Test material

Constituent 1
Reference substance name:
Hop, Humulus lupulus, ext.
EC Number:
232-504-3
EC Name:
Hop, Humulus lupulus, ext.
Cas Number:
8060-28-4
IUPAC Name:
Hop, Humulus lupulus, ext.
Test material form:
liquid: viscous
Remarks:
Depending on the extraction conditions and on the hop variety, the colour of the extract can vary from yellow to dark green. It is a semi-fluid paste at room temperature. The product becomes more fluid when heated.
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.
