Surface tension
Administrative data
Link to relevant study record(s)
- 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
- 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 (incl. QA statement)
- 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
