Auto flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Thermal stability of the oil samples was analysed using the Thermogravimetric Analyzer (Model Q50, TA Instruments, New Castle, DE). Approximately 1-1.2 mg of the oil sample was added to an aluminium pan, the pan was placed in the furnace, and the exact sample weight was determined. The sample was heated to 700 °C under air atmosphere at an increasing rate of 5 °C/min. Sample weight differences were automatically recorded every 0.5 sec. Collected data were analysed and plotted using the TA Universal Analyzer Software. The graph was normalized based on the sample weight basis.
- GLP compliance:
- not specified
- Specific details on test material used for the study:
- Menhaden fish oil extracted using a rendering process was obtained from a commercial source (Omega Protein Inc., Houston.TX). Measurements were conducted using the crude oil and several differently refined oils.
- Auto-ignition temperature:
- > 550 °C
- Remarks on result:
- other: Pressure not specified.
- Conclusions:
- All samples were thermally decomposed between 200 °C and 500 °C. In no case auto-ignition was reported (up to 550 °C).
- Executive summary:
In this publication by Yin 2011 measurements regarding the thermal stability of unrefined and refined menhaden oil are described. The thermal decomposition of oil samples under ambient conditions was investigated by thermal gravimetric analysis (TGA). All samples were found to decompose at elevated temperatures above 200 °C. Auto-ignition was not reported.
Reference
Thermal degradation of all oils was observed between 200 °C and 500 °C. The sample weight was decreased below 2% of the initial value in all cases. No auto-ignition was reported (up to 550 °C).
Description of key information
In a study regarding the thermal stability of menhaden oil no auto-ignition was reported. The thermal decomposition of oil samples under ambient conditions was investigated by thermal gravimetric analysis (TGA). All samples were found to decompose at elevated temperatures above 200 °C.
Key value for chemical safety assessment
