Reference

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

Guideline:

OECD Guideline 115 (Surface Tension of Aqueous Solutions)

Deviations:

no

Qualifier:

according to guideline

Guideline:

EU Method A.5 (Surface Tension)

Deviations:

no

GLP compliance:

yes (incl. QA statement)

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.
