Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Not combustible, train of powder, Bailey 2013
Not flammable in contact with water (based on chemical structure).
Not pyrophoric (based on chemical structure).
Not self-reactive (see Section 4.23)
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
A single study for combustible solids (Bailey 2013) was available. The train of powder method was used and only a localised ignition accompanied with rapid extinction without propagation was observed.
Comparison of the chemical structure with the functional groups listed in Recommendations on the Transport of Dangerous Goods, Manual of tests and criteria, Appendix 6, 5.3 (p. 442), indicates the substance is unlikely to be flammable on contact with water. In addition, experience in the handling and use of the substance has indicated no properties associated with flammability on contact with water. As a result, and according to Annex XI, section 1.2, based on the weight-of-evidence, testing for this endpoint is considered to be unnecessary.
Comparison of the chemical structure with the functional groups listed in Bretherick’s Handbook of Reactive Chemical Hazards, 6th Ed., Vol. 2, Pyrophoric materials (p. 343), indicates the substance is unlikely to have pyrophoric properties. In addition, experience in the handling and use of this substance has given no indication that it has pyrophoric properties. As a result, and according to Annex XI, section 1.2, based on the weight-of-evidence, testing for this endpoint is considered to be unnecessary.
See Section 4.23 Additional physico-chemical information, for a discussion of self-reative substance properties.
Justification for classification or non-classification
According to the criteria as described by Directive 67/548/EEC, and as amended by Directive 2001/59/EEC, Annex VI, 2.2.4., the substance may be considered not-flammable based on the observation that after removal of the source of ignition the substance doesn't continue to burn or to be consumed.
The substance is not considered to be classified for flammability according to the criteria as described by Regulation (EC) 1272/2008, Annex I, Part 2, 2.7., because the substance is not readily combustible. The available data are considered reliable and suitable for classification. As a result, this substance does not meet the criteria for classification under Regulation (EC) No. 1272/2008.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
