Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No study on explosive properties of Disperse Red 050 was available. Therefore, avaliable data on a similar substance, i.e. Disperse Orange 073 (EC 255 -037 -7, CAS 40690 -89-9) was used.
These substances share the same molecular structure and mainly differ for one alkyl chain on the tertiary amine, i.e. an ethyl chain in Disperse Red 050 and an ethylbenzoate in Disperse Orange 073. No effect on explosive properties is expected from such differences.
The study was conducted according to EU method A.14.
The method comprises three parts:
a) test of thermal sensitivity:
b) test of mechanical sensitivity with respect to shock;
c) test of mechanical sensitivity with respect to friction
The substance was found to be non-explosive.
Justification for classification or non-classification
According to the definition set out in the CLP Regulation (EC 1272/2008), an explosive substance or mixture is a solid or liquid substance or mixture of substances which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic substances are included even when they do not evolve gases.
Based on the available information, by following a read across approach, Disperse Red 050 was considered as non explosive.
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.
