Specific details on test material used for the study:
- Batch: D05/38
- Expiration date: 30 August 2021
- Purity: 97.36%
- Storage condition of test material: Room temperature in the dark
Key result
Relative self-ignition temperature:
>= 400 °C
Remarks on result:
no self ignition observed under the test conditions

- Results: The sample did not reach 400°C by self-heating. On completion of testing, a white and grey residue remained.

Conclusions:
Under the conditions of the test, potassium 12-hydroxystearate did not ignite by self-heating below a temperature of 400°C.
Executive summary:

The relative self-ignition temperature of potassium 12 -hydroxystearate was investigated in a GLP-compliant study following EC method A.16. Under the conditions of the test, potassium 12-hydroxystearate did not ignite by self-heating below a temperature of 400°C.
