Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
13 March - 15 May, 2007
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
Study has been performed according to OECD and/or EU guidelines and according to GLP principles.
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
OECD harmonised ring method
Key result
Surface tension:
69 mN/m
Temp.:
19.9 °C
Conc.:
1 046 mg/L

Mean measured surface tension of test substance: 62.9 mN/m

Mean multiplied by calibration factor (i.e. 1.10): 69.2 mN/m

Mean multiplied by calibration factor and Harkins-Jordan correction: 69.0 mN/m

Conclusions:
The surface tension of an aqueous test substance solution at a concentration of 1.046 g/l and at 19.9°C was determined to be 69.0 mN/m. Therefore, Ditetrahydrofurylpropane is considered not surface active.
