Reference
Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
04 February 2013
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.5 (Surface Tension)
Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
GLP compliance:
yes (incl. QA statement)
Type of method:
ring method
Surface tension:
53.6 mN/m
Temp.:
20 °C
Conc.:
1.004 g/L
Conclusions:
The surface tension of the aqueous solution of the substance is 53.6 mN/m.
As the surface tension value was lower than 60 mN/m, the test item is classified as surface active substance.
Executive summary:

The surface tension of a 1.004g/L aqueous solution of the substance was measured at 20 °C in a GLP study performed according to EU Method A.5 using the ring method. The surface tension was 53.6 mN/m, indicating the substance is surface active.

Description of key information

The surface tension of the aqueous solution of the substance is 53.6 mN/m indicating the substance is surface active.

Key value for chemical safety assessment

Surface tension:
