Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Non explosive
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
A screening evaluation for the explosive properties of the test substance was carried out according to internationally accepted guidelines. Analysis of the chemical structure reveals that no alert structures for explosive properties are present in the molecule. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g.
Justification for classification or non-classification
According to the CLP Regulation (EC) No 1272/2008, 2.1.4.2. Screening procedure section, the screening procedure is aimed at identifying the presence of such reactive groups and the potential for rapid energy release. If the screening procedure identifies the substance or mixture to be a potential explosive, the acceptance procedure (section 10.3 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria) has to be performed.
Screening procedure failed to evidence any reason for concern, on the basis that the enthalpy of decomposition of Fluorescent Brightener 363 was below 500 J/g.
In conclusion, the substance can be considered non explosive, according to the CLP Regulation (EC) No 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).
