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:
- 18 October 1999 -03 November 1999
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- GLP compliance:
- yes
- Type of method:
- OECD harmonised ring method
- Key result
- Surface tension:
- 72.7 mN/m
- Temp.:
- 19.5 °C
- Conc.:
- 90 vol%
- Conclusions:
- Determined using the OECD harmonised ring method, the surface tension of a 90% saturated aqueous solution of NB 6786-35 was 72.7 mN/m at 19.5oC.
- Executive summary:
In a GLP study, the surface tension of EC# 434-650-5 was determined using the OECD harmonised ring method (OECD Guideline 115). A test vessel containing a 90% saturated aqueous solution was positioned on a tensiometer test platform and the ring was positioned 2 -3 mm below the liquid surface. The platform was lowered to draw a lamella from the liquid surface. The maximum force, which arose just before the lamella was torn off, was used to calculate the surface tension (the calculation took into account the weight of the liquid in the lamella as drawn up by the ring, the solution density, the ring diameter, the wire diameter, acceleration due to gravity and the Harkins-Jordan correction).
The mean calculated surface tension at 19.5oC was 72.7 mN/m. This would not be considered surface active under the terms of the appropriate EC Directive, which stipulates that such substances have surface tensions of less than 60 mN/m.
- Endpoint:
- surface tension
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reason / purpose for cross-reference:
- read-across source
- Key result
- Surface tension:
- 72.81 mN/m
- Temp.:
- 19.5 °C
- Conc.:
- 90 vol%
- Conclusions:
- Determined using the OECD harmonised ring method, the surface tension of a 90% saturated aqueous solution of NB 6786-35 was 72.7 mN/m at 19.5oC.

In view of the structural and chemical similarities, it is considered that the results of this study can be used for read-across to EC# 457-320-2.

Description of key information
Determined using the OECD harmonised ring method, the surface tension of a 90% saturated aqueous solution of a structurally similar material [NB 6786-35] was 72.7 mN/m at 19.5oC. This result can be read-across to EC# 457-320-2
Key value for chemical safety assessment
- Surface tension:
- 72.7
