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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP status 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 Merck Index states that physical data are cited as found in the literature. When several alternate data values appear in the literature, the data is evaluated and representative selections are made; values are then reported with the corresponding source. 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.

Description of key information
The flash point of the xylene isomers and ethylbenzene ranges from 18-32˚C. The flash point of m-xylene is 27˚C, o-xylene has a flash point of 32˚C, for p-xylene it is 27˚C and for ethylbenzene it is 18°C. The lowest value of 18˚C will be used for the risk assessment.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 18 °C
Additional information
The Merck Index (O'Neil, 2006) is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. The data are supported by results from the CRC Handbook (Lide 2008), which gives flash points for m-xylene, o-xylene, p-xylene and ethylbenzene of 27, 32, 27 and 21°C respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
