Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: ISO 9101
- Deviations:
- no
- Principles of method if other than guideline:
- Drop volume method: measurement of the volume of an aqueous phase formed at the end of a vertical capillary tube
when it detaches from the tube in contact with the organic phase.
The interfacial tension is obtained between two liquid phases by balancing the weight of the drop with the interfacial
tension force supporting it and applying a correction factor. The interfacial tension is then calculated from
the volume of the falling drop, the outer capillary radius, the density difference between the two liquid phases
and the acceleration due to the gravity. - GLP compliance:
- no
- Type of method:
- other: ISO 9101

Any other information on results incl. tables
The actual concentration of Dihydrolinalool in the aqueous phase was not determined. The aqueous phase was saturated with Dihydrolinalool prior to determination of surface tension. The actual water solubility was anticipated.
