- key study
- Study period:
- from 11 May 2017 to 06 July 2017
- 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:
- 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- 1995
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- OECD harmonised ring method
- Key result
- Surface tension:
- 69.1 mN/m
- Temp.:
- 20 °C
- Remarks on result:
- other: Conc.= 90% of saturation solubility
- Conclusions:
- The surface tension of an aqueous substance solution at 90% of its saturation solubility was determined to be 69.1 mN/m (at 20°C).
- Executive summary:
Using the OECD harmonized ring method in a GLP study according to EC A.5 and OECD 115, the surface tension of an aqueous substance solution at 90% of its saturation solubility was determined to be 69.1 mN/m (at 20°C). According to the EC A.5 guideline the substance is not surface active.
