Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From September 18, 2017 to September 28, 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Version / remarks:
EU Regulation (EC) 440/2008, Annex Part A
Deviations:
no
GLP compliance:
yes
Type of method:
closed cup
Flash point apparatus:
Pensky-Martens apparatus
Key result
Flash point:
172 °C
Atm. press.:
101.3 kPa
Remarks on result:
other: Temperature correction applied due to non-standard barometric pressure (100.9 - 101.0 kPa)

The test standard used states that temperature corrections need to be made to the result if the ambient barometric pressure differs from a standardised (sea level) reading of 101.3 kPa. As barometric pressure has an effect on a liquid’s vapour pressure this means more or less volatiles could be present at the same test temperature under examination (depending on the local barometric pressure of any given test laboratory) and to remove this variable all results are harmonised to the same barometric pressure.

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of PPG-2 myristyl ether propionate was determined to be 172.0 °C (corrected) at 101.3 kPa. The substance does not meet the criteria for a flammable liquid according to CLP Regulation (EC) No. 1272/2008.
Executive summary:

An GLP-compliant experiment was performed to determine the flash point of PPG-2 myristyl ether propionate in line with EU Method A.9 (Flash-Point) of EU Regulation (EC) 440/2008, Annex Part A. A closed cup technique with Pensky-Martens apparatus was utilised. No deviation from protocol was reported. The flash point is deemed to be the lowest temperature at which the presence of a flame results in an ignition of the vapour. The experiment was undertaken in triplicate and as the ambient barometric pressure readings (100.9 - 101.0 kPa) were noted to be different to the standardised sea level reading of 101.3 kPa, a temperature correction was applied to the result. The flash point for PPG-2 myristyl ether was determined to be 172.0 °C (corrected) at 101.3 kPa. This value does not fit the CLP Regulation (EC) No. 1272/2008 criteria for flammable liquids.

Description of key information

PPG-2 myristyl ether propionate was found to have a flash point of 172.0 °C (corrected) at 101.3 kPa. In accordance with CLP Regulation (EC) No. 1272/2008, the substance does not fulfil the criteria of a flammable liquid.

 

Key value for chemical safety assessment

Flash point at 101 325 Pa:
172 °C

Additional information

This result is concluded to be a valid endpoint value given that it was obtained from a key study performed in line with Good Laboratory Practise (GLP) and EU Method A.9 (Flash-Point) of EU Regulation (EC) 440/2008, Annex Part A, without deviation. A Klimisch score of 1 (reliable without restriction) is proposed.
