EC number: 232-504-3 | CAS number: 8060-28-4
Surface tension
Administrative data
- Endpoint:
- surface tension
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because water solubility is below 1 mg/L at 20°C
- Justification for type of information:
- A test was carried out in accordance to EU Regulation (EC) 440/2008, Annex Part A test A5 and OECD Test Guideline 115. The endpoint has been exempted under Column 2 of Annex VII (EC 440/2008) as the water solubiliy is <1 mg per litre.

Test material
- Reference substance name:
- Hop, Humulus lupulus, ext.
- EC Number:
- 232-504-3
- EC Name:
- Hop, Humulus lupulus, ext.
- Cas Number:
- 8060-28-4
- Molecular formula:
- No simple molecular formula for UVCB
- 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.
Constituent 1
- Specific details on test material used for the study:
- Hop extract batch number 160025. This is a liquid carbon dioxide extract of hops variety 'Cascade'.
Results and discussion
Any other information on results incl. tables
Two solutions were made up of the following dilutions: 10 mg per 10 ml and 1 mg per 1 litre. They were shaken and left for approximately 3 hours. After 30 minutes of sonication of the 1 mg per 1 litre solution the sample remained visible, therefore the sample's solubility is <1 mg per litre. This endpoint has been exempted under Column 2 of Annex VII (EC 440/2008) as the water solubility is <1 mg/L.
Applicant's summary and conclusion
- Conclusions:
- This endpoint has been exempted under Column 2 of Annex VII (EC 440/2008) as the water solubility is <1 mg/L.
