Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to the Endpoint Specific Guidance R.7a, the primary value used to assess the ease of ignition for liquids and low melting point solids is the flash point. As 2,6-xylenol is a low melting point solid (melting point 46 °C), the flash point data is considered to be more appropriate than the flammability test for solid substances. It is therefore considered to be justified to omit the flammability test required under point 7.10 of Annex VII.
In accordance with point 1 of Annex XI, it is considered justified to omit the testing for pyrophoric properties and testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not possess pyrophoric properties or emit flammable gases in contact with water.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
Supporting information is also included. Two sources of data are provided; these are experimental values reported in formats which have been peer reviewed. Both were awarded a reliability score of 2 in accordance with the criteria for assessing data quality as set forth by Klimisch et al. (1997).
The first experimental value reported was obtained from the Physical and Thermodynamic Properties of Pure Chemicals - Data Compilation and Hazardous Chemicals Data Book. The gas upper and lower explosion limits were reported as 1.4 and 6.4 %, respectively. The upper limit was predicted by the method of Shebeko.
The second value was reported in Japan’s National Institute of Technology and Evaluation database and the Merck Chemical Data Base. 2,6-Xylenol was determined to be flammable at ≥ 1.4 vol %.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the substance does not require classification with respect to flammability.
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.
