Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 16.07. - 27.07.07
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- OECD harmonised ring method
- Key result
- Surface tension:
- 68.3 mN/m
- Temp.:
- 20 °C
- Conc.:
- 21.53 mg/L
- Conclusions:
- The surface tension was determined to be 69.3 mN/m at 20°C and therefore the test item is not considered to be a surface active substance.
- Executive summary:
The surface tension of the test item was determined according to EU Method A.5. The mean value of three determinations was determined to be 69.3 mN/m at 20°C. Therefore, the item has no surface-active properties.
Reference
Three individual values were determined:
68.23 mN/m
68.36 mN/m
68.22 mN/m
Description of key information
The surface tension was determined to be 69.3 mN/m at 20°C and therefore the test item is not considered to be a surface active substance.
Key value for chemical safety assessment
- Surface tension:
- 69.3
- in mN/m at 20°C and concentration in mg/L:
- 21.53
Additional information
The surface tension of the test item was determined according to EU Method A.5. The mean value of three determinations was determined to be 69.3 mN/m at 20°C. Therefore, the item has no surface-active properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
