Description of key information

The flash point of Alcohols, C9-11-linear and branched is expected to be =98°C on the basis of read across, expert judgement and weight of evidence. A value of 108°C is reported in reliable secondary literature.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
98 °C

Additional information

There is no reliable measured flash point available for the submission substance. However, flash point has been assessed based on available data for commercial samples of analogous mono-constituent substances (nonan-1-ol, decan-1-ol and undecan-1-ol). Nonan-1-ol, decan-1 -ol and undecan-1-ol have measured flash point values of 98.75°C at 1013 hPa, 107°C at 1013 hPa and 108°C at 1013 hPa respectively with the use of a closed-cup method in accordance with ASTM D-93 test method. The results are considered to be reliable and are used as weight of evidence that the flash point of the submission substance is expected to be =98°C at 1013 hPa.

These conclusions are supported by a closed cup flash point of 108°C reported in company product literature for this UVCB. In view of the low level of detail about the method used, the result cannot be confirmed to be reliable.

A flash point of =98°C and boiling point of 213 -245°C indicate that Alcohols, C9-11-branched and linear should not be classified as a flammable liquid 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.
