Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Justification for data waiving:

Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
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.

Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture

Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACH Regulation (EC) No. 1907/2006 Annex XI, the does not need to be performed as based on assessment of the chemical structure flammability on contact with water properties are not to be expected and this is supported by experience in handling and use for the substance. According to ECHA Guidance on Information Requirements and Chemical Safety Assessment (Chapter R.7a: Endpoint Specific Guidance, R.7.1.10.8, July 2017), flammability on contact with water testing is scientifically unjustified.
Endpoint:
pyrophoric liquids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

According to ECHA Guidance on Information Requirements and Chemical Safety Assessment (Chapter R.7a: Endpoint Specific Guidance, R.7.1.10.5, July 2017), pyrophoricity testing is scientifically unjustified.

Description of key information

Flammability: non-flammable liquid ; experimentally determined flash-point > 60 °C  at 101.325 kPa.

Key value for chemical safety assessment

Flammability:
non flammable
