Version / remarks:
2002. Remark: ASTM-D93
GLP compliance:
Type of method:
non-equilibrium method open cup
Flash point apparatus:
Pensky-Martens apparatus
Key result
Flash point:
176 °C
Atm. press.:
102.3 kPa
Key result
Flash point:
179 °C
Atm. press.:
ca. 102.8 kPa

Measurement parameters

Rotation Speed of the Sample Stirrer: 100 rpm

Expected Flash Point of Sample: 195.0°C


(repeat determination)

Temperature of Initial Ignition Source Application: 170.0°C / 170.0°C

Atmospheric Pressure: 102.8 kPa / 102.3 kPa

Flash Point (Uncorrected): 179.4°C / 176.7°C

Flash Point (Corrected): 179.0°C / 176.5°C

Interpretation of results:
GHS criteria not met
A flash point value of 176°C at atmospheric pressure was determined for the substance using a relevant test method. The result is considered to be reliable.
Executive summary:

Icosan-1-ol was determined according ASTM D 93. The Flash point was determined to be 176°C at atmospheric pressure.

Description of key information

The flash point of a commercial sample of icosan-1-ol is 176°C at 1013 hPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
176 °C

Additional information

A flash point value of 176°C at 1013 hPa was determined for icosan-1-ol with use of non-equilibrium closed-cup method in accordance with ASTM-D93. The result is considered to be reliable and is selected as key study.

It is supported by an open cup flash point value of 194°C at 1013 hPa measured in a separate test.

A flash point value of 176°C indicates that icosan-1-ol should not be classified for flammability in accordance with Regulation (EC) No. 1272/2008.

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:

The flash point of Category substances follow a predictable trend of increasing flash point temperature with increasing chain length together with increasing boiling point and decreasing vapour pressure.
