The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
