Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1987
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- ring method
- Key result
- Surface tension:
- 71.8 mN/m
- Temp.:
- 20.5 °C
- Conc.:
- 0.02 mg/L
- Conclusions:
- The surface tension of a saturated aqueous solution of the test item was determined to be 71.8 mN/m at 20.5°C (concentration of 0.02 mg/l). Therefore, the substance does not have surfacte active properties.
- Executive summary:
The study was performed 1987 as GLP-test following EU-testing method A.5 applying the ring method acc. Lecomte de Noüy. The surface tension of a saturated solution (concentration: 0.02 mg/l) was found to be 71.8 mN/m at room temperature. The test item does not need to be regarded as surface active material. An additional study conducted by another lab gave a surface tension of 72.32 mN/m at 20°C and a concentration of 0.020 mg/litre.

Description of key information
The surface tension of an aqueous solution was measured at two different test laboratories. In both labs, the studies were performed under GLP and in accordance with EU-testing method A.5. The test resulting in a value of 71.8 mN/m was identified as key study and used for the safety assessment.
Key value for chemical safety assessment
- Surface tension:
- 71.8
- in mN/m at 20°C and concentration in mg/L:
- 0.02
