Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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.

Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Up to 2008
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP status not known, guideline not known, information from a published handbook, acceptable with restrictions.
- Principles of method if other than guideline:
- The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.
- GLP compliance:
- not specified
- Type of method:
- other: No data reported.
- Key result
- Flash point:
- -22 °C
- Atm. press.:
- 101.3 kPa
- Remarks on result:
- other: Standard pressure assumed.
- Conclusions:
- The flash point of Normal-Hexane is -22°C.
- Executive summary:
The flash point of Normal-Hexane has been taken from the CRC Handbook (Lide 2008). No information on the primary source of this data or the methods used is available. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.
Reference
Description of key information
The flash point is < -20°C for n-hexane
Key value for chemical safety assessment
Additional information
The flash point is < -20°C for n-hexane according to methodology DIN 51755. This range has been agreed by the consortium to represent the substance.
