Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 11 to 18 January 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline study under GLP.
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:
70.5 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Conclusions:
The surface tension of a test solution of 1 g/L in water and at 20 °C was 70.5 mN/m. According to this, the test substance is considered not to be surface active.
Executive summary:

The OECD harmonized ring method was used for the determination of the surface tension of the test substance. The surface tension of a test solution of 1 g/L in water and at 20 °C was 70.5 mN/m. According to this, the test substance is considered not to be surface active.
