- Endpoint:
- self-heating substances / mixtures
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is a liquid
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to ECHA Guidance on the Application of the CLP Criteria (v5.0, July 2017, §2.11.4.2.), the phenomenon of self-heating generally applies only to solids. The surface of liquids is not large enough for reaction with air and the test method (UN N4) is not applicable to liquids. Therefore liquids, unless adsorbed, are not classified as self-heating.
Moreover, the chemical structure does not contain metals, which are typically self-heating substances. - Reason / purpose for cross-reference:
- data waiving: supporting information
- 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
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to REACh Annex XI / section 1, study for flammability if contact with water is deemed unnecessary, based on the experience in handling, testing and use of the substance.
Moreover, the chemical structure does not fall into critical categories described in the ECHA Guidance on the Application of the CLP Criteria (v5.0, July 2017, §2.12.7.1.) or in the Bretherick’s Handbook of Reactive Chemical Hazards (6th Edition, 1999, Volume 2, water-reactive compounds) (e.g. no acid anhydrides, halides, oxides, alkali metals, alkyl aluminium derivatives, alkyl metals, complex or metal hydrides, metal phosphides, certain metal powders...). - Endpoint:
- flammable liquids: obsolete as covered by section 'Flash point'
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is a liquid
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to REACh Annex XI / section 2, flammability study UN N1 relevant for classification criteria under IUCLID Section 4.13 does not apply to liquids. Please refer to Flash Point under IUCLID section 4.11. - Reason / purpose for cross-reference:
- reference to other study
- 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

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:
- not classified
Additional information
According to REACh Annex XI / section 2, flammability study UN N1 relevant for classification criteria under IUCLID Section 4.13 does not apply to liquids. Therefore testing for flammability is technically not feasible, and can be waived.
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.
As a liquid, no self-heating anticipated either.

Moreover, the substance can be use as flame retardant, which supports the low potential for flammable properties.
Justification for classification or non-classification
The substance does not meet the criteria for classification in accordance with Regulation (EC) No 1272/2008 (CLP): The substance has an experimentally determined flash point > 60 °C and therefore cannot be considered a “flammable liquid”.
