* = Due to the sample boiling higher test temperatures could not be attained and therefore testing was terminated

Comment: No flash observed the sample started boiling at approximately 210 °C, producing grey vapours which extinguished the test flame. Testing was terminated at 228 °C.

Interpretation of results:
GHS criteria not met

Description of key information

>228 °C at 1011-1018 hPa (EU A.9, closed cup)

Key value for chemical safety assessment

Additional information

The flash point of the substance Propyleneglycol dioleate (CAS 105 -62 -4) was determined in a Pensky-Martens closed cup apparatus. No flash point could be determined due to sample boiling / decomposition at 228 °C under test conditions.

Supporting information measured with an open cup method (205 °C) confirmed a flash point >200 °C.
