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:
- 13 DEC 2010 - 12 JAN 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- European Commission Regulation (EC) No. 440/2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- 1995
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- ring method
- Surface tension:
- 20.2 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of the test item at 20°C with a concentration of 1 g/L is 20.2 mN/m.
- Executive summary:
The surface tension of the sample was tested according to EU Method A.5 and OECD 115 in a non-GLP study with a ring method. The surface tension of the test item at 20°C with a concentration of 1 g/L is 20.2 mN/m.
The test item has surface-active properties.
Reference
As the test item is highly hygroscopic, it was dried under vacuum at ambient temperature for 210 h before the performance of the measurement. An aqueous solution of the lest item in de-ionized water with a concentration of 1.0 g/L was prepared and treated with ultrasound for 45 min. The measurement of the surface tension with the lest item was carried out at 20 ± 0.5°C.
The measurements of the surface tension:
1. measurement: 20.18 mN/m
2. measurement: 20.19 mN/m
3. measurement: 20.18 mN/m
4. measurement: 20.16 mN/m
5. measurement: 20.16 mN/m
6. measurement: 20.15 mN/m
Mean value: 20.17 mN/m (corrected by Zuidema and Waters)
Due to the fact that the surface tension is lower than 60 mN/m, the lest item has surface-active properties.
Description of key information
The surface tension of the sample was tested according to EU Method A.5 and OECD 115 in a non-GLP study with a ring method. The surface tension of the test item at 20°C with a concentration of 1 g/L is 20.2 mN/m.
The test item has surface-active properties.
Key value for chemical safety assessment
- Surface tension:
- 20.2
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Due to the fact that the surface tension is lower than 60 mN/m, the test item has surface-active properties.
