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:
- 1988
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: - EEC Directive 84/449, A.5 "Oberflachenspannung" (Amtsblatt der EG L 2S1/37, 19.9.84, Ringmethode) and ISO 304 ("Surface active agents - Determination of Surface Tension by Drawing up Liquid Films") 1978
- Deviations:
- yes
- Remarks:
- - using the Wilhelmy plate method instead of ring method
- Principles of method if other than guideline:
- As an alternative to the ring method, which is primarily suggested by the test guideline, we prefer to use the Wilhelmy plate method because it allows a better assessment of the time dependence of the surface tension, if present.
- GLP compliance:
- no
- Type of method:
- plate method
- Surface tension:
- >= 59.1 - <= 64.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 10 g/L
- Conclusions:
- The surface tension of test substance was determined to be 59 - 65 mN/m at 20°C (Filtrates of 10.0 g/L suspensions)
- Executive summary:
In this study conducted to generally accepted scientific standards (EU A. 5) the test material (EC 404-360-3) was determined to have a surface tension of 59 - 65 mN/m at 20°C (Filtrates of 10.0 g/L suspensions)
Reference
Slightly time dependence of surface tension was observed.
