Description of key information
Auto-ignition temperature: > 450 °C at 101 kPa (75 % aqueous solution of Choline bicarbonate, ASTM E 659-78 –Standard Test Methods for Autoignition Temperature of Liquid Chemicals
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 450 °C
Additional information
The study was performed in a well-documented study according the relevant standard method ASTM E 659-78 – Standard Test Methods for Autoignition Temperature of Liquid Chemicals.
The auto-ignition temperature of a 75 % aqueous solution of Choline bicarbonate was determined to be > 450 °C. The determination of the auto-ignition temperature of a 75 % solution is reasonable because this is the marketed form, the substance is not isolated and is additionally hygroscopic. Since the auto-ignition temperature of the test item was > 450 °C, determined in two trials revealing consistent results, and is hence in the expected range, this value is considered as reliable and can be used for further risk assessment.
The outcome of the study is reliable without restrictions, consistent within the expected range and determined by a suitable method. Hence, no datagaps were identified, the study meets fully the tonnage-driven data requirements under REACH and not further testing needs to be performed.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.
