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
Type of method:
ring method
Specific details on test material used for the study:
- Batch: 8191-34
- Purity: 97.8% (expressed as primary amine, % of total)
Key result
Surface tension:
62.4 mN/m
Temp.:
20 °C
Conc.:
1 045 mg/L

The measured value was corrected for calibration and a further Harkins-Jordan correction was applied.

Conclusions:
The surface tension of the substance was determined to be 62.4 mN/m at a test concentration of 1.045 g/L and at 20 °C. The substance is concluded not to have surface active properties.

Description of key information

The surface tension of the substance was determined, in a GLP study according to test methods EC A.5 and OECD 115, to be 62.4 mN/m at a test concentration of 1.045 g/L and at 20 °C, following the ring method (Van der Baan-Treur, 2003).

Key value for chemical safety assessment

Surface tension:
62.4
in mN/m at 20°C and concentration in mg/L:
1 045

Additional information

The substance is concluded not to have surface active properties.
