- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)

- Specific details on test material used for the study:
- Source: ExxonMobil Research and Engineering (Paulsborro, NJ)
Lot: 17-064163-4
- Expiration date of the lot/batch: 20 March 2019
-Purity test date: 25 September 2017
Appearance: Light grey powder
Storage conditions:Room temperature, keep container tightly closed - Key result
- Relative self-ignition temperature:
- 270 °C
- Conclusions:
- In the investigation of self-ignition in the Grewer-oven for the pure test item and for the test item in mixture with Kieselguhr a self-ignition could be oberserved at a temperature of 270 °C.
- Executive summary:
In the investigation of self-ignition in the Grewer-oven for the pure test item and for the test item in mixture with Kieselguhr a self-ignition could be observed at a temperature of 270 °C. Therefore Lithium Salicylate is not classified as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation or according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.11.
Reference
In the investigation of self-ignition in the Grewer-oven an endothermic process was observed for the pure test item and the test item in mixture with Kieselguhr in the temperature range of 230 to 270 °C. For the pure test item an exothermic process was detected starting at a temperature of approx. 270 °C that led to a maximum temperature of approx. 530 °C (corresponding oven temperature 305 °C). After the measurement a black residue remained in the wire basket.
For the test item in mixture with Kieselguhr an exothermic process was detected starting at a temperature of approx. 270 °C that led to a maximum temperature of approx. 470 °C (corresponding oven temperature 290 °C).
Description of key information
In the investigation of self-ignition in the Grewer-oven for the pure test item and for the test item in mixture with Kieselguhr a self-ignition could be observed at a temperature of 270 °C. Therefore Lithium Salicylate is not classified as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation or according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.11.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 270 °C
Additional information
Since the study was GLP compliant and followed the aforementioned guidelines, the study was given a reliability rating of 1 (reliable without restrictions).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
