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:
- EU Method A.5 (Surface Tension)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- plate method
- Surface tension:
- 62.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- For the test item a surface tension of 62.7 mN/m was determined at 20 °C.
- Executive summary:
To determine the surface tension of the test item a plate tensiometer was used which conforms with the procedure test method A.5, described in the EC Guideline.
A commercially available tensiometer based on the plate method has been used to measure the force which is required to withdraw a horizontally suspended plate from the surface of the test solution. The surface tension was determined in a solution of 1.0012 g test item in 1 L demineralized water (= approx. 1 g/L) at 20 °C.
For the test item a surface tension of 62.7 mN/m was determined at 20 °C.
Reference
For verification of the measured values the surface tension of demineralized water was also measured. With a correspondence of the measured value σ (20 °C) = 72.5 mN/m, to the theoretical value σ (20 °C) = 72.75 mN/m, cited in literature, the determination of the surface tension of the test item is considered as valid.
Description of key information
For the test item a surface tension of 62.7 mN/m was determined at 20 °C.
Key value for chemical safety assessment
- Surface tension:
- 62.7
- in mN/m at 20°C and concentration in mg/L:
- 1 001.2
