- key study
- 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)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- GLP compliance:

- Type of method:
- plate method
- Key result
- Surface tension:
- 73 mN/m
- Temp.:
- 20 °C
- Conc.:
- 5 g/L
- Surface tension:
- 60.38 mN/m
- Temp.:
- 20 °C
- Conc.:
- 100 mg/L
- Conclusions:
- The surface tension in the range of 5 and 100 g/L solution of the test substance in water showed a surface tension was between 73.00 and 64.38 N/m, respectively, at 20 ° C. The pure test substance was not surface active.
- Executive summary:
The surface tension of the test substance has been determined using the plate method in accordance with OECD TG 115 and EU Method A5 in compliance with GLP. The mean surface tension of duplicate mesurements using 5 and 100 g/L solution of the test substance in water showed a surface tension of 73.00 and 64.38 N/m, respectively, at 20 °C.
