Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- 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)
- 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:
- 71.887 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 000 mg/L
- Conclusions:
- According to the EC Directive, "TAZOBACTAM ACID" is not surface active because its surface tension is greater than 60 mN/m.
- Executive summary:
The surface tension of the test substance was determined with the ring method according to OECD- and EC-methods.
The mean surface tension of the test substance was 71.887 mN/m, standard deviation 0.061, at a temperature of 20.0 °C.
Reference
The surface tension was constant during the test. The mean value was therefore calculated from the determinations obtained 30 minutes after the preparation and later. The age of the surface was 30 min to 1 h 20 min. The mean surface tension of the test substance was 71.887 mN/m, standard deviation 0.061, at a temperature of 20.0 °C.
