- Adequacy of study:
- key study
- Study period:
- 2015-07-23
- 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 (incl. QA statement)
- Type of method:
- OECD harmonised ring method
- Surface tension:
- 30.48 mN/m
- Temp.:
- 20.3 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of a 1 g/L aqueous solution of the test item Amphopropionate C12-18 at 20°C was determined to be: 30.48 mN/m (standard deviation ± 0.05 mN/m). Due to the fact that the surface tension is < 60 mN/m, the test item is classified as surface-active substance.
- Executive summary:
The surface tension of Amphopropionate C12 -18 (water content 59.7%) was determined according to OECD Guideline 115 (27 July 1995) and EU Method A.5 by the OECD harmonized ring method. The mean surface tension of an aqueous test substance solution at 20°C at a concentration of 1 g/L, was determined to be 30.48 mN/m. Therefore Amphopropionate C12 -18 is considered to be surface active.
Reference
The surface tension of the reference item n-heptane was determined on 2015-03-12 as 20.05 ± 0.01 mN/m (20 °C) and is within the acceptable range of 20.23 ± 0.22 mN/m.
The temperature of the test solution during the whole measurements was between 20.1 and 20.3 °C.
Description of key information

Key value for chemical safety assessment
- Surface tension:
- 30.48
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The surface tension of Amphopropionate C12 -18 (water content 59.7%) was determined according to OECD Guideline 115 (27 July 1995) and EU Method A.5 by the OECD harmonized ring method. The mean surface tension of an aqueous test substance solution at 20°C at a concentration of 1 g/L, was determined to be 30.48 mN/m. Therefore Amphopropionate C12 -18 is considered to be surface active.
