Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
Qualifier:
according to
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.
