Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- no

- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15.06.2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Qualifier:
- according to guideline

- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Hess. Ministerium für Umwelt, Energie, Landwirtschaft und Verbraucherschutz, Mainzer Straße 80, D65189 Wiesbaden
- Interpretation of results:
- not classified based on GHS criteria
- 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 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
- Endpoint:
- pyrophoric solids
- 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
- Endpoint:
- self-heating substances / mixtures
- 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 completely molten at 160°C
Referenceopen allclose all
In all the tests, the test substance started to melt. It was thereby classified as not highly flamable within the definition of the Directive 84/449/EEC.
Individual results
Preliminary test
The test item was a solidified melt. Therefore it was ground in a mortar before the measurement. The test item could not be ignited with a flame. The test item melted. The main test had not to be performed.
Description of key information
Non flammable solid (EU Method A.10)
No flammability on contact with water (EU Method A.12)
No pyrophoricity (EU Method A.13)
Not self-heating (Melting point < 160 °C)
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
The test substance melted when approached by the ignition flame; no flame propagation was observed.
The substance does not emit flammable gases on contact with water.
The test item has no pyrophoric property in the sense of the test procedure.
The substance is completely molten at 160 °C and therefore does not need to be considered for classification as self-heating.
Justification for classification or non-classification
The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification:
The test substance melted when approached by the ignition flame; no flame propagation was observed (EU Method A.10).
The substance does not emit flammable gases on contact with water (EU Method A.12).
The test item has no pyrophoric property in the sense of the test procedure (EU Method A.13).
The substance has a melting point of 49.35 °C (-22.3 °C tehnical); the determination of self-heating behaviour is not relevant for substances that are completely molten at 160°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
