Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension

- experimental study
- Adequacy of study:
- key study
- Study period:
- 05.09.2019
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: Wilhelmy-Plate Method
- Version / remarks:
- Instrument: Krüss K20

- Other quality assurance:
- other: ISO 9001 and ISO 14001 environment
- Type of method:
- plate method
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and package No.of test material: lot #19953859
- Expiration date of the lot/batch: 16.01.2020 - Key result
- Surface tension:
- >= 31.85 - <= 31.85 mN/m
- Temp.:
- 20 °C
- Conc.:
- 397.2 mg/L
- Conclusions:
- As no clear solution could be obtained in water the surface tension could not be measured correctly due to poor water solubility of the substance. The surface tension is 31.85 mN/m
- Executive summary:
The surface tension is 31.85 mN/m
