Executive summary:

The ignition temperature of choline chloride (Additives: colloidal silica 35 %, water 15 %) was investigated according to the German national guideline VDI 2263, Blatt 1, Kap. 2.6 ("BAM-Ofen") (BASF AG, 1988). As result, a value of 330 °C is reported.

Description of key information

VDI 2263_BAM Ofen_Ignition temperature: 330 °C

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
330 °C

Additional information

The key value was determined according to the German guideline VDI 2263 (BASF AG, 1988). The study was considered to be well-performed and consequently the results are reliable and sufficient to cover this endpoint, no datagaps were identified.


The value can be seen as a worst-case value because the sample was applied to the test as a dust. Due to the high surface of dusty solids the ignition is more possible or lower than for more coarse solids. This is supported by handbook/collection of data (Gestis, 2022) were a higher self-ignition temperature is reported (430 °C) for the substance.
