- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- 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)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- plate method
- Remarks:
- DIN EN 14370
- Surface tension:
- 27.9 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of Di-C12-18 alkyldimethyl ammonium chloride was determined to be 27.9 ± 0.08 mN/m at 20°C and 1 g/L.
- Executive summary:
The surface tension of Di-C12-18 alkyldimethyl ammonium chloride was determined according to OECD Guideline 115 and EU method A.5 using the plate method. The surface tension was determined to be 27.9±0.08 mN/m at 20°C and a concentration of 1 g/L. The test item shows a surface tension lower than 60 mN/m and is thus considered to be a surface-active material.
