α-Bitter acids, hop, hydrogenated, isomerized

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.

Results and discussion

Any other information on results incl. tables

1g/L solution was made up and sonicated for approximately 1.75 hours, the solution became cloudy. Another solution of 1mg/L was made up and sonicated; the sample did not dissolve into the solution, hence the estimated water solubility is < 1mg/L therefore testing does not need to be conducted.

Result : Exempted

Comments

This endpoint has been exempted under Column 2 of Annex VII (EC 440/2008) as the water solubility is < 1mg/L.
