Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
1 (reliable without restriction)
according to guideline
EU Method A.9 (Flash-Point)
GLP compliance:
Type of method:
closed cup
Specific details on test material used for the study:
An oil-rich hop extract, from hop variety 'Target' batch number BI/YYF/1701 was used. The essential oil content was 30.6% v/w. A high-oil extract was deliberately chosen since hop extract is a UVCB and it is the essential oils that are the only potentially flammable component. Therefore the flash point of a high-oil extract will provide a suitable flammability classification for all hop extracts.
Key result
Flash point:
ca. 81 °C
Atm. press.:
ca. 101.1 kPa
Interpretation of results:
GHS criteria not met
Hop extract is not classified as a flammable liquid.
