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:
- 07 August 2015 to 04 May 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Study conducted to OECD and EC guidelines and in compliance with GLP
- 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
- Type of method:
- OECD harmonised ring method
- Key result
- Surface tension:
- > 71 - < 71.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: Overall mean calibration corrected surface tension = 71.5 mN/m (rounded to ± 0.5 mN/m) Harkins-Jordan* corrected value = 70.5 mN/m
- Conclusions:
- The surface tension of a 1 g/L aqueous solution of test material was found to be 70.5 mN/m. As the result was greater than 60 mN/m, the substance was not considered to be surface active.
- Executive summary:
The surface activity of the test material was investigated in a study which was conducted under GLP conditions and in accordance with the standardised guidelines OECD 115 and EU Method A.5 following the OECD harmonised ring method.
Under the conditions of the study the surface tension of a 1 g/L aqueous solution of test material was found to be 70.5 mN/m. As the result was greater than 60 mN/m, the substance was not considered to be surface active.
