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:
- 18 January 2011 to 01 June 2012
- 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
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- OECD harmonised ring method
- Surface tension:
- 51.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 170 mg/L
- Conclusions:
- The surface tension of a 90% saturated aqueous solution of Rikabinol HB was found to be 51.5 mN/m. As the result was less than 60 mN/m, the test substance was considered to be surface active.

Description of key information
The surface tension of a 90% saturated aqueous solution of Rikabinol HB was found to be 51.5 mN/m. As the result was less than 60 mN/m, the test substance was considered to be surface active.
Key value for chemical safety assessment
- Surface tension:
- 51.5
- in mN/m at 20°C and concentration in mg/L:
- 170
Additional information
The determination of surface tension of HBPA was determined with a surface tension torsion balance using harmonised ring method (Huntingdon Life Sciences, 2012, Study MOG0004). The procedure was designed to be compatible with the EC Method A.5 and the OECD test guideline 115, and was conducted in compliance with GLP.
The surface tension of a 90% saturated aqueous solution of HBPA was found to be 51.5 mN/m. As the result was less than 60 mN/m, the test substance was considered to be surface active.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
