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:
- other: According to international guideline(s), GLP-compliant, performed in recognized contract research organization, no restrictions, fully adequate for assessment.
- 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:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 63.5 mN/m
- Temp.:
- 19.8 °C
- Remarks on result:
- other: Surface tension of aqueous solution of WS400402 after correction by Harkins-Jordan
- Conclusions:
- The surface tension of the aqueous solution of WS400402 is 63.5 mN/m.
As the surface tension value was higher than 60 mN/m, WS400402 is not classified as surface active substance.
