Rationale for reliability incl. deficiencies:
other: Study has been performed according to OECD and EC guidelines and GLP principles.
Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Version / remarks:
July 27, 1995

GLP compliance:
yes
Type of method:
OECD harmonised ring method
Key result
Surface tension:
ca. 47.2 mN/m
Temp.:
20 °C
Conc.:
90 other: Tested concentration: 90% of the saturation concentration
Conclusions:
The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 47.2 mN/m. 
Executive summary:

The OECD harmonized ring method was applied for the determination of the surface tension of the test item, according to EC A.5 and OECD Guideline No. 115

The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 47.2 mN/m. 

According to this, the test item is considered to be surface active.

Description of key information

The obiective of the study was the determination of the surface tension of the itest item, according to EC A.5 and OECD Guideline No. 115

Specifically, the OECD harmonized ring method was applied

The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 47.2 mN/m.

Key value for chemical safety assessment

Surface tension:
47.2

Additional information

Tested concentration: 90% of the saturation concentration
