Reference
Endpoint:
auto-flammability
Type of information:
experimental study
Adequacy of study:
key study
Study period:
6 September 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
according to
Guideline:
other: Not stated
Principles of method if other than guideline:
A condenser was used to collect any distillate from the substance, with a thermometer measuring the temperature of the test substance, and a second thermometer to monitor the condensate temperature. The sample was heated in air through a range of 150 ºC to 270 ºC.
GLP compliance:
no
Key result
Auto-ignition temperature:
> 270 °C
Atm. press.:
ca. 101 325 Pa
Remarks on result:
other: The sample was not observed to ignite during the test

At approximately 160 ºC, the sample was seen to ‘smoke’, with no evidence of distillation or ignition, and no temperature rise at the condenser. The sample was noted to be darker in colour. Heat was continually applied until the sample reached 270 ºC. The sample was not observed to ignite.

Conclusions:
The auto-ignition temperature of Fatty acids, C12-20 and C12-20-unsatd., 2-ethylhexyl esters cannot be determined as the substance begins to degrade before the autoignition point is reached.
Executive summary:

A condenser was used to collect any distillate from the substance, with a thermometer measuring the temperature of the test substance, and a second thermometer to monitor the condensate temperature. The sample was heated in air through a range of 150 ºC to 270 ºC.

The sample was not observed to ignite during the test. At approximately 160ºC, the sample was seen to ‘smoke’, with no evidence of distillation or ignition, and no temperature rise at the condenser. The sample was noted to be darker in colour.

Heat was continually applied until the sample reached 270ºC. The sample was not observed to ignite.

Description of key information

During the study to determine the boiling point of the sample, heat was continually applied until the sample reached 270 oC. Not ignition was observed. 

Key value for chemical safety assessment
