Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Drop volume tensiometers serve to measure the surface and interfacial tension of liquids. The method is especially suited to determining dynamic interfacial tensions. Here, the volume of a drop detaching from the needle is measured very precisely. The surface/interfacial tension is derived from this depending on whether the drop forms in air or in a second non-miscible phase (oil).
- GLP compliance:
- no
- Type of method:
- other: Drop volume tensiometers
- Key result
- Surface tension:
- 25.82 mN/m
- Temp.:
- 20 °C
- Remarks on result:
- other: The test was performed with the pure substance. Therefore, concentration ist not applicable.
- Conclusions:
- The surface tension of the test item was determined to be 25.82 mN/m at 20 °C.
- Executive summary:
The determination of the surface tension of the test item was performed using a drop volume tensiometer. The surface tension of the test item was determined in a temperature range between 20 to 80 °C. The surface tension was determined to be 25.82 mN/m at 20 °C. Due to the fact that the surface tension is lower than 60 mN/m, the test item has surface-active properties.
