Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: ECHA provided robust study summary
- Qualifier:
- according to guideline
- Guideline:
- other: 92/69/EEC, A5 (OECD Harmonised ring method)
- GLP compliance:
- yes
- Type of method:
- ring method
- Key result
- Surface tension:
- 43.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1.029 g/L
- Conclusions:
- The surface tension of the test item in water at a concentration of 1.029 g/L is 43.5 mN/m. Based on the criteria as outlined in the guideline, it is concluded that the test item should be regarded as a surface active material.
- Executive summary:
The determination of the surface tension of an aqueous solution of teh test item was based on EEC-Directive 92/69 EEC, A.5 "Surface tension" (1992). The surface tension of an aqueous solution of the test item at a concentration of 1.029 g/L was 43.5 mN/m. Temperature of measurement was 20.0°C. Based on the criteria as outlined in the guideline, it is concluded that the test item should be regarded as a surface active material.
