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:
- OECD harmonised ring method
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Batch No.of test material: 151124012
- Expiration date of the lot/batch: 01 March 2020
- Purity test date: Not reported
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Ambient
- Stability under test conditions: Stable under normal conditions.
TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing: Approximately 100 mg of test item was diluted to volume (100 mL) with purified water. The resulting dispersion was then diluted in series 10 to 100 mL with purified water and then 4.14 to 100 mL with purified water.
- Final dilution of a dissolved solid, stock liquid or gel: The final sample concentration (4.1 mg/L) was equivalent to 90% of the saturation level determined in the water solubility test. - Surface tension:
- 51 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
- Remarks on result:
- other: see 'Remarks'
- Remarks:
- The surface tension of a 90% saturated solution of the test item.
- Conclusions:
- Triglycerides, C16 and C18 (unsaturated) is considered to be a surface active substance as the surface tension of a 90% saturated solution of the test item was 51.0 mN/m.
- Executive summary:
The surface tension of triglycerides, C16 and C18 (unsaturated) was determined in a study conducted according to OECD 115 and EC A.5 guidelines. The surface tension of a 90% saturated solution of the test item was determined at 20°C with a surface tension torsion balance using the OECD harmonised ring method.
The test item was considered to be surface active as the surface tension was determined to be 51.0 mN/m.
The study was conducted according to standard guidelines and is GLP-compliant and therefore is considered as reliable without restrictions.

From the measurements, it was observed that there was an initial decrease in surface tension readings. The final surface tension result was taken from the measurements between 10 and 30 minutes.
Mean calibration corrected surface tension = 53.5 mN/m
Harkins-Jordan corrected value = 51.0 mN/m
Description of key information
The test item was considered to be surface active as the surface tension was determined to be 51.0 mN/m.
Key value for chemical safety assessment
- Surface tension:
- 51
- in mN/m at 20°C and concentration in mg/L:
- 4.1
Additional information
The study to determine the surface tension of triglycerides, C16 and C18 (unsaturated) was conducted according to OECD 115 and EC A.5 guidelines. The surface tension of a 90% saturated solution of the test item was determined at 20°C with a surface tension torsion balance using the OECD harmonised ring method.
The study is a GLP compliant, guideline experimental study and is fully acceptable for assessment of this endpoint.
