Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- 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
- 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
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACh Annex XI, study for pyrophoric properties is deemed unnecessary based on the experience in handling, testing and use of the substance and based on the chemical structure of the known constituents of the substance that do not fall into critical categories described in ECHA guidance.
The tests performed on the substance and reported in this dossier showed that the substance clearly does not react with air. Moreover, a review of the chemical structure of the known constituents suggests that there are no chemical groups present in these constituents that would imply pyrophoric properties. Therefore, the study was considered as unnecessary. - Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 26 March 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is considered to be adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- Version / remarks:
- 2019
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspected on 15-16/11/2017, Signed on 15/05/2018
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- No ignition was observed throughout the course of the test.
- Executive summary:
The study was conducted according the procedure Test N.1 of the United Nations Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria (GLP).
In the preliminary screening test following the UN method, the test item was heated with the flame of a teclu burner. The test item melted to a brown liquid and the flame became orange. No ignition occurred within two minutes.
No ignition was observed throughout the course of the main test.
The test item should be considered as non-flammable solid (for UN regulations).
No observations were made which might cause doubts concerning the validity of the study outcome.

Findings
Safety Pre-Test
The test item melted and burned with an orange, sooting flame.
Preliminary Screening Test
In the preliminary screening test following the UN method, the test item was heated with the flame of a teclu burner. The test item melted to a brown liquid and the flame became orange. No ignition occurred within two minutes.
Results and Discussion
No ignition was observed throughout the course of the test.
The test item should be considered as non-flammable solid (for UN regulations).
No observations were made which might cause doubts concerning the validity of the study outcome.
Description of key information
Flammability: No ignition was observed throughout the course of the test.
NOT flammable if contact with air or water (waived).
NO self-heating properties anticipated (waived).
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
The evaluation of the Flammability of the substance according to UN Test N.1 (no flammable).
Based on the chemical structure and experience, no flammable properties are anticipated if contact with air or water, or no self-heating for solids with MP below 160°C, therefore studies were deemed unnecessary.
