Administrative data
Link to relevant study record(s)
- 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
- 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.
Reference
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
Description of key information
Test performed according to OECD 115 (ring method)
Key value for chemical safety assessment
- Surface tension:
- 69
- in mN/m at 20°C and concentration in mg/L:
- 1 046
Additional information
Not surface active.
