Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Endpoint:
- flash point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2002
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The result was obtained from a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable.
Data source
Reference
- Reference Type:
- review article or handbook
- Title:
- Unnamed
- Year:
- 2 002
Materials and methods
- Principles of method if other than guideline:
- Pensky Martens apparatus according to 67/548 Annex V.
- GLP compliance:
- no
- Type of method:
- closed cup
Test material
- Reference substance name:
- propylene oxide
- IUPAC Name:
- propylene oxide
- Reference substance name:
- Methyloxirane
- EC Number:
- 200-879-2
- EC Name:
- Methyloxirane
- Cas Number:
- 75-56-9
- IUPAC Name:
- 2-methyloxirane
- Details on test material:
- Test material was racemate from both R(+) and S(-) propylene oxide. This endpoint is not measured / determined with enantio-selective sensors.
Therefore the R(+) value is identical to the racemate endpoint.

Results and discussion
Flash point
- Flash point:
- -40 °C
- Remarks on result:
- other: Average taken from studies which used an approved testing method.
Any other information on results incl. tables
The flash point (closed cup) has been reported as -44°C (BASF AG Material Safety Data Sheet, 1995) and -37°C (Elm, R, cited in Ullmans Encyklopädie der technischen Chemie, 1980). Both tests were reportedly conducted using an accepted Annex V test method (Penskey-Martens apparatus) and although actual data were not provided, these values are supported by estimates based on vapour pressure and lower explosive limit data which gave values of between -43.4°C and -38.4°C. Values of -35°C and -37°C are widely quoted in secondary sources.
Applicant's summary and conclusion
- Conclusions:
- A flash point of the substance of -40°C was selected from the available literature data. Together with a boiling point below 35°C the substance must therefore be classified as “Extremely Flammable R12 / H224".
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
