from 18 to 27 January 2012
Reliability:
1 (reliable without restriction)
Qualifier:
according to
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
yes
Remarks:
90% saturated solution for surface tension measurement: no impact on the integrity of the study data
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
yes
Remarks:
90% saturated solution for surface tension measurement: no impact on the integrity of the study data
GLP compliance:
yes (incl. certificate)
Type of method:
OECD harmonised ring method
Surface tension:
31.33 mN/m
Temp.:
20 °C
Conc.:
90 other: % saturated
Remarks on result:
other: Harkins-Jordan corrected result

After application of the calibration factor, the mean result was 34.04 mN/m. This result is significantly lower than 60 mN/m, and therefore correction using the Harkins-Jordan factor was performed. The Harkins-Jordan corrected result was 31.33 mN/m.

Conclusions:
The surface tension of CAE is 31.33 mN/m at 20°C (Harkins-Jordan corrected result).
Executive summary:

The surface tension of CAE at 20°C was determined to be 31.33 mN/m according to EC Method A5 and OECD guideline 115.

Description of key information

The surface tension of CAE is 31.33 mN/m at 20°C (Harkins-Jordan corrected result).
