Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Study period:
- 2010-10-26
- Reliability:
- 1 (reliable without restriction)
- Justification for type of information:
- Auto-flammability for cesium acetate has been extrapolated from read-across with others cesium salts (cesium nitrate, cesium chloride, cesium sulfate and cesium iodide) and cesium hydroxide. All cesium salts and cesium hydroxide used for the read-across have similar physchem data. In addition, for these cesium components, the auto-flammability has been determined experimentally. None of them was classified as auto-flammable. Therefore, it has been concluded that cesium acetate should not be auto-flammable. Further details on read-across strategy are available in section 13 of this dossier.

- Executive summary:
Cesium chloride was tested for self-ignition in a study according to EU Method A.16. The ambient temperature showed nearly a straight line. Up to about 400 °C no exothermic reaction of the sample was observed. Consequently, the self-ignition temperature for the test item must be > 400 °C, if any at all.

Description of key information
Auto-flammability for cesium acetate has been extrapolated from read-across with others cesium salts (cesium nitrate, cesium chloride, cesium sulfate and cesium iodide) and cesium hydroxide. All cesium salts and cesium hydroxide used for the read-across have similar physchem data. In addition, for these cesium components, the auto-flammability has been determined experimentally. None of them was classified as auto-flammable. Therefore, it has been concluded that cesium acetate should not be auto-flammable.
