Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 26 September 2000 to February 2001
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to other study
- Reason / purpose for cross-reference:
- reference to other study
- Reason / purpose for cross-reference:
- reference to other study
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- yes
- Remarks:
- The cleaning of the apparatus was performed with chromosulfuric acid and with highly purified water. This deviation didn't impact the results or the quality of the study
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 59.1 mN/m
- Temp.:
- 20.2 °C
- Conc.:
- 316 mg/L
- Conclusions:
- A solution of the test substance (concentration is 316 mg/l, 90% of the saturated solution) shows a surface tension which is lower than that of pure water. The surface tension stabilizes at 59.1 mN/m, which is 13.7 mN/m lower than the surface tension of pure water.
Based on its surface tension, the test item is considered to possess surface active properties. - Executive summary:
The test item surface tension was determined with the ring method according to recognised guideline and under GLP.
A minor deviation which didn't impact the results or the quality of the study was observed.
Before measurement of test item surface tension, the apparatus was calibrated with highly water. The surface tension of test item solution in water, stabilizes at 59.1 mN/m, which is 13.7 mN/m lower than the surface tension of pure water. Based on its surface tension, the test item is considered to possess surface active properties.
Reference
The solution was prepared 5 minutes before it was put the tensiometer vessel.
After 165 minutes, the surface tension of the test item solution in water at a temperature of 20°C stabilizes to 59.1 mN/m. Based on its surface tension, the test item is considered to possess surface active properties.
Description of key information
The surface tension of the test item was determined in an experimental key study of Klimisch validity 1. A deviation which didn't impact the results or the quality of the study was observed
Key value for chemical safety assessment
- Surface tension:
- 59.1
- in mN/m at 20°C and concentration in mg/L:
- 316
Additional information
Based on its surface tension, the test item is considered to possess surface active properties.
