Reference
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:
EU Method A.5 (Surface Tension)
Deviations:
no
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
GLP compliance:
yes (incl. certificate)
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:

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.
