experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
GLP compliance:
yes
Type of method:
OECD harmonised ring method
Specific details on test material used for the study:
Batch: CDC-003
Key result
Surface tension:
73.5 mN/m
Temp.:
20 °C
Conc.:
90 other: % of the test substance saturation solubility in water
Conclusions:
The surface tension of a test solution at 90% of the test substance saturation solubility in water and at 20°C was 73.5 mN/m. According to this, the
test substance is considered not to be surface active.

Description of key information

The surface tension of the test material was determined using the OECD harmonised ring method.

Key value for chemical safety assessment

Surface tension:
73.5

Additional information

The surface tension of the test material at 90% saturation in water at 20°C was 73.5 mN/m. Accordingly, the test substance is not considered to be surface active.
