EC number: 943-493-6
CAS number: 72681-01-7
Flammability: non-flammable liquid ; experimentally
determined flash-point > 60 °C at 101.325 kPa.
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. The substance has an
experimentally determined flashpoint > 60 °C and therefore under CLP
Regulation (EC) 1272/2008 cannot be considered a “flammable liquid”.
Therefore testing for flammability is scientifically unjustified.
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.
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.
