Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
02/07/2010
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Conducted at a GLP accredited laboratory to GLP. There is the possibility of some degradation of the test substance, although result is in line with expectations
Qualifier:
according to
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
ring method
Surface tension:

Temp.:
20 °C
Conc.:
1 g/L

The calibration factor is determined by measuring the Surface Tension of water and comparing the value obtained in literature. The corrected value is taken from a table compiled on the basis of the Harkins-Jordan correction.

Description of key information

The surface tension is 34.1 mN/m at 20 °C

Key value for chemical safety assessment

Surface tension:
34.1
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

The surface tension of the substance was measured in a test conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A5 (ring method) under GLP [Younis S (2010)]. Due to the high solubility of the substance, a concentration of 1 g/L was used. Measurements were made in duplicate. The derived value for surface tension was 34.1 mN/m at 20 °C.
