Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- September 06, 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- not specified
- Type of method:
- plate method
- Remarks:
- DIN EN 14370 (replaced DIN 53914), estimation by ACD Percepta software
- Key result
- Surface tension:
- 28.9 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: 28.9 ± 0.14
- Conclusions:
- Under the study conditions, the surface tension of the test substance is determined to be 28.9 ± 0.14 mN/m at 20 °C.
- Executive summary:
A study was conducted to determine the surface tension of the test substance using plate method according to OECD Guideline 115. The test substance was diluted to a content of 1 g/L (repeated determination), and clarified via pressure filtration with PORAFIL 0.2 μm. The resulting solutions are visual clear, but they are colloidal solutions (tested using a laser). Solutions were measured twice by KRÜSS K 100 MK2 with detection speed of 6 mm/min and detection sensitivity: 0.01 g. Immersion depth was of 2 mm. Double distilled water and 1 -octanol have been measured as calibration and control sample. Under the study conditions, the surface tension of the test substance is determined to be 28.9 ± 0.14 mN/m at 20 °C (Mund, 2017).
