pyrophoricity and flammability on contact with water. These can be considered not a concern for the substance and testing waived if consideration of the structure and experience in handling and use show that no effects are envisaged. Such a screening procedure represents an intelligent testing strategy for flammability. If applied correctly then only liquid substances for which it is suspected will give a positive result in either the pyrophoric properties or flammability on contact with water tests need to be tested.


A review of the structure suggests that there are no chemical groups present that would imply pyrophoric properties or flammability on contact with water. A review of handling and used implies no pyrophoric properties or flammability on contact with water. Based on the absence of structural alerts and experience in handling and use negative results are predicted for pyrophoric properties and flammability of contact with water. Based on the known Flash Point of the substance it is considered not to be flammable. Therefore further testing for flammability is scientifically unjustified.

Justification for classification or non-classification

The substance does not meet classification criteria under EU Directive 67/548/EEC for flammability.

The substance does meet classification criteria under Regulation (EC) No 1272/2008 for flammabile liquid: category 3.
