Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 29 June, 2009 - 6 August, 2009
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The study has been performed according to OECD and/or EC guidelines, and according to GLP principles.
- 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 (incl. QA statement)
- Type of method:
- ring method
- Surface tension:
- 47.4 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The OECD harmonized ring method was used for the determination of the surface tension of 2-sec-butylphenol. The surface tension of a test solution at a concentration of 1 g/l at 20.0°C was 47.4 mN/m. According to this, the test substance is considered to be surface active.
- Executive summary:
The surface tension of 2 -sec-butylphenol was determined by the ring method. The method followed the OECD Guideline 115 (Surface Tension of Aqueous Solutions) and EU Method A. 5 (Surface tension). Five measurements were performed until a constant value on the surface tension was reached (< 0.5 mN/m).
The surface tension of a test solution at a concentration of 1 g/l at 20.0°C was 47.4 mN/m. According to this, the test substance is considered to be surface active.

Additional information
The surface tension of 2 -sec-butylphenol was determined by the ring method. The method followed the OECD Guideline 115 (Surface Tension of Aqueous Solutions) and EU Method A. 5 (Surface tension).Five measurements were performed until a constant value on the surface tension was reached (< 0.5 mN/m).
The surface tension of a test solution at a concentration of 1 g/l at 20.0°C was 47.4 mN/m. According to this, the test substance is considered to be surface active.Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
