Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Non explosive

Key value for chemical safety assessment

non explosive

Additional information

The substance starts to decompose from ca 296 °C with an exothermic energy lower than 500 J/g (i.e. 188 J/g).

Justification for classification or non-classification

According to the CLP Regulation (EC) No 1272/2008, 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 Direct Orange 118: the test item starts to decompose from 296 °C with an exothermic energy lower than 500 J/g (i.e. ca 188 J/g).

In conclusion, the substance can be considered non explosive, according to the CLP Regulation (EC) No 1272/2008.
