Description of key information
The flash point of hexan-1-ol is 60°C.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 60 °C
Additional information
The flash point of 60°C at 1013 hPa was determined for hexan-1-ol with use of non-equilibrium closed-cup method in accordance with ASTM-D93. The result is considered to be reliable.
The key study is supported flash point values of 62°C and 63°C available in other sources.
A flash point value of 60°C and boiling point of 155°C indicate that hexan-1-ol should be classified as a flammable liquid category 3 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.
