- Conclusions:
- In a GLP study conducted according to BS 4056, the auto-ignition temperature of EC# 457-320-2 was 298oC
- Executive summary:
In a GLP study conducted according to BS 4056, the auto-ignition temperature of EC# 457-320-2 was determined in an open Erlenmeyer flask in a refractory oven.
At temperatures between 200 and 296oC, no ignition was seen (the material giving off grey smoke only) after more than 300 seconds. At temperatures of 298 and 300oC the material burnt with a yellow flame after 66 and 68 seconds, respectively, and at 400oC after only 2 seconds. No ignition was obtained in the replicate samples heated to 296oC.
In conclusion, the auto-ignition temperature of EC# 457-320-2 test material was determined to be 298oC.

- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions

- Auto-ignition temperature:
- 360 °C
- Atm. press.:
- 1 029 mBar
- Auto-ignition temperature:
- 363 °C
- Atm. press.:
- 1 019 mBar
- Conclusions:
- The auto-ignition temperature of the test substance is 360°C at 1029 mbar.
- Executive summary:
The auto-ignition temperature is the lowest temperature at which the test substance will ignite when mixed with air under the conditions defined in the test method. The units are degrees Celsius.
A known volume of the test substance was injected into a heated open round-bottomed flask (500 m1) containing air. The contents of the flask were observed in a darkened room for ten minutes following injection of a sample or until ignition occurred. Due to the high viscosity of the test substance the material and syringe where kept at 100°C in order to reduce the viscosity and enable injections to be made. A temperature of 400°C was chosen as a starting point above the expected auto-ignition temperature. Test substance (100 ,.d) was injected into the flask, and observations made for auto-ignition up to a maximum time of 10 minutes. The test was repeated at this temperature using injection volumes of 150,200,250 and 50 ul to see if ignition would occur.
The auto-ignition temperature of the test substance is 360°C at 1029 mbar.

Given the chemical and structural similarities between EC: 457 -320 -2 and EC: 434 -650 -5, this study is considered suitable for read-across.

An auto-ignition temperature will be reported as the lower of the two obtained results for safety reasons.
Description of key information
In a GLP study conducted according to BS 4056, the auto-ignition temperature of EC# 457-320-2 was 298oC
A supporting GLP study on EC: 434-650-5 was also added to the dataset to support the chemical similarities between these substances. The auto-ignition temperature of EC:434 -650 -5 was concluded to be 360 degrees C.
Key value for chemical safety assessment
