Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 classified as flammable
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
In order to evaluate the flammability of the test substance, a study was conducted according to the method A.10 of EEC-Directive 92/69 EEC.
The substance could not be ignited with a flame during the preliminary test (contact time of about 2 minutes). In contact with the ignition source, the substance melted. The flame of the gas burner changed its colour to orange. A violet melt remained with a crusty surface.
Justification for classification or non-classification
According to the CLP Regulation (EC 1272/2008) powdered, granular or pasty substances or mixtures (except powders of metals or metal alloys — see 2.7.2.2) shall be classified as readily combustible solids when the time of burning of one or more of the test runs, performed in accordance with the test method described in Part III, sub-section 33.2.1, of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, is less than 45 seconds or the rate of burning is more than 2,2 mm/s.
No ignition was observed throughout the course of the test. The substance is not classified as flammable.
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.
