Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because water solubility is below 1 mg/L at 20°C
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 1993-07-09 to 1994-10-13
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- EEC 92/69
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- 1981
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- ring method
- Specific details on test material used for the study:
- Analytical purity: >= 99.65 %
Lot/batch No.: 93.166 - Key result
- Temp.:
- 20 °C
- Conc.:
- 0.005 mg/L
- Remarks on result:
- not determinable because of methodological limitations
- Conclusions:
- Water solubility of the test article was determined as lower than 0.24 mg/L (test A 6). Therefore, in agreement with EEC Directive 92/69, surface tension of aqueous solution of the test article was not determined as substances with a water solubility lower than 1 mg/L need not to be tested.
- Executive summary:
The surface tension is defined as the free enthalpy of the surface per unit area of surface. The surface tension is measured at the surface of a solution of the test article in water. The knowledge of the water solubility of the test article is a prerequisite to the performance of this test.
Water solubility of the test article was determined as lower than 0.24 mg/L (EU-Method A 6). Therefore, in agreement with EEC Directive 92/69, surface tension of aqueous solution of the test article was not determined as substances with a water solubility lower than 1 mg/L need not to be tested.

Description of key information
Water solubility of the test article was determined as lower than 0.24 mg/L (EU-Method A.6, Water solubility). Therefore, in agreement with EEC Directive 92/69, surface tension of aqueous solutions of the test article was not determined, as substances with a water solubility below 1 mg/L do not need to be tested.
Key value for chemical safety assessment
