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:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 67.41 mN/m
- Temp.:
- 19.6 °C
- Conc.:
- 0.1 vol%
- Remarks on result:
- other: Mean value from 2 samples with 5 measurements each
- Conclusions:
- According to the criteria mentioned in OECD Guideline 115, substances showing a surface tension lower than 60 mN/m under the conditions of this method should be considered surface active.
Test item surface tension in water was determined to be 67.4 mN/m at 19.6 ± 0,1 °C, therefore the substance is not surface active. - Executive summary:
The determination of the surface tension of an aqueous solution of the substance was based on the OECD Guideline 115, using the ring method. The calibration factor of the tensiometer used was determined to be 1.0304.
Two different experiments were performed using two different samples. Surface tension was measured 5 times for each sample. The surface tension of test item, calculated as the mean value of all measurements and corrected for calibration and correction factors, was found to be 67.4 mN/m at 19.6 ± 0.1 °C (test item concentration was approximately 0.1%). Therefore, according to criteria in the guidline document, the substance is not considered as surface active material.
