Surface tension
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:
- guideline study with acceptable restrictions
- Justification for type of information:
- Guideline method conducted in a reliable laboratory within the spirit of GLP, but without CLP certification.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- GLP compliance:
- no
- Type of method:
- ring method
- Key result
- Surface tension:
- 38.5 mN/m
- Temp.:
- 23 °C
- Remarks on result:
- other: saturated solution
- Conclusions:
- A saturated solution of the test substance was determined to have a surface tension of 38.5 mN/m at 23 °C, using a du Nouy ring method according to OECD Guideline 115. The substance is evaluated as being surface active.
