Description of key information
Pure EPTAC is a highly flammable solid (but not placed on the market as such).
Aqueous solutions up to 75% are not flammable.
Key value for chemical safety assessment
- Flammability:
- highly flammable
Additional information
Testing according to EC A10 method, similar to UN N1 (without wetted zone), under GLP.
Method not specified for flash point measurement.
Justification for classification or non-classification
Based on the burning rate of <45 sec., the substance as a solid fulfills criteria for classification as highly flammable (R11) according to Directive 67/458/EEC (DSD), and as flammable solid according to Regulation (EC) No.1272/2008 (CLP) criteria, but hazard category could not be assigned.
Based on the flash point >60°C, aqueous solutions up to 75% do not fulfill criteria for classification as flammable liquid according to Directive 67/458/EEC (DSD) and Regulation (EC) No.1272/2008 (CLP) criteria.
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.
