- Study period:
- 02/07/2012 - 04/07/2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:

- Type of method:
- ring method
- Key result
- Surface tension:
- 35 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: The surface tension result is corrected for water calibration. Solution age was 98 minutes for test No 1 and 95 minutes for test No 2.
- Conclusions:
- The surface tension of the substance was determined to be 35.0 mN/m at a test concentration of 1 g/L and at 20 °C. The substance is concluded to have surface active properties.
Reference
The surface tension decreased over time, starting at 36 mN/m after a standing time of 10 minutes to a final stable reading of 35 mN/m after 95 to 98 minutes.
Description of key information
The surface tension of the test substance was determined in a GLP study according to test method EC A.5, to be 35.0 mN/m at a test concentration of 1 g/L and at 20 °C, following the ring method (Younis S, 2012).
Key value for chemical safety assessment
- Surface tension:
- 35
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The substance is concluded to have surface active properties.
