Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance does not have to be considered as flammable solid, gas or liquid, flammable in contact with water, flammable aerosol, pyrophoric solid, pyrophoric liquid or self-heating substance.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Flammable gases
The test item is a solid at ambient conditions. This hazard class is only applicable for gases. Thus, the substance was not considered for classification as flammable gas.
Flammable liquid
The test item is a solid at ambient conditions. This hazard class is only applicable for liquids. Thus, the substance was not considered for classification as flammable liquid.
Flammable aerosol
The test item is a solid at ambient conditions. This hazard class is only applicable for liquids. Thus, the substance was not considered for classification as flammable aerosol.
Flammable solids
The substance does not contain groups that may react with oxygen, thus it is not expected to propagate combustion along a test substance pile, and is therefore considered not flammable. In accordance with REACH Annex XI, testing may be omitted if testing does not appear scientifically necessary.
Pyrophoric liquids
The test item is a solid at ambient conditions. This hazard class is only applicable for liquids. Thus, the substance was not considered for classification as pyrophoric liquid.
Pyrophoric solids
In accordance with section 2.10.4 Annex I of Regulation (EC) No 1272/2008 and ECHA guidance on the application of CLP Criteria section 2.10.4.2 the classification procedure for pyrophoric solids need not to be applied when experience in manufacture or handling shows that the solid does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the solid is known to be stable at room temperature for prolonged periods of time (days)). Based on the experience in handling and use the substance is not known to ignite spontaneously when coming into contact with air at normal temperatures. Thus, no study was conducted and the substance was not considered for classification as pyrophoric solid.
Self-heating substances and mixtures
In accordance with ECHA guidance on the Application of the CLP Criteria section 2.11.4.2 and ECHA guidance on IR/CSA chapter R.7a section R7.1.10.7,substances with a low melting point (< 160 °C) should not be considered for classification in this class since the melting process is endothermic and the substance-air surface is drastically reduced. The study on self-heating properties has not to be conducted as the melting point of the test substance is far below 160 °C (starting at about 23 °C and ranging up to 93 °C) and the substance iscompletely moltenup to this temperature.
Substances which, in contact with water, emit flammable gases
In accordance with column 2 of REACH Annex VII and with Regulation (EC) No 1272/2008 Annex I section 2.12.4 and ECHA guidance on the application of CLP Criteria section 2.12.4.2 the classification procedure for this hazard class need not to be applied. Based on the experience in handling and use the substance does not react with water. Thus, no study was conducted and the substance was not considered for classification.
Flammable Aerosols
Section 2.4.2 of Guidance on the application on the CLP Criteria state as follows: “Aerosols, this means aerosol dispensers, are any non-refillable receptacles made of metal, glass or plastics and containing a gas compressed, liquefied or dissolved under pressure, with or without a liquid, paste or powder, and fitted with a release device allowing the contents to be ejected as solid or liquid particles in suspension in a gas, as a foam, paste or powder or in a liquid state or in a gaseous state." Thus, as the substance does not meet the definition for aerosol, the test for aerosols was waived. Consequently the substance has not to be considered for classification for this hazard class.
In conclusion, the substance does not have to be considered as flammable solid, gas or liquid, flammable in contact with water, flammable aerosol, pyrophoric solid, pyrophoric liquid or self-heating substance.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
In accordance with Annex I Section 2.2, Section 2.3, Section 2.6, Section 2.9, Section 2.10 Section, 2.11 and Section 2.12 of Regulation (EC) No 1272/2008, as amended for tenth time in Regulation (EC) No 2017/776, and UN GHS Rev 6 (2015) the test item has not to be classified as flammable solid, self-heating substance in Class 4 Division 4.2, substances which in contact with water emit flammable gases in Class 4 Division 4.3, pyrophoric liquid, pyrophoric solid in class 4 Division 4.2, flammable gases in class 2 or as aerosol in class 2.
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.
