Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with section 2 of REACH Annex XI, a study is technically not feasible as the substance is a liquid. The flammability of a liquid is described by the flash point.
The test item contains none of the functional groups quoted in UN-Manual Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria (fifth revised edition, appendix 6, article 5.3) which may react with water to emit flammable gases. Therefore, it can be concluded by expert judgement that ‘Dibenzylether' does not emit flammable gases in contact with water. Testing according to UN Procedure N.5 is not necessary.
In accordance with section 1 of REACH Annex XI, a study does not need to be conducted as it is scientifically unjustified. Based on experience during handling and use, no pyrophoric properties were observed and the structure does not give a reference to pyrophoric properties."

Additional information
Justification for classification or non-classification
Dibenzyl ether is not yet classified in the Annex I of Directive 67/548/EEC. According to the information summarized in this below, no classification on flammability is needed:
- As liquid, no flash point up to 249 °C;
- As liquid, boiling point is higher than 300 °C;
- No pyrophoric property, based on experience from production and handling;
- It does not ignite spontaneously with water and does not liberate flammable gases in hazardous amounts in contact with water.
Based on the data summarized above, dibenzyl ether is also not flammable according to GHS (Regulation EC 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.
