Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 contact with the ignition source, the test substance melted. The melt could be ignited with the flame and burned. However, the test substance could not sustain a burning reaction. In conclusion, the test substance is not highly flammable according to the criteria as described in the EU method A. 10.
The chemical structure of the test substanc does not contain chemical groups, which may lead to the conclusion that the test substance is capable of developing a dangerous amount of (flammable) gas in contact with air, damp air or water. From the structural formula of the test substance it was concluded that the test substance is not pyrophoric. The test substance does not contain any chemical group that might lead to spontaneously ignition a short time after coming in contact with air at room temperature (circa 20°C).
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
The flammability of the test substance was determined according to EU method A.10. In contact with the ignition source, the test substance melted. The melt could be ignited with the flame and burned. However, the test substance could not sustain a burning reaction. In conclusion, the test substance is not highly flammable according to the criteria as described in the EU method A. 10. The flammability (contact with water) of the test substance was estimated according to EU method A.12. The chemical structure of the test substance does not contain chemical groups, which may lead to the conclusion that the test substance is capable of developing a dangerous amount of (flammable) gas in contact with air, damp air or water. The pyrophoric properties of the test substance were estimated according to EU method A.13. From the structural formula of Urea 6 it was concluded that the test substance is not pyrophoric. The test substance does not contain any chemical group that might lead to spontaneously ignition a short time after coming in contact with air at room temperature (circa 20°C).
Justification for classification or non-classification
Based on the flammability experiment, the structure of the molecule and experience in handling and use, the test substance was not classified and labelled as flammable, flammable in contact with water and pyrophoric according to Directive 67/548/EEC (DSD) and Regulation 1272/2008/EEC (CLP).
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.
