Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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.
GLP compliance:
not specified
Type of method:

Conclusions:
The flash point of ethylbenzene is 18˚C.
Executive summary:

No information on 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 for this endpoint.

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.
