Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2007-03-19 to 2007-06-20
- 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:
- EEC publictaion L383, December 29, 1992
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- July 27th, 1995
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- OECD harmonised ring method
- Surface tension:
- 38.2 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1.11 g/L
- Conclusions:
- The surface tension of an aqueous test substance solution at 20°C at a concentration of 1.11 g/L, was determined to be 38.2 mN/m. Therefore Amphopropionate C8 is considered surface active.
- Executive summary:
The surface tension of Amphopropionate C8 was determined according to OECD Guideline 115 (27 July 1995) and EU Method A.5 (29 December 1992) by the OECD harmonized ring method.The surface tension of an aqueous test substance solution at 20°C at a concentration of 1.11 g/L was determined to be 38.2 mN/m. Therefore Amphopropionate C8 is considered to be surface active.

Additional information
The surface tension of Amphopropionate C8 was determined according to OECD Guideline 115 (27 July 1995) and EU Method A.5 (29 December 1992) by the OECD harmonized ring method. The surface tension of an aqueous test substance solution at 20°C at a concentration of 1.11 g/L was determined to be 38.2 mN/m. Therefore Amphopropionate C8 is considered to be surface active.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
