Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 05 May - 15 October 2008
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- 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
- Type of method:
- ring method
- Key result
- Surface tension:
- 73.6 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The OECD harmonized ring method was used for the determination of the surface tension of the test substance. The surface tension of a test solution at a concentration of 1 g/l and at 20.2°C was 73.6 mN/m. According to this, the test substance is considered not to be surface active.

Description of key information
The OECD harmonized ring method was used for the determination of the surface tension of the test substance. The surface tension of a test solution at a concentration of 1 g/l and at 20.2°C was 73.6 mN/m. According to this, the test substance is considered not to be surface active.
Key value for chemical safety assessment
- Surface tension:
- 73.6
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
