Reference
Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
27 September 2011 - 12 June 2013
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
OECD harmonised ring method
Key result
Surface tension:
72 mN/m
Temp.:
20 °C
Conc.:
1.5 mg/L
Conclusions:
The surface tension of a 90 % saturated solution (approximately 1.5 mg/L) of TCD was found to be 72.0 mN/m. As the result was greater than 60 mN/m, the test substance was considered not to be surface active).

Description of key information

The surface tension of a 90% saturated aqueous solution of TCD was determined to be 72.0 mN/m

Key value for chemical safety assessment

Surface tension:
72
in mN/m at 20°C and concentration in mg/L:
1.53

Additional information

The surface tension of an aqueous solution of TCD was conducted as part of a package of physico-chemical testing for TCD (Huntingdon Life Sciences, 2013, Study number VHJ0054). The testing was conducted in compliance with GLP, and the surface tension was measured according to OECD test guideline 115 and EC test method A.5.

The surface tension of a 90% saturated solution (approximately 1.5 mg/L) solution of TCD was found to be 72.0 mN/m. As the result was greater than 60 mN/m, the test substance was considered not to be surface active.
