1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Version / remarks:
1995
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
GLP compliance:
no
Type of method:
ring method
Key result
Surface tension:
> 60 mN/m
Temp.:
20 °C
Remarks on result:
other: no conc. available

Due to the fact that the surface tension showed a time-dependence no mean value could be reported. However, the surface tension was higher than 60 mN/m, the test item had no surface-active properties

Conclusions:
The test item had no surface-active properties.
Executive summary:

The surface tension of the aqueous solution of the test item at 20 °C was performed according to European Commission Regulation (EC) No. 440/2008, method A.5. and OECD 115 (1995). The surface tension of the aqueous solution of the test item at 20 °C was higher than 60 mN/m. The test item had no surface-active properties.

Description of key information

The test item had no surface-active properties.

Key value for chemical safety assessment
