Description of key information
Relative self-ignition temperature of surrogate substance (Quaternary ammonium compounds, C20-22-alkyltrimethyl, chlorides): >400 °C.
Key value for chemical safety assessment
Additional information
The relative self-ignition temperature of the surrogate substance (Quaternary ammonium compounds, C20-22-alkyltrimethyl, chlorides) was determined according to EEC guideline 92/69/EWG A.16. The temperature/time-curves of the test item and oven were recorded simultaneously. The oven temperature was increased beginning at room temperature up to 400 °C at a rate of 0.5 °C/min. No self-ignition was observed up to the stop-temperature of 400 °C.
The surrogate substance differs from the submission substance primarily in the anion (surrogate substance: chloride). The carbon chain lenght distribution, which is considered as decisive for the auto-flammability, is about the same.
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.
