- Remarks on result:
- no reaction with water observed
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The test item is considered as Not flammable in contact with water.
- Executive summary:
The flammability of the substance in contact with water was tested under GLP, according to EU A.12 guideline.
Step 1 (dish containing water), 2 (floated filter paper) and 4 (water dropped into a closed flask, and volume of gas evolved measured) were performed. No gas evolution and no spontaneous ignition was observed in all steps.

- - Storage condition of test material: fridge (2-8°C); away from light and humidity
- Key result
- Test procedure:
- ignition time on contact with air
- Remarks on result:
- no ignition within 5 minutes
- Key result
- Test procedure:
- effect on filter paper
- Remarks on result:
- no ignition within 5 minutes
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The test item is considered as Not pyrophoric.
- Executive summary:
The pyrophoric properties of the substance were tested under GLP, according to EU A.13 guideline.
No spontaneous ignition was observed, whether from the substance poured into a cup with diatomaceous earth, or from soaking a filter paper.
- 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
Referenceopen allclose all
| Step | Gas evolution | Ignition | Gas volume (7 hours) |
| 1 | no | no | - |
| 2 | no | no | - |
| 4 | no | no | 0 |
The observations were the same for each of the three replicates of step 4.
No ignition was observed in the 6 repetitions of each experiment.
Description of key information
Flash point = 128°C (experimental)
Not flammable if contact with air or water (experimental).
No self-heating anticipated for liquids (waived).
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
As the substance is a liquid, the relevant test for flammable properties is the Flash Point measurement.
A reliable experimental study is presented under point 4.11.
Fully reliable experimental studies, conducted according to recognized EC methods and under GLP, are available also for pyrophoric properties and flammability in contact with water. Therefore, they are considered as key studies.
As a liquid, no self-heating is anticipated, study was deemed unnecessary.
Justification for classification or non-classification
According to Regulation (EC) No.1272/2008 (CLP) criteria, the measured flash point is above the threshold value of 60°C, therefore the substance is NOT considered as a flammable liquid.
According to UN Globally Harmonised System (GHS) criteria, the measured flash point is above the threshold value of 93°C, therefore the substance is NOT considered as a flammable liquid.
According to CLP and GHS criteria, since no spontaneous ignition was observed in contact with air or water, the substance is NOT considered as a pyrophoric liquid, or a substance which can emit flammable gas.
